TypeError: 'float' object is not iterable when I'm using WHILE

Question

Hello, I'm trying to make a simple iteration to get 1000 vectors to used them in another calculation, I >have tried many things but still I'm getting this error of "float" object is not iterable when I'm >using while. Here is my script:

import random
count = 1000
alfa_1 = [0, 1]
alfa_2 = [0, 1]
d = [0, 1]
while count > 0:
    print count
    for i in range(count):
        alfa_1 = random.random () * (max (alfa_1) - min(alfa_1)) + min (alfa_1)
        alfa_2 = random.random () * (max(alfa_2) - min(alfa_2)) + min (alfa_2)
        d = random.random () * (max(d) - min(d)) + min(d)
        paramvect = [alfa_1, alfa_2, d]
        print paramvect
        count = count - 1

Thanks for any help you can provide!

You initially assign alfa_1 and alfa_2 list values, but later assign them to float values.

# As lists
alfa_1 = [0, 1]
alfa_2 = [0, 1]
...
# As floats
alfa_1 = random.random () * (max (alfa_1) - min(alfa_1)) + min (alfa_1)
alfa_2 = random.random () * (max(alfa_2) - min(alfa_2)) + min (alfa_2)

Consequently, on the second iteration of the loop, you pass max a float when it expects something iterable (like a list). (It's not clear what the goal is here so I can't offer a more complete solution.)
