Rest API - Rate Limiting and Throttling

Identify the error in this token bucket refill code snippet:

def refill_tokens(bucket):
  bucket.tokens += bucket.refill_rate
  if bucket.tokens > bucket.max_tokens:
    bucket.tokens = bucket.refill_rate

ANot increasing tokens by refill_rate

BMissing return statement

CResetting tokens to refill_rate instead of max_tokens

DUsing wrong comparison operator

Step-by-Step Solution

Solution:

Step 1: Analyze token reset logic
If tokens exceed max_tokens, they should be set to max_tokens, not refill_rate.
Step 2: Identify correct fix
Change assignment to bucket.tokens = bucket.max_tokens to fix the error.
Final Answer:
Resetting tokens to refill_rate instead of max_tokens -> Option C
Quick Check:
Reset to max_tokens when overflowing [OK]

Quick Trick: Reset tokens to max, not refill rate [OK]
