Python String rfind() Method



Hello guys! Welcome back to another section of my tutorial on Python. In this tutorial guide, we are going to be discussing about the Python String rfind() method.

The Python string rfind() method returns the last index where the substring str is found, or -1 if no such index exists, optionally restricting the search to [beg:end].

Syntax

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

obj.rfind(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

Returns the last index if found, otherwise -1.

Example

The following below is a simple example -

#!/usr/bin/python

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

print str1.rfind(str2)
print str1.rfind(str2, 0, 10)
print str1.rfind(str2, 10, 0)

print str1.find(str2)
print str1.find(str2, 0, 10)
print str1.find(str2, 10, 0)

Output
Below is the output of the above example -

5

-1
