Contains in python
The _contains_() method in Python checks if a string contains a specific substring and returns True if it does and False if it doesn’t. It is case sensitive, meaning that it treats uppercase and lowercase letters as different characters.
a = 'xyz'
print('a contains x =', a.__contains__('x'))
print('a contains B =', a.__contains__('B'))
print('a contains T =', a.__contains__('T'))
output:
a contains x = True
a contains B = False
a contains T = False
