Python String contains
Python string __contains__()
is an instance method and returns boolean value True or False depending on whether the string object contains the specified string object or not. Note that the Python string contains() method is case sensitive. Let’s look at a simple example for string __contains__() method.
s = 'abc'
print('s contains a =', s.__contains__('a'))
print('s contains A =', s.__contains__('A'))
print('s contains X =', s.__contains__('X'))
Output:
s contains a = True
s contains A = False
s contains X = False
We can use __contains__() function as str class method too.
print(str.__contains__('ABC', 'A'))
print(str.__contains__('ABC', 'D'))
Output:
True
False
Let’s look at another example where we will ask the user to enter both the strings and check if the first string contains the second string or not.
input_str1 = input('Please enter first input string\n')
input_str2 = input('Please enter second input string\n')
print('First Input String Contains Second String? ', input_str1.__contains__(input_str2))
Output: Please enter first input string JournalDev is Nice Please enter second input string Dev First Input String Contains Second String? True
