You're right about the bug! Slight code tweak to your PR and it's failing linting. |

In handling error-responses from the server the code checks if it's possible to create a rate limit object from the headers through
RateLimit.from_http(headers). This function returns an object if rate limit info was found, and None otherwise.The next line of code wants to check if this value was not none, but does not do so explicitly:
if rate_limit. This causes python to evaluate it as a boolean and callRateLimit.__bool__. This will only returnTrueifself.remaining > 0, which would not be the case if the rate-limit was indeed exceeded.The proposed fix simply explicitly checks if the returned
RateLimitobject is notNone.
