But if you are using Python, we have an inbuilt module to generate all valid permutations for the given object. By using our site, you After sorting, both will become afi after sorting. All substrings of string are : [‘G’, ‘Ge’, ‘Gee’, ‘Geek’, ‘Geeks’, ‘e’, ‘ee’, ‘eek’, ‘eeks’, ‘e’, ‘ek’, ‘eks’, ‘k’, ‘ks’, ‘s’]. Don’t stop learning now. There is no dedicated function in Python to find the substring of a string.But you can use slicing to get the substring. Finding substring in a string is one of the most commonly faced problem. By using our site, you Input: str = google Output: e l g o oo goog A simple solution would be to generate all substrings of the given string and print substrings that are palindrome. This particular task can also be performed using the inbuilt function of combinations, which helps to get all the possible combinations i.e the substrings from a string. Even though you may see characters on your screen, internally it is stored and manipulated as a combination of 0s and 1s. Attention geek! Python Substring.

Then the 2nd loop would go through all possible lengths of the substring (from that letter to the end, or less). In this tutorial, we will look into various operations related to substrings.
