How to use rindex() to find last occurrence of substring In Python
rindex() method returns the last occurrence of the substring if present in the string. The drawback of this function is that it throws the exception if there is no substring in the string and hence breaks the code.
Python3
# Python3 code to demonstrate # Find last occurrence of substring # using rindex() # initializing string test_string = "GfG is best for CS and also best for Learning" # initializing target word tar_word = "best" # printing original string print ( "The original string : " + str (test_string)) # using rindex() # Find last occurrence of substring res = test_string.rindex(tar_word) # print result print ( "Index of last occurrence of substring is : " + str (res)) |
Output
The original string : GfG is best for CS and also best for Learning Index of last occurrence of substring is : 28
