Don't do that.

The advice to "only import the module" works (How to avoid circular imports in Python?).
But you'd be better off putting your functions into more files that are arranged in a hierarchy.
In other words, break the cycle.
It will be beneficial for the organization of your code,
and of your unit tests,
and for how you think about your high level problem.

Here, the definitions of want_to_call() and func1() belong in additional files, which both im1 & im2 import.

Tests should depend upon target code, not the other way around.

  your answer is good but I am doing this in django like one is views.py and 2nd file is some services.py, so I want to do that thing only in views.py. And Second thing, importing a file instead of function may create performance problem because I have so many functions and so many things in views.py, by the way your answer is also very helpful thanks

  Even for views & services, you still have an opportunity to evict common functions into some utility.py file. As far as elapsed time goes, the import happens just once when django starts up. Your code is small, relative to the other libraries you are importing, so absent timing results I wouldn't worry much about such overheads, they're not the dominant source of delay.
