- In mathematics, the and operation returns true only if both the

operands evaluate to True. Otherwise the and operation returns False.

- In Python the and operator returns the first operand if the first operand evaluates to False. Otherwise it returns the second operand.

- The and operator in Python is a short circuit operator. That is the second operator will be evaluated by the and operator only if the first operand evaluated to True.

Truth Table for the 'and' operator:

Operator1	Operator2	Result

Ven Diagram for the operator 'and':

The Ven diagram of the and operator is given below.

This Ven diagram is about a search criteria stating the search results should include News that is only about Europe.

Example 1:

signal = "Green"

path = "Pedestrian walking"

if signal is "Green" and path is "clear":

print("All clear and Going")

else:

print("Can not go")

print("Reason:%s"%(path))

Output 1:

Can not go

Reason:Pedestrian walking

Example 2:

filter1 = True

filter2 = True

if filter1 is True and filter2 is True:

print("Printing Search Results")
