What is the use of Timeit?

Well, how about using a simple time module? Just save the time before and after the execution of code and subtract them! But this method is not precise as there might be a background process momentarily running which disrupts the code execution and you will get significant variations in the running time of small code snippets. Timeit runs your snippet of code millions of times (default value is 1000000) so that you get the statistically most relevant measurement of code execution time! Timeit is pretty simple to use and has a command-line interface as well as a callable one....

Python Timeit() Syntax:

Syntax: timeit.timeit(stmt, setup, timer, number) Parameter: stmt which is the statement you want to measure; it defaults to ‘pass’.setup which is the code that you run before running the stmt; it defaults to ‘pass’. We generally use this to import the required modules for our code.timer which is a timeit.Timer object; it usually has a sensible default value so you don’t have to worry about it.the number which is the number of executions you’d like to run the stmt.Returns the number of seconds it took to execute the code....
