Or Operator In Python

if 1==1 or 1==2:
    print("this is true")
#this is distinct from the || seen in some other languages

python logical operators code

using in as a logical operator in python

fruit = 'banana'
print('n' in fruit)     # Output: True
print('m' in fruit)     # Output: False
print('nan' in fruit)   # Output: True
if 'b' in fruit:
    print('Found it')   # Output: Found it
