callable object in python

Question

''' An array 'a' is divided into two
sub arrays 'b' and 'c' such that difference of the sums of elements in the respective
sub arrays is minimum
e.g a = [2,5,4,7,15,20]
b = [20,7,4]
c = [15,5,2]'''

a = [2,5,4,7,15,20]
b = []
c = []
while len(a) != 0:
val = a.pop(a.index(a(max)))
b.append(val)
val = a.pop(a.index(a(max)))
c.append(val)
print (b)
print (c)
print (sum(b)-sum(c))

......please someone fix the error

Answer 1

val = a.pop(a.index(a(max)))

👇

val = a.pop(a.index(max(a)))

Answer 2

I usually do silly mistakes
