## Comparison and Logical Operators in Python

The comparison operators returns a boolean either True or False.

Assuming that x=10 and y=20, the result of the operations is also given in following table:

Operator Description Example
> True if the left operand is higher than the right one >>> x>y
False
< True if the left operand is lower than right one >>> x<y
True
== True if the operands are equal >>> x==y
False
!= True if the operands are not equal >>> x!=y
True
>= True if the left operand is higher than or equal to the right one >>> x>=y
False
<= True if the left operand is lower than or equal to the right one >>> x<=y
True

## Logical Operators in Python

The following keywords in Python combine two Boolean expressions. They are called logical operators. Two operands should have Boolean value True or False. Assuming that x=True and y=False.

Operator Description Example
and True if both are true >>> x and y
False
or True if at least one is true >>> x or y
True
not Returns True if an expression evalutes to false and vice-versa >>> not x
True

Comparison and logical operators are useful in controlling flow of program.
