Python: Relational Operators

Now that we’ve added if statements to our repertoire for developing control flow, let’s look at some additional techniques for creating boolean expressions. While we have discussed two relational operators thus far, equals and not equals, there are four more:

  • > greater than
  • < less than
  • >= greater than or equal to
  • <= less than or equal to

Let’s take a look at an example that shows how this could be used to determine if a student has passed the class or not:

grade = 75

if grade >= 65:
    print("You passed the class!") # This will print.
if grade < 65:
    print("See you in summer school!") # This will not.

Notice that it would be mathematically impossible for both print statements to execute at the same time.
