Python String Index() Method

Hello dear readers! Welcome back to another edition of our tutorial on Python. In this tutorial guide, we are going to be discussing about the Python String Index() method.

The Python string index() method determines if string str occurs in a string, or in a substring of a string if the starting index beg and ending index end are given. The method is the same as find(), but raises an exception if sub is not found.


The following below is the syntax for the Python String endswith() method -

str.index(str,  beg = 0,  end = len(string) )

Parameter Details

  • str - This specifies the string to be searched. 
  • beg - The is the starting index. By default its 0. 
  • end - This is the ending index. By default it is equal to the length of the string.

Return Value

This Python method returns an index if found, otherwise it raises an exception if str is not found.


The following below is a simple example -


str1 = "this is string example....wow!!!";
str2 = "exam";

print str1.index(str2)
print str1.index(str2, 10)
print str1.index(str2, 40)

Below is the output of the above example -

Traceback (most recent call last):
   File "test.py", line 8, in 
   print str1.index(str2, 40);
ValueError: substring not found

shell returned 1
