Increasing time limit for Python

Posted on Sept. 19, 2023, 5:04 p.m.

To prevent valid solutions from receiving a Time Limit Exceeded (TLE) verdict in Python, the submission time limits for Python have been extended to five times their original values. For instance, if the specified time limit is 1000 milliseconds (ms), when you submit code in Python, the effective time limit will be 5000 ms. Furthermore, all previous Python submissions that received a TLE verdict have been rejudged with the updated time limit. This adjustment aims to ensure fair assessment and accuracy in evaluating Python solutions.
