Global Request Counter

Medium ⏱ 12 min 49% acceptance ★★★★★ 4.6
A module-level variable request_count = 0 already exists. Write a function log_request() that increments request_count by 1 using the global keyword and returns the new value. This models a simple in-process request counter.

Examples

Example 1
Input
log_request()
log_request()
Output

Explanation

Each call increments the shared module-level counter.

Constraints

  • request_count must be declared at module scope, not passed as a parameter.
  • The function must genuinely mutate the outer variable, not shadow it.

Hints

Hint 1

Without the global keyword, request_count += 1 inside the function would raise an UnboundLocalError.

Hint 2

Declare `global request_count` as the first line of the function body.
