Do you want to learn how to automate tests in Python? Python is one of the best languages for test automation because it is easy to learn, concise to write, and powerful to scale. These days, there’s a wealth of great content on Python testing. Here’s a brief reference to help you get started.
If you are new to Python, read How Do I Start Learning Python? to find the best way to start learning the language.
If you want to roll up your sleeves, check out Test Automation University. I developed a “trifecta” of Python testing courses for TAU with videos, transcripts, quizzes, and example code. You can take them for FREE!

I’m a big fan of PyHamcrest, an assertion library. I’ve contributed to it myself. https://pyhamcrest.readthedocs.io/
For mocking out external dependencies, I use Mountebank – mbtest.org – for which I’ve written a Python wrapper – https://mbtest.readthedocs.io/
