In Python we can use the find() and index() methods to get the index of the first occurrence of the substring in a string. Python provides various string manipulation functions to modify and access text data. In
To get the index of a character in a python string, we can use the built-in method. Here is an example that gets the character index in…
2. Get Substring of a String using Slicing Slicing is a built-in Python feature that allows you to extract a substring from a string by specifying its start and end indices. The resultingstringwill include all the characters from the start index up to, but not including, the end index. ...
As the first step, we will create a sample string list named my_list to use in the following examples.my_list = ['a', 'b', 'c', 'd', 'e'] print(my_list) # ['a', 'b', 'c', 'd', 'e']Let’s see how to retrieve the first index in our list!

In the following program, we have list of strings, and we shall find all the occurrences of the stringmangoin the list. The logic is that, each time we get the index of element in the list, we slice the list from that index and find the next occurrence of the element. We collect ...
