I think my code is right but it is not getting accepted. Can anyone help me figure out what is wrong ?

The python code is as follows:

n=input()
sum1=0
sum2=0
for i in range(0,3):
    sum1=sum1+(int(n[i]))
for i in range(3,6):
    sum2=sum2+(int(n[i]))
if(1==(abs(sum1-sum2)) or 0==sum1-sum2):
    print("Yes")
else:
    print("No")


Pls help me solve the issue
