This post explains how to use if statements in Python. This will form the backbone of much of your code going forward! Else statements, nesting, + more.

elif is the Python else-if statement. It allows one to check multiple expressions for truth value and execute a block of code as soon as one of the conditions evaluates to true.

While Python has lacked a native syntax for pattern matching, it has been possible to emulate it with if/elif/else chains or a dictionary lookup.
