random.choice() not selecting all possibilities

random.choice() in Python does not work correctly.

I have the following function, but the following happens when called:

def Randomswitch():
    thechosenone = random.choice(range(0, 2))
    if (thechosenone == 0):
        return "WIN"
    if (thechosenone == 1):
        return "LOSE"

Randomswitch()

When Randomswitch is called it only returns WIN every time it’s called.

I am breaking my head trying to figure this out.

Can anyone help me please?

>Solution :

Seems to be working pretty well, have you tried only a few times? Let’s try 10,000 times and count the occurrences:

import random
from collections import Counter

def Randomswitch():
    thechosenone = random.choice(range(0, 2))
    if (thechosenone == 0):
        return "WIN"
    if (thechosenone == 1):
        return "LOSE"

Counter(Randomswitch() for i in range(10000))

output:

Counter({'LOSE': 4980, 'WIN': 5020})

Seems pretty decent 😉

improving the code

That said, you code can be improved, why don’t you just pass the values to chose from to random.choice?

def Randomswitch():
    return random.choice(['WIN', 'LOSE'])
