Relational Operators
Relational operators are used to compare two values or expressions. They are also known as
Comparison operators. The result of these operators is either True or False.

Example
Operator Name Description Output
(X = 9, Y = 6)

If the values compared are equal, returns
== Equal to X == Y False
True, else returns False.

!= Not equal to If the values compared are unequal, X != Y True
returns True, else returns False.
Greater If the first value is greater than the
> X > Y True
than second, returns True, else returns False.

< Less than If the first value is less than the second, X < Y False
returns True, else returns False.
Greater If the first value is greater than or equal
>= than or to the second, returns True, else returns X >= Y True
equal to False.
Less than or If the first value is less than or equal to the
<= X <= Y False
equal to second, returns True, else returns False.
Logical Operators
Logical operators are used to combine two or more expressions containing relational operators.
These operators evaluate to either True or False. These are used to test conditions and control the
flow of a program based on the result of the condition.
Example
Operator Description Output
(X = 9, Y = 6)

If both expressions evaluate to True, returns True, else
and returns False. (X > 5) and (Y > 4) True

If any one of the expressions evaluates to True, returns
or (X > 5) or (Y > 10) True
True, else returns False.

If expression evaluates to True, returns False, and vice-
not not(X > Y) False
versa (reverses the result of the expression).
