I have a function which returns either True or False. I'm trying to perform a loop where that function is called several times until it returns False, and count how many times it ran.
import random as rand
def test_function():
return rand.random > 0.5
count = 0
while test_function():
count += 1
print count
All this is doing is running it once though, and holding whatever value it got.
You forgot to actually call rand.random. Add () after it to do this:
return rand.random() > 0.5
Below is a demonstration:
>>> import random as rand
>>> rand.random
<built-in method random of Random object at 0x01DC02A8>
>>> rand.random()
0.4878133430124779
>>>
Right now, your code is testing if the function object itself is greater than 0.5.
True: >>> import random; >>> random.random > 0.5; TrueYou have to call the function with ().
return rand.random() > 0.5
python -c "from random import randint as r; print r(0,1)"or evenprint "mean count: 0.5":-)
