What are non-pure functions?
Any function that affects any state other than that of local variables is a non-pure function. Changing a global is non-pure, for example: some_list = [] def foo(bar): some_list.append(bar) foo(‘baz’) The function foo changed the state of some_list ; it is thus non-pure.
Does a non pure function return values?
In addition to returning a value, applying a non-pure function can generate side effects, which make some change to the state of the interpreter or computer.

This means that we can quickly understand a function and its dependencies, just by reading the function’s declaration.
Is a closure a pure function?
