API Rate Limiter (Python) You are tasked with building a rate limiter for an API gateway. Implement a function that ensures no more than 1000 requests per second are processed. If the limit is exceeded, the function should return False; otherwise, return True. ans import time from collections import deque class RateLimiter: def __init__(self, max_requests=1000, window=1.0): self.max_requests = max_requests self.window = window # in seconds self.request_times = deque() def allow_request(self): current_time = time.time() # Remove timestamps outside the current window while self.request_times and self.request_times[0] <= current_time - self.window: self.request_times.popleft() if len(self.request_times) < self.max_requests: self.request_times.append(current_time) return True else: return False # Example usage: limiter = RateLimiter() # Simulate 1005 requests allowed = 0 for _ in range(1005): if limiter.allow_request(): allowed += 1 print("Allowed requests:", allowed) # Output: 1000
