Python "Invalid Syntax" error while calling a function in IDLE

Question

I'm attempting to write a program that generates a random string of numbers, with its length based on user input. I wrote it in Sublime Text, and it worked perfectly with SublimeREPL, but I then took it into IDLE and attempted to run it and it threw an invalid syntax error.

import string
import random

# Random Number Password Generator


def digit_password(length):
    final = []
    while length > 0:
        final.append(random.choice(string.digits))
    length -= 1
    result = ''.join(final)
    return result


length = int(raw_input("How long will this password be? "))
print digit_password(length)

It always give me the invalid syntax error when I call the function, specifically the "digit_password" name. It worked in sublime text, but it wont work here in IDLE. Does anyone know why this is happening?

Im using the python 3.6.4 shell if that is relevant.

Answer 1

You have no brackets around the print call. Python 3 needs print to be constructed as print(item).

Change your last line to:

print(digit_password(length))

Ps. You might need to indent your return call.
