How do you square in Python?

There are several ways to square a number in Python:

  1. The ** (power) operator can raise a value to the power of 2. For example, we code 5 squared as 5 ** 2.
  2. The built-in pow() function can also multiply a value with itself.
  3. And, of course, we also get the square when we multiply a value with itself.
