It's actually cleaner to use logging as you won't have to go through all your code to remove the print statements. In this tutorial […]
List comprehensions in Python are very handy. They can also be a little hard to understand when and why you would use them. List comprehensions tend to be harder to read than just using a simple for loop as well. We'll spend some time looking at how to construct list comprehensions and learn how they […]
