Often, we need to check if two values are equal.

To do this we use this instruction called equals which is written in code as ==

It is made of two equals signs which is confusing as we already use one equals sign as the assignment instruction.

The == instruction is like the + or - math instructions, but it returns a boolean value of True if the values are equal and False otherwise.

Here is an example:

The equals instruction == is between between the two values it needs to check. It is substituted with the result of the check. So in this case, 3 == 4 is replaced by False and the if statement uses that value to make a decision.

Remember, the single equals is for assigning a value to a variable, and a double equals is for checking a value.

This is the same code, but we check if 3 equals 4 and assign the result to a variable, then that variable is substituted in the if statement check.

The equals instruction also works on different types
