Exceptions

As a beginner, a lot of errors are bound to happen in the course of running your codes. The moment the interpreter encounters an error, it terminates the program. There are two possible errors that can occur, a syntax error and an exception. A syntax error is caused when a command statement is not written in the correct format. For example,

Dictry = { }

print ( "Empty Dictionary: " )

print ( Dictry ))

SyntaxError: invalid syntax

The error was caused by the incorrect print statement in the 3rd line. An exception occurs when a properly constructed command statement results in an error. For an exception, the interpreter prints a Traceback in the window. These Tracebacks show you exactly where the error originated. For example,

Traceback (most recent call last):

File "C:/Python27/Lib/idlelib/bs.py", line 67, in <module>

Dictry_b.pop( 5 )

KeyError: 5

This traceback tells you that the error originated in the 67th line and was caused due to the absence of key 5 in the dictionary Dictry_b .
