Time to get started on Python homework...

range(1, 50) creates a range from [1, 50)

Here's a more Python noob-friendly way of doing it.

Code:

import random

randomNumbers = []
while len(randomNumbers) < 6:
    randomNumber = random.randint(1, 49)
    if randomNumber not in randomNumbers:
        randomNumbers.append(randomNumber)

for eachRandomNumber in randomNumbers:
    print(str(eachRandomNumber) + " ")

Yeah, that'll probably make my teacher less hard, thus less suspicious. Looks like something I would come up with, thanks Fiel
