String Indexing in Python

String indexing allows you to access individual characters of a string using their position, or index.

Indexing in Python starts from 0. That means the first character of any string has index 0, the second character has index 1, and so on.

For example, in the word "codefinity":

To access a character by index, use square brackets [] with the index number inside:

12345
string = "codefinity" print("Print the c symbol:", string[0]) # First character print("Print the o symbol:", string[1]) # Second character print("Print the y symbol:", string[9]) # Last character
copy

Index Out of Range

If you try to access a character at an index that does not exist, Python will raise an error:

12
# This will raise an IndexError print(string[10])
copy

This is called an "index out of range" error. In the word "codefinity", valid indexes are from 0 to 9, because it has 10 characters in total.

In accounting systems, initials are often used instead of full names when generating reports or signatures.

You are given the variables first_name and last_name, which store a person’s name.

Use string indexing only to extract the first letters from each name and display them in the format: M.J.
