how to easily create a list of already existing item

[deanhystad]

You can do anything in Python. Python reflects everything, so programs can snoop out which variables and which functions and which methods are available. You can write functions that rewrite themselves during runtime for heavens sake. But there are also things you should probably not do in Python. You should not write programs that have lots of variables that hold related information, you should use one of the collection variable types instead (dictionary, list, tuple, set...).
