random.choice() takes two positional arguments, but three were given.

[ShakeyPakey]

Hello.

In Python, I am using the random module. I have used the random.choice() method to randomly pick from two strings:

    import random

    variable = random.choice('string1','string2')
    print(variable)

However, when I run it, the following error occurs:

Error:
TypeError: choice() takes two positional arguments, but three were given.

I have also used

from numpy import random

instead of just

import random

but it still does not work.

How am I able to fix this error? Thank you.
