Examples for string find in Python


I'm not sure what you're looking for, do you mean find()?

>>> x = "Hello World">>> x.find('World')6>>> x.find('Aloha');-1


you can use str.index too:

>>> 'sdfasdf'.index('cc')Traceback (most recent call last):  File "<pyshell#144>", line 1, in <module>    'sdfasdf'.index('cc')ValueError: substring not found>>> 'sdfasdf'.index('df')1


From the documentation:

str.find(sub[, start[, end]])

Return the lowest index in the string where substring sub is found within the slice s[start:end]. Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found.

So, some examples:

>>> my_str = 'abcdefioshgoihgs sijsiojs '>>> my_str.find('a')0>>> my_str.find('g')10>>> my_str.find('s', 11)15>>> my_str.find('s', 15)15>>> my_str.find('s', 16)17>>> my_str.find('s', 11, 14)-1
