The capacity to express oneself well in writing is a critically important skill used throughout life in myriad circumstances. While rules regarding grammar, punctuation, and proper sentence structure have changed somewhat over the years, they still matter tremendously. A misplaced or missing comma can change the entire meaning of a sentence. Ah, the lowly comma, so abused, so misunderstood, yet a critical component to our language. Consider the old standby, 'Let's eat, Grandma!' without the comma. It is far from alone. Punctuation replaces vocal inflection and body language of speech when we translate it to the page. It brings clarity to the words. How punctuation can change the meaning of a sentence is seen in a non-classic pairing,

Formatting has changed in recent years. The steadfast rule of two spaces after a period is rapidly disappearing. APA, MLA, and other research formats no longer require it, accepting the more commonly used single space that has taken over vernacular writing and publishing. After all, a blank space takes up just as much room as a letter, so let's fill it up.

Are you old enough to have learned how to type on a manual or electric typewriter? Probably not. They've become tools of the past, replaced by dedicated word processing equipment, then personal computers. Being able to write on a computer has become part of our educational system from kinder on up. Yet what was done with typewriters is still done today - writing, creating conceptually new information, leaving a little piece of history, putting forth ideas to see where they take us. We rely heavily on our word processing programs to correct us because of the importance of being accurate, especially if they are words we are putting out into the world with our name on it. We want to get it right.
In our contemporary culture of instant messaging with limited space, abbreviations and an utter lack of punctuation and even proper spelling has taken over. At a local elementary school I was appalled to discover children were learning how to interpret IMs and write their own in place of lessons on how to properly construct a sentence or paragraph.
Yet the need to write in the appropriate format, spelling and grammar correct, punctuation in the right place, are still an imperative. In scholastic circles professors have to express themselves clearly to pass on lessons to their students. In turn, students have to be able to interpret that information, formulate their own ideas, and write about it in a manner that is not only proper but holds the reader's interest. Masters' theses and doctoral dissertations must have proper grammar, punctuation, and precise formatting, or they will be rejected. For the reader, poor formatting, punctuation, and grammar are stoppers. It interrupts the flow of thought and may even give rise to questioning the veracity of the entire paper because of a smattering of distracting mistakes.
In the workplace and in the classroom, copying pounds of data is a common and frequently essential practice. However, that process also brings forward computerized code, extra lines, ellipses gone wild, missing or garbled characters, and a rash of errors that need to be corrected. New paint x 1 2 1. Cleaning it up is incredibly tedious, takes too much valuable time and attention, and the average eye may skip over vital mistakes. If you lead the hectic life most students and instructors do, you simply don't have time to check every little detail. Take 'smart quotes' for instance, those little straight quotes that don't match the rest of the text's familiar curly quotes. Or tabs that are just slightly out of alignment that throw off the look of the entire page. How good are you at those Facebook quizzes that test your editor's eye? Most people read right past an extra 'the' or a missing word. Yet all those corrections matter. It can mean the difference between understanding what is on the page and the writer being, well, wrong.
You're prepping your resume, cutting and pasting from old ones to get it just right for that perfect job. Did you notice that weird character in the middle of the page before you sent it? Was it spaced evenly, bringing the eye to the most pertinent points? Were all the apostrophes in the right places? Did you use brackets where you should have used parentheses? A short dash where there should be a long one? A circumflex where a tilde should be? Do you even know what a circumflex or a tilde is? You may not know the difference, but your future boss might. A simple mistake may make a difference between being called for an interview and ending in the reject file. After all, they are going to expect nothing less than your best if you get the job. If there are mistakes in what you present, it's pretty much over before you begin.

In more ancient times most people turned to scribes for their writing needs, because they did not know how to read or write. We have long since learned that a solid education opens the world to us. Without reading and writing there is no education. Without systems of punctuation, formatting, and sentence structure, there is no consistency so that we may learn and pass on what we know. Yet in today's fast-paced world we forget how truly important the proper writing is. It is our word. Our voice. A little fragment of who we are. Let's try and get it right.
Until now error messages haven’t been more than mentioned, but if you have triedout the examples you have probably seen some. There are (at least) twodistinguishable kinds of errors: syntax errors and exceptions.
8.1. Syntax Errors¶
Syntax errors, also known as parsing errors, are perhaps the most common kind ofcomplaint you get while you are still learning Python:
The parser repeats the offending line and displays a little ‘arrow’ pointing atthe earliest point in the line where the error was detected. The error iscaused by (or at least detected at) the token preceding the arrow: in theexample, the error is detected at the function
print()
, since a colon(':'
) is missing before it. File name and line number are printed so youknow where to look in case the input came from a script.8.2. Exceptions¶
Even if a statement or expression is syntactically correct, it may cause anerror when an attempt is made to execute it. Errors detected during executionare called exceptions and are not unconditionally fatal: you will soon learnhow to handle them in Python programs. Most exceptions are not handled byprograms, however, and result in error messages as shown here:
The last line of the error message indicates what happened. Exceptions come indifferent types, and the type is printed as part of the message: the types inthe example are
ZeroDivisionError
, NameError
and TypeError
.The string printed as the exception type is the name of the built-in exceptionthat occurred. This is true for all built-in exceptions, but need not be truefor user-defined exceptions (although it is a useful convention). Standardexception names are built-in identifiers (not reserved keywords).The rest of the line provides detail based on the type of exception and whatcaused it.
The preceding part of the error message shows the context where the exceptionoccurred, in the form of a stack traceback. In general it contains a stacktraceback listing source lines; however, it will not display lines read fromstandard input.
Built-in Exceptions lists the built-in exceptions and their meanings.
8.3. Handling Exceptions¶
It is possible to write programs that handle selected exceptions. Look at thefollowing example, which asks the user for input until a valid integer has beenentered, but allows the user to interrupt the program (using Control-C orwhatever the operating system supports); note that a user-generated interruptionis signalled by raising the
KeyboardInterrupt
exception.The
try
statement works as follows.- First, the try clause (the statement(s) between the
try
andexcept
keywords) is executed. - If no exception occurs, the except clause is skipped and execution of the
try
statement is finished. - If an exception occurs during execution of the try clause, the rest of theclause is skipped. Then if its type matches the exception named after the
except
keyword, the except clause is executed, and then executioncontinues after thetry
statement. - If an exception occurs which does not match the exception named in the exceptclause, it is passed on to outer
try
statements; if no handler isfound, it is an unhandled exception and execution stops with a message asshown above.
A
try
statement may have more than one except clause, to specifyhandlers for different exceptions. At most one handler will be executed.Handlers only handle exceptions that occur in the corresponding try clause, notin other handlers of the same try
statement. An except clause mayname multiple exceptions as a parenthesized tuple, for example:A class in an
except
Crossover 19 0 15. clause is compatible with an exception if it isthe same class or a base class thereof (but not the other way around — anexcept clause listing a derived class is not compatible with a base class). Forexample, the following code will print B, C, D in that order:Note that if the except clauses were reversed (with
exceptB
first), itwould have printed B, B, B — the first matching except clause is triggered.The last except clause may omit the exception name(s), to serve as a wildcard.Use this with extreme caution, since it is easy to mask a real programming errorin this way! It can also be used to print an error message and then re-raisethe exception (allowing a caller to handle the exception as well):
The
try
… except
statement has an optional elseclause, which, when present, must follow all except clauses. It is useful forcode that must be executed if the try clause does not raise an exception. Forexample:The use of the
else
clause is better than adding additional code tothe try
clause because it avoids accidentally catching an exceptionthat wasn’t raised by the code being protected by the try
…except
statement.When an exception occurs, it may have an associated value, also known as theexception’s argument. The presence and type of the argument depend on theexception type.
The except clause may specify a variable after the exception name. Thevariable is bound to an exception instance with the arguments stored in
instance.args
. For convenience, the exception instance defines__str__()
so the arguments can be printed directly without having toreference .args
. One may also instantiate an exception first beforeraising it and add any attributes to it as desired.If an exception has arguments, they are printed as the last part (‘detail’) ofthe message for unhandled exceptions.
Exception handlers don’t just handle exceptions if they occur immediately in thetry clause, but also if they occur inside functions that are called (evenindirectly) in the try clause. For example:
8.4. Raising Exceptions¶
The
raise
statement allows the programmer to force a specifiedexception to occur. For example:The sole argument to
raise
indicates the exception to be raised.This must be either an exception instance or an exception class (a class thatderives from Exception
). If an exception class is passed, it willbe implicitly instantiated by calling its constructor with no arguments:If you need to determine whether an exception was raised but don’t intend tohandle it, a simpler form of the
raise
statement allows you tore-raise the exception:8.5. Exception Chaining¶
The
raise
statement allows an optional from
which enableschaining exceptions by setting the __cause__
attribute of the raisedexception. For example:![Clean Clean](https://fbcd.co/images/products/de4da9b0f4e68f78a88274cb83ae7642_resize.jpg)
This can be useful when you are transforming exceptions. For example:
The expression following the
from
must be either an exception orNone
. Exception chaining happens automatically when an exception is raisedinside an exception handler or finally
section. Exception chainingcan be disabled by using fromNone
idiom:8.6. User-defined Exceptions¶
Programs may name their own exceptions by creating a new exception class (seeClasses for more about Python classes). Exceptions should typicallybe derived from the
Exception
class, either directly or indirectly.Exception classes can be defined which do anything any other class can do, butare usually kept simple, often only offering a number of attributes that allowinformation about the error to be extracted by handlers for the exception. Whencreating a module that can raise several distinct errors, a common practice isto create a base class for exceptions defined by that module, and subclass thatto create specific exception classes for different error conditions:
Most exceptions are defined with names that end in “Error”, similar to thenaming of the standard exceptions.
Many standard modules define their own exceptions to report errors that mayoccur in functions they define. More information on classes is presented inchapter Classes.
8.7. Defining Clean-up Actions¶
The
try
statement has another optional clause which is intended todefine clean-up actions that must be executed under all circumstances. Forexample:If a
finally
clause is present, the finally
clause will execute as the last task before the try
statement completes. The finally
clause runs whether ornot the try
statement produces an exception. The followingpoints discuss more complex cases when an exception occurs:- If an exception occurs during execution of the
try
clause, the exception may be handled by anexcept
clause. If the exception is not handled by anexcept
clause, the exception is re-raised after thefinally
clause has been executed. - An exception could occur during execution of an
except
orelse
clause. Again, the exception is re-raised afterthefinally
clause has been executed. - If the
try
statement reaches abreak
,continue
orreturn
statement, thefinally
clause will execute just prior to thebreak
,continue
orreturn
statement’s execution. - If a
finally
clause includes areturn
statement, the returned value will be the one from thefinally
clause’sreturn
statement, not thevalue from thetry
clause’sreturn
statement.
For example:
A more complicated example:
As you can see, the
finally
clause is executed in any event. TheTypeError
raised by dividing two strings is not handled by theexcept
clause and therefore re-raised after the finally
clause has been executed.In real world applications, the
finally
clause is useful forreleasing external resources (such as files or network connections), regardlessof whether the use of the resource was successful.8.8. Predefined Clean-up Actions¶
Some objects define standard clean-up actions to be undertaken when the objectis no longer needed, regardless of whether or not the operation using the objectsucceeded or failed. Look at the following example, which tries to open a fileand print its contents to the screen.

The problem with this code is that it leaves the file open for an indeterminateamount of time after this part of the code has finished executing.This is not an issue in simple scripts, but can be a problem for largerapplications. The
with
statement allows objects like files to beused in a way that ensures they are always cleaned up promptly and correctly.After the statement is executed, the file f is always closed, even if aproblem was encountered while processing the lines. Objects which, like files,provide predefined clean-up actions will indicate this in their documentation.
