sys.executable python 2.7 vs 3.6

[mcmxl22]

This web.py script runs fine in both 2.7 and 3.6.

import webbrowser

def websites():
    new = 2
    choice = input('Type site name:\n> ') # I have raw_input here to run in 2.7
    site = choice
    url1 = 'www..com'
    url = 'http://' + url1[:4] + site + url1[4:]
    webbrowser.open(url,new)

if __name__ == "__main__":
    websites()

I do have both programs in the same directory so I don't know why the one won't open the other in 3.6.
