How to Combine Conditions in Python

In Boolean logic, two fundamental operators are OR and AND. The OR operator returns True if at least one of the conditions is true; otherwise, it returns False. The AND operator returns True only if both conditions are true; otherwise, it returns False. You can combine conditions using the and and or operators (always in lowercase)

• condition1 and condition2 yields True only when both conditions are True;
• condition1 or condition2 gives True if at least one condition is True.

Note

You can also chain multiple conditions using these operators. Use parentheses to make the order of operations clear.

For example, consider the following conditions:

1. Whether 2 is greater than 1 and "bbb" is different from "aaa".
2. Whether the character at index 2 in the string "my string" is either "y" or "s".

The first print() returns True since both 2 > 1 and 'bbb' != 'aaa' are true. The second print() outputs False because the character at index 2 is neither 'y' nor 's' (it's actually a space).

Note

To reverse a boolean value, use the not operator. For example, not 1 == 1 results in False because 1 == 1 is True, and not negates it to False..
