Which answer is correct?

Add `global count` at the top of the function. This tells Python to use the module-level variable instead of creating a local one.

— global_user

Pass `count` as a parameter and return the new value: `def inc(count): return count + 1`. Avoid `global` — it makes code harder to test and reason about.

— functional_py

Use a class or module-level dict to hold mutable state: `state = {"count": 0}` and `state["count"] += 1`. No `global` needed because you're mutating the object, not reassigning the name.

Just remove the `global` keyword — Python automatically reads global variables.
