How to measure python execution time using the Timeit module

In this quick tutorial, I display how to practically use the built in Python Timeit module to test the execution time of snippets of code.

This can be very useful when for example you want to measure how quickly a JSON serialization library can serialize a test response.

Thank you for your explanation of this!

u god, with the lambda addition I could use the timeit. Thanks.

[henrikasvaranauskas]

it slows down the execution time by a factor of like 100. any idea why?

Thanks this worked for me. Why does it only work when I put lambda in front of the function i'm testing? Otherwise I get an error.
