Python program that demonstrates the use of Membership operators:
# Define a list and a string
fruits = ['apple', 'banana', 'cherry']
text = 'Hello, World!'
# Using the 'in' operator
print('apple' in fruits) # True
print('grape' in fruits) # False
print('World' in text) # True
print('world' in text) # False
# Using the 'not in' operator
print('apple' not in fruits) # False
print('grape' not in fruits) # True
print('World' not in text) # False
print('world' not in text) # True
Output
True False True False False True False True
