This guide aims to show examples of use of all Python Library Reference functions, methods and classes. At this point, only the more widely used modules were added and only functions use examples are given. Python version 2.5 was used for examples unless noted otherwise. Example of output of a function is shown in the form of function_call(args) # result, when result is the actual output, it is shown after the comment sign, if it's a description of an outcome, e.g. a raised exception, it will be shown in square brackets:
math.sqrt(9) # 3.0
1/0 # [raises ZeroDivisionError]
Note that use of function is shown as if it was imported directly to current namespace, e.g. pow(2,3) instead of math.pow(9).
