Introduction to Python

Boolean Data Type

Welcome to section three! In this section, we'll dive into another Python data type: the boolean or logical type. Booleans can only have one of two values: True or False. This data type comes into play when evaluating logical conditions.

Here are the logical operators for comparison:

== equal to;
!= not equal to;
> greater than;
< less than;
>= greater than or equal to;
<= less than or equal to;

When you apply these operators, the result will be a boolean value: True if the condition is met, and False if it isn't. For instance, consider the following evaluations:

What do the results above signify? The first True indicates that 1 is equal to 1 (which is self-evident); the second False suggests that the strings "abc" and "aBc" differ due to the case sensitivity of the letter 'b'. The final False implies that 87*731 isn't greater than or equal to 98*712. In fact, 63597 is less than 69776.

Task

Now, let's evaluate the following:

Is 765*43 less than or equal to 456*78?
Is the string "text" not the same as "TEXT"?
Does the string length of "Python" equal 6?

Everything was clear?
