C:\\books\\python' Modules can be imported using the module name within the package name. ") 'C:\\books\\python' Modules can be imported by importing the modules specifically from the package. ") 'C:\\books\\python' NOTE: Python includes a reload(module) function that reloads a module. This can be extremely useful during development if you need to update a module and reload it without terminating your program. However, objects created before the module is reloaded are not updated, so you must be careful in handling those objects.

Return x*x ... >>> print square(3) 9 NOTE: Functions can be treated as any other Python object. In addition to being called, they can be assigned as a value to a list or dictionary, passed as an argument, returned as a value, and so on. The following code shows an example of using the lambda operator to assign an anonymous function to a variable: >>>bigger = lambda a, b : a > b >>>print bigger(1,2) False >>>print bigger(2,1) True Python Objects, Modules, Classes, and Functions Namespaces and Scoping Scoping in Python revolves around the concept of namespaces.

The argument m can be a specific assignment, a dictionary of variable values, or a keyword list. The encoding method takes only encoding such as utf-8, utf-16, iso-8859-1, and ascii as its single argument and returns a string encoded in that format. Strings can be converted to unicode by several different methods. The decode method returns a unicode form of the string. NOTE: The ASCII encoding allows only for characters up to 128. If your string includes characters that are above that range, you will need to translate those characters before encoding the string to ASCII.
