Logical operators 

The Logical operators that we can perform in python are:

1. Logical AND (&&)
2. Logical OR (||)
3. Logical NOT (!)

Logical AND (&&)

The logical AND operator returns True if both the statements are True else returns False.

a=55
if(a&gt50 and a&lt100):
    print("a lies between 50 and 100")

Output

a lies between 50 and 100

Logical OR (||)

The logical OR operator returns true if any one of the statements are true and false if both the statements are false.

a=50
if(a&gt0 or a&lt0):
    print("a is either positive or negative")
else:
    print("a is zero")

Output

a is either positive or negative

Logical NOT (!)

Logical NOT operator is performed only on single expression. It converts True value to False and False value to True.

a=0     
if(a!=0):
    print("a is either positive or negative")
else:
    print("a is zero")

Output

a is zero
