Thank you. This does not import the names of the functions defined in example directly in the current symbol table. What combinations allows you to do is create an iterator from an iterable that is some length long.

As your code becomes longer, you’ll need to split it for easier maintenance. vterron / groupby_distance.py. Do I need itertools to solve this? See your article appearing on the GeeksforGeeks main page and help other Geeks. It only imports the module name example there. >>> import itertools >>> Step 2: Get all permutation & combination of a sequence. In this article, I would like to focus on five advanced functions that will simply iterations in more complex scenarios. When you do this, you execute the code of the module, keeping the scopes of the definitions so that your current file(s) can make use of these. If func is supplied, it should be a function of two arguments. Python allows developers placing definitions in a file and using them in a script or an interactive instance of the interpreter.
