Tutorial 3/15
The Basics
Python: Input
Interact with your users by capturing data from the keyboard.
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 instantly in a variable box.

Question & Answer
See how we ask a question and save the user's response.
name = input("Who are you? ")
# Ask question, wait for answer
print("Hello " + name)
# Join greeting with their name
Tracing
Predict
If I type "Red" when prompted, what appears?
color = input("Fave color? ")
print("I like " + color)
print("I like " + color)
