string at an index that does not exist in the string. The range of a string in Python is[0, len(str) - 1], wherelen(str)is the length of the string. When an attempt is made to access an item at an index outside this range, anIndexError: string index out of rangeerror is ...
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!
