What is a trailing space?

I'm trying to do the input challenge, when i submit my code it, it says to add in a trailing space. What is that?

age = input("What is your age?")

You need to add a trailing space between the question mark and the final parenthesis.

try this.

age = input("What is your age? ")

You need a space after the question mark.

Currently if the user inputs, it will look like this:

What is your age?28

To put a space between user input and the message, you have to explicitly put it after the question mark.

To fix your code, just do the following:

age = input("What is your age? ")

Notice the space after the question mark. Now when the user inputs it looks much nicer:

What is your age? 28

(28 isn't my age it's just a random age)

Good luck! ~alex
