Please like the video if it helps you :)

Simple python example and short video to illustrate how "or", "and" and "not" operator works. It uses very simple example to focus on how various logical operator are used with "if" to handle multiple test conditions. The values of variables are changed to show different scenarios where the logical operator may returns True or False outcome. This video uses only 2 test conditions to illustrate the concept but it can be used with more than 2 test conditions

"or" operator returns True when ANY of the test conditions returns True.
"and" operator returns True only when ALL of the test conditions return True
"not" operator is to flip the boolean result. It is usually used to test when some condition is False.
like "if not(isWeekend)" is testing when isWeekend is False.
It is actually same as "if (isWeekend == False)"

This video also include an example of common mistake made with the "or" operator by beginners.
The wrong syntax seems intuitive to use but is actually not a properly test condition.

After understanding how logical operator works with "if", you can also look at the difference between "if" and "while".
Many beginners get confused with "if" and "while" as their syntax and mechanism are very similar. "while" works like a repeated "if"
statements and due the repeating nature, it is known as a loop.
