Code not working in terminal

Hey! My code isn't working in terminal but it runs in the workspace, any tips?

import random
words = [
    'melon', 
    'Lemon', 
    'berry', 
    'blueberry', 
    'strawberry', 
    'apple', 
    'banana', 
    'lime', 
    'grapefruit'
]

while True:
    start = input('Press enter to start or enter Q to quit. \n')
    if start.lower() == 'q':
        break
    else:
        print('Have fun!')

If you type python --version in the Console (or Terminal, Command Prompt, etc), you get the version of Python.

On Treehouse Workspaces it will return "3.x.x" where the X's are other numbers, in your console by default will return "2.x.x".

Python 2 (your computer's defualt) and Python 3 (Workspace's default) are pretty different.

Main differences are listed here:

  • Python 2 has print as a keyword, not a function. This means in Python 2 your would print without parentheses and in Python 3 will need parentheses.

Examples:

# Valid in Python 3
print("Hello")

# Valid in Python 2
print "Hello"

  • The very important difference that confuses lots of beginners is the input function. In Python 3 by default it turns the input into a string. If you type in something into your program in this example "hello", Python 2 actually will look for a variable called hello.

  • And there are many more differences.

So about that second difference I listed, it important.

To fix your problem, either use the function raw_input instead of input or install Python 3 and type in:

python3 your_file.py

instead of:

python your_file.py

Try doing either of those :)

Good luck! ~alex
