I want to solve the problem that there is a TypeError in while and the process is not progressing.

I'd like to do a binary calculation using half-add and full-add, but an error appears below the last while syntax, and the process does not proceed.Please let me know

error messages:

TypeError Traceback (most recent call last)

     42 fa = int(b(k))
     43 A, keta = fa(a, b, x)
TypeError: 'str' object is not callable

code:

  A = a * b

     else:
        A = 0

  A1,keta1 = ha(a,b)
  A,keta2 = ha(A1,x)
  keta=OR (keta1, keta2)
  return A, keta

As a whole, there are about three major mistakes.

Extraction of Elements

while k>=0:
  ha = int(a(k))
  fa = int(b(k))
  A,keta=fa(a,b,x)

a[k], b[k] if you want to take it out

ha, fa are used as function names, so they are overwritten.Should be a different variable name
The value specified for the function fa should be the previous "extracted value" instead of a, b

We have made it possible to calculate even if the number of digits a and b are different from the corrections pointed out by those who have already answered.You can also fill in 0 to make it the same number of digits before calculating.

def AND(x,y):
    return1 if x and else0

defOR(x,y):
    return1 if x or else0

def NOT(x):
    return1 if not x else0

def ha(x,y):
    K = AND(x,y)
    A = AND (OR(x,y), NOT(K))
    return A,K

deffa(x,y,z):
    A1,K1 = ha(x,y)
    A2,K2 = ha(A1,z)
    K3 = OR (K1, K2)
    return A2,K3


a = input("binary a:")
b = input ("binary b:")

k, m = len(a), len(b)
keta = 0
goukei='"
while > 0 or m > 0:
    k,m = k-1,m-1
    na = 0 if k < 0 else int(a[k])
    nb = 0 if m<0 else int(b[m])
    ns,keta=fa(na,nb,keta)
    goukei=str(ns)+goukei

goukei=('1'if keta else') + goukei
print(f'{a}+{b}={goukei}')

binary a:110011
Binary b: 1110
110011 + 1110 = 1000001
