So, how do you figure out how many people on the guest list will actually attend the wedding? I get asked this question all the time. I wish I had a 100%- guaranteed-tried-and-true solution to offer or at least a magic crystal ball to whip out of my emergency kit to answer with, but alas, I can only offer my best advice.
Python Programming/Modules - Importing a Module. 1  To use the functions and classes offered by a module, you have to import the module... 2  The above imports the math standard module, making all of the functions in that module namespaced by the module name. It imports all functions and all classes, if any. You can import the module under a different name:
Unlike in C++ and Java, Python variables don't contain explicit type information. If you're using a function that requires a string, you can pass variables of other types to it without throwing an exception, although your code may throw an exception when it tries to process the variable.The only data types you may need to convert to strings are compound data structures such as sets and lists.Python includes convenient functions and operators for iterating over the items in a data structure and appending characters to a string variable.n Python, you can call these methods from a string literal, so to concatenate list elements, for example, you can pass a list variable to a string literal's join method as in the following example: tokens = ['Hello', 'World'] #string tokens without whitespace.
