Have you worked with request rate limiting mechanisms in your projects?

Yes, in Python projects, I often used rate limiting mechanisms to protect APIs from overload and prevent abuse.

One common method is to use libraries such as ratelimit or limits, which allow setting a maximum number of requests within a certain period.

An example using a decorator to limit to 10 requests per minute:

from ratelimit import limits, sleep_and_retry

@sleep_and_retry
def call_api():
    # call API
    pass

@sleep_and_retry
@limits(calls=10, period=60)
def limited_function():
    call_api()

You can also implement your own mechanism using Redis or other storage to count requests by user key or IP.
