The "if" keyword in list comprehensions (vs the normal if - else)
A special place use of the "if" keyword in Python is within list comprehensions. This so-called "guard" serves to select what elements of the original list or other iterable will be added to the comprehension; it works as a kind of filter. This form of the "if" statement is never followed by an "else". For more information, see the notebooks below (notebooks will open on Google Colab - no installation required)
