Answer -
The method index( ) determines if string str occurs in string or in a substring of string if starting indexbeg and ending index end are given. This method is same as find( ), but raises an exception if
sub is not found.
Syntax
str.index(str, beg=0 end=len(string))
Example
# !/usr/bin/python
str = “this is string example….wow!!!”;
str = “exam”;
print str.index(str);
print str.index(str, 10);
print str.index(str, 40);
OUTPUT
15
