How do I find and remove unused functions in Python code files?

Question

I have a Python code file with many functions in it. I'm only using a few. Is there a tool available to remove all of the unused ones for me?

What do you mean by "remove the functions"? Do you mean actually directly edit the source files to remove them? — Pika Supports Ukraine, Mar 21 '19 at 03:11
Maybe you're looking for something like this: https://github.com/jendrikseipp/vulture\ — CryptoFool, Mar 21 '19 at 03:12
You keep saying things like "this" and "these", but I see no code or references to code. — CryptoFool, Mar 21 '19 at 03:14
It is just a python program with many functions, but I only need one or two function in it... — Wrp Yuexia, Mar 21 '19 at 03:17
Steve, I think the link you post here is actually what I need...Thank you very much~ — Wrp Yuexia, Mar 21 '19 at 03:19

As Steve mentioned in the comments, you could use Vulture.

Here's an example from the documentation

Consider the following Python script (dead_code.py):

import os

class Greeter:
    def greet(self):
        print("Hi")

def hello_world():
    message = "Hello, world!"
    greeter = Greeter()
    greet_func = getattr(greeter, "greet")
    greet_func()

if __name__ == "__main__":
    hello_world()

Calling

vulture dead_code.py

results in the following output:

dead_code.py:1: unused import 'os' (90% confidence)
dead_code.py:4: unused function 'greet' (60% confidence)
dead_code.py:8: unused variable 'message' (60% confidence)

After reading this post i installed vulture and the hardest thing to do was to add it to my tools list in pyscripter. Works like a charm — Peter Hedlund, Aug 28 '19 at 16:01
