Make your code listen

The big little idea

input() asks for information and gives it back as a string. Your program can use that answer to do something personal or surprising.

color = input()
print(f"One {color} spaceship, coming up!")

In this playground, type answers into the Program input box before running. Each call to input() takes the next line. Even an answer like 12 arrives as text; int() changes a whole-number string into a number.

Predict, then try: read the example from top to bottom. What do you think it will print? Copy it into the editor below to test your prediction.

Your turn, code explorer.

Read a nickname from input and print Welcome aboard, Captain Nova! when the input is Nova.

Output goal

Welcome aboard, Captain Nova!

Your code

nickname = input()
print(f"Hello, {nickname}!")

Edit the code. Then run it. Ctrl / ⌘ + Enter also works.

The first run loads Python. This can take a moment.

Program input For programs that use input()

Answers, one per line, in the order your program asks

Add answers before you run. Each input() reads the next line. Use made-up names and details.

A little hint, please

Keep {nickname} inside an f-string. Change the words around it to match the goal.

Show one possible solution

There can be more than one way. Read this version, then try writing it yourself.

nickname = input()
print(f"Welcome aboard, Captain {nickname}!")

Pack this idea for later: Input lets the person using your program change what happens.
