How do I check if a given Python string is a substring of another one? [duplicate]
I have two strings and I would like to check whether the first is a substring of the other. Does Python have such a built-in functionality?
Solution 1:
Try using in like this:
>>> x = 'hello'
>>> y = 'll'
>>> y in x
True
Solution 2:
Try
isSubstring = first in theOther
Solution 3:
string.find("substring") will help you. This function returns -1 when there is no substring.
