From the lesson: 50 Python Practice Problems with Instant Answer Checking (Beginner to Advanced)

Fifty problems, each with a code editor and real tests. Write your solution, press Check, and see exactly which cases pass. Stuck? Hints reveal one at a time, and the solution unlocks once you have checked at least once. Your code and progress are saved in this browser.

Read the lesson

Write caesar(text, shift) that shifts every letter by shift places, wrapping around the alphabet. Keep the case, leave everything that is not a letter unchanged, and allow negative shifts (which decode).

caesar("Hello, World!", 3)  ->  "Khoor, Zruog!"
def caesar(text, shift):
pass
Solution unlocks after your first Check

What Check runs

Your code runs first, then each of these lines. The output must match exactly.

RunsExpected output
caesar("Hello, World!", 3)'Khoor, Zruog!'
caesar("xyz", 3)'abc'
