Check String

Very often it hits that we need to check for the presence of some character or word in the string, and in order to realize this, we should use such a key word as in. As a result, we get a boolean value: True if such a character or substring is present in the string, and False - in the opposite case. For a better understanding, let's look at an example.


              123
            
string = 'Pear Lime Banana'
print('Lime' in string)
print('Mango' in string)
