your function catch the "FunctionTimedOut" exception and exit cleanly if possible. Every 2 seconds until your function is terminated, it will continue to raise FunctionTimedOut. The terminating of the timed-out function happens in the context of the thread and will not block main execution. ...

This function can be used to find the time taken for a piece of code to execute. All we have to do is, just run the function before and after the execution of the code, and then find the difference between them.Example 2: Find the time taken for a code to execute....

big_O is a Python module to estimate the time complexity of Python code from its execution time. It can be used to analyze how functions scale with inputs of increasing size. big_O executes a Python function for input of increasing size N, and measures its execution time. From the measur...
