Comparison operators

Definition

Comparison operators are used to compare two values and return a Boolean result (True or False). They are fundamental in decision-making constructs such as if statements.

5 Must Know Facts For Your Next Test

1. The six main comparison operators in Python are ==, !=, >, <, >=, and <=.
2. Comparison operators can be used to compare both numbers and strings.
3. The equals operator (==) checks if two values are the same, while the not equals operator (!=) checks if they are different.
4. The greater than (>) and less than (<) operators compare numerical values for magnitude.
5. Comparison operators can be combined with logical operators for more complex conditions.
