Python Code Testing using profilers


Jackson Isaac


This talk will cover about how we can profile python code using line_profiler and improve the code.

After this talk, the audience will have a clear view about code profiling, understanding it’s output and how can we improve our code and comparing the results.


The audience will learn about line_profiler, it’s use in Software Development and how it helps in making the software efficient by calculating the Time used by the modules and each instructions under them.

The talk will show how we can use line_profilers with Python by testing it live on a demo application written using pygtk and how to analyze the results and optimize the code.

Talk Outline:

Introduction to Python profilers.
History of line_profiler
How to install line_profiler, using pip and from source (for Mac users).
Adding decorator to the code for profiling.
Steps to run profiler and how to check the profiled output.
