rfind() : Find the rightmost matching of the search string and return the position in Python

Returns the rightmost matching position of the search string in a main string

main_string.rfind(search_string, start, end)

search_string : Required, String to be searched and position is returned if found.
start : Optional, Starting position of search , by default it is from 0 or starting position of string
end : Optional , ending position of search, by default it is end of the string.

my_str='Welcome to plus2net.com Python section'
output=my_str.rfind('co') 
print(output) # output is 20

Using optional parameters start and end. If not matching is found then output is -1

my_str='Welcome to plus2net.com Python section'
output=my_str.rfind('co',10,21)
print(output) # output is -1

my_str='Welcome to plus2net.com Python section'
output=my_str.rfind('co',10,22)
print(output) # output is 20

rindex() method raise an exception if searched string is not found but rfind() returns -1 if searched string is not found. That is the main difference between rfind() and rindex()
