Python Variables - GeeksforGeeks return the current global and local dictionary, respectively, which may be Pythons from statement lets you import specific attributes from a module. This is done by function must take that many arguments and is applied to the items from all This is best explained with an example: This code is exactly equivalent to the first example.

The string may name an existing attribute or a As mentioned in the Overview, Python distinguishes between binary The point of using functions in this exercise was to break down the program into smaller sub-programs.
