Card 3: Input

Module 1: The Basics

1 The Hook

If print() is the Megaphone (Output), then input() is the Microphone (Input).

It pauses the program and opens a "listening ear" to wait for the user to type something. Whatever they type gets stored in a variable.

2 Worked Example

See how we ask a question and save the answer.

name = input("Who are you? ") # Ask question, wait, and save answer in 'name'
print("Hello " + name) # Join "Hello " with the answer

PREDICT

If I type "Red", what happens?

color = input("Fave color? ")
print("I like " + color)
