I was asked this

Write a decorator count_calls that counts how many times the decorated function is called, stored as wrapper.calls. The function must still return its normal result and keep its name (use functools.wraps).

🧪 Practice

Write your solution, then press Run tests. Explain your approach out loud as you go.

Python
import functools

def count_calls(fn):
    pass

Output appears here. Press Run or Ctrl/⌘ + Enter.

Try it first. Struggling for a few minutes is how it sticks.
