Python : Float object no iterable

Question

I have to calculate a equation that have a recursion. But if I am execute the code i get the failure that the Float object is not iterable

my code is:

def v(t, c):
    result = []
    if t == 0 or c == 0:
        return 0
    q = v(t - 1, c) - v(t - 1, c - 1)

    return max((0.2*(400-q)), (0.6*(400-q)), (1*(1200-q)), (0.85*(1115-q)), (0.87*(1127-q))) + v(t-1,c)

x = v(2, 1) print(x)

What can I do to get the result? Thank you

`max` takes an iterable, you pass it a `float`. The error message is quite to the point. What do you want the maximum of there when you pass a single value to the function? — user2390182, Dec 01 '17 at 06:59

You are using max(), but args in your function is a tuple (0.85 * (1115 - q)) + (0.87 * (1127 - q)), this is not right

in reality my code is: return max((0.2*(400-q)), (0.6*(400-q)), (1*(1200-q)), (0.85*(1115-q)), (0.87*(1127-q))) + v(t-1,c) i delete a part of the code to make it easier to understand – Serkan Kılınç Dec 01 '17 at 07:44

max() needs to be passed more than one argument and in your case only one argument is there which is causing the error. Try removing max or add one more results to your max() function to make it behave correctly.

def v(t, c):
    result = []
    if t == 0 or c == 0:
        return 0
    q = v(t - 1, c) - v(t - 1, c - 1)
    return ((0.85 * (1115 - q)) + (0.87 * (1127 - q))) + v(t - 1, c)

x = v(2, 1)
print(x)
