This code iterates over a list of strings ["a", "b", "c"] and prints a formatted message for each element in the list. Here's a breakdown:

1. for letter in ["a", "b", "c"]: - This indicates a loop that will iterate through each element of the list ["a", "b", "c"]. During each iteration, the current element is assigned to the variable letter.

2. print(f"This letter is {letter}") - This prints the string "This letter is " followed by the current value of the letter variable. The f in front of the string denotes an f-string, which allows inserting variables or expressions into curly brackets {} within the string.

Output:

For the list ["a", "b", "c"], the loop will print:

This letter is a
This letter is b
This letter is c
