Challenge: Retrieving Letters from String

Task

Swipe to start coding

You're given the string "This is string for learning" stored in the variable test_str.

Your task:

Create a variable first_char and assign it the value of the first character of the string test_str.
Create a variable last_char and assign it the value of the last character of the string test_str.
Create a variable highlighted_word and extract the word "learning" from the string test_str.
Use indexing to solve this task.
