+##A First Attempt at PyTest Fixtures and Parametrization (using PyCharm)
+
+![Python version][python-version]
+
+I found the #100daysofcode tutorials shown using Vim quite difficult to follow. 
+
+So I looked online for other turtorials knowing to look for pytest fixtures and parametrization.
+
+The tutorial I have used for this is taken directly from the [PyCharm 2019.1 help files](https://www.jetbrains.com/help/pycharm/pytest.html)
+
+This challenge served two purposes for me:
+1. Follow a very simple pytest tutorial using PyCharm
+2. Complete my first ever Pull Request.
+
+I intend on writing a more advanced PyTest so will issue another PR against this submission later. 
+
+When I've finished the #100daysofcode I'll read Python Testing with Pytest by Brian Okken. TDD looks interesting and I'm keen to learn more!
