I have Python 2.7.6 on my Mac OSX. I am trying to include random module in my python script which is not working.

If you see above, import random works fine on python prompt. But as soon as I run my script :( it can't find random module and after that I can not import random on python prompt as well.
My script is having #!/usr/bin/python as the first line.

import os
import sys

from random import random

class generate_random_no:
    def __init__(self):
        #rand = random()
        pass
    def get_random_number(self):
        return randint()

    def get_random_number(self, upperbound):
        return randrange(upperbound)

Avoid filename like random.py. It will shadow standard library module random.
