Unable to run simple "if__name__ =='__main__':" syntax using Canopy

Question

I obtained the following password generator (Test.py) from the Internet and I thought it would be easy to run in Canopy but it does not seem to work at all.

I get invalid syntax errors all the time. I send the code to a colleague of mine and she said it worked fine using the simple i-Python terminal on her Linux Machine.

#!/usr/bin/env python
import random
import sys
import string


def main(argv):

    if (len(sys.argv) != 5):
        sys.exit('Usage: simple_pass.py <upper_case> <lower_case> <digit> <special_characters>')

    password = ''

    for i in range(len(argv)):
        for j in range(int(argv[i])):
            if i == 0:
                password += string.uppercase[random.randint(0,len(string.uppercase)-1)]
            elif i == 1:
                password += string.lowercase[random.randint(0,len(string.lowercase)-1)]
            elif i == 2:
                password += string.digits[random.randint(0,len(string.digits)-1)]
            elif i == 3:
                password += string.punctuation[random.randint(0,len(string.punctuation)-1)]

    print 'Your new password is: ' + ''.join(random.sample(password,len(password)))

if __name__ == "__main__":
    main(sys.argv[1:])

I tried:

$python Test.py 2 2 2 2

I tried using the entire pathname as well, but nothing seems to work! I'm quite frustrated because it seems like it would be so easy. Any help would be greatly appreciated.

Answer 1

My guess is that you're running this command inside of ipython

$ python Test.py 2 2 2 2

Which is how you would run the script if you were in the command line, and it's comming back with the error:

In [1]: python Test.py 2 2 2 2
  File "<ipython-input-3-5bade39d33f0>", line 1
    python Test.py 2 2 2 2
                                           ^
SyntaxError: invalid syntax

If you want to run it inside of Canopy (which is an ipython shell, not a terminal window), run the file like so

In [1]: %run Test.py 2 2 2 2
Your new password is: NDt1q.+1
