Data Types in Python

##   Introduction to Boolean Data Type

The boolean data type is a semblance of our ordinary words: yes or no. Number `1` means yes, and `0` means no. It was invented to give certain instructions to computers. For instance, if this condition is true, we should continue, but in the opposite case, we should stop. Indeed, it is better to use only `0` and `1` to exclude misunderstanding, but every number except `0` means `True`.

It should be noted that if we write true instead of `True` or false instead of `False`, it leads to an error.

The operators `>`, `<`, `!=`, `==`, `<=`, and `>=` are essential for making meaningful boolean statements. Without these symbols, boolean statements wouldn't serve any purpose.

 Sign Syntax Purpose > X > Y Returns True if X is greater than Y < X < Y Returns True if X is less than Y != X != Y Returns True if X is not equal to Y == X == Y Returns True if X is equal to Y <= X <= Y Returns True if X is less than or equal to Y >= X >= Y Returns True if X is greater than or equal to Y

Let's look at the example of simple boolean statements:

The following expressions return `True`:

However, these expressions return `False`:

Choose the correct sign from `>`, `<`,`!=`, `==`, `<=`, and `>=` to fill in the gaps `___` and to make all statements return `False`.
