Whenever we make a request to a specified URI through Python, it returns a response object. Asking for help, clarification, or responding to other answers. Since time.clock() is deprecated as of Python 3.3, you will want to use time.perf_counter() for system-wide timing, or time.process_time() for process-wide timing, just the way you used to use time.clock(): The new function process_time will not include time elapsed during sleep. Unfortunately, there is nothing built-in available for this so you have two options: The timebudget is a versatile and very simple library that you can use just in one line of code after pip install.
