Impara Boolean Data Type in Python | Conditional Statements in Python

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:


              123456
            
# Check if `1` equals `1`
print(1 == 1)
# Check if `"abc"` equals `"aBc"`
print("abc" == "aBc")
# Check if `87*731` greater than or equal to `98*712`
print(87*731 >= 98*712)

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.

Now, let's evaluate the following:

Is first_integer variable less than or equal to second_integer? (It must return True if the first variable is less than or equal to the second, and False if it is greater than the second)
Is the string "text" not the same as "TEXT"?
Does the string length of "Python" equal 6?

Note

Printing an expression such as variable_1 >= variable_2 doesn't imply that variable_1 is genuinely greater than or equal to variable_2. It simply signifies that you're evaluating whether this statement is True or False. This operation does not alter the values of the variables in any manner.
