Sum of values in Python, excluding equal values

Return the sum of 3 numbers, but if they're the same, they dont count towards the total. Can you help me find what's wrong in my code please?

def lone_sum(a,b,c):
    t=0
    if a==b and a!=c:
        t=a+c
    elif a==c and a!=b:
        t=a+b
    elif b==a and b!=c:
        t=b+c
    elif b==c and b!=a:
        t=b+a
    elif c==a and c!=b:
        t=a+b
    elif c==b and c!=a:
        t=b+a
    elif a==b and b==c:
        t=a
    return t

You can achieve it within two lines of code by using set like this

def lone_sum(a,b,c):
    return sum(set([a,b,c]))

This much more efficient than all the above codes. I suggested this because i believe programming is meant to solve problems efficiently.

def lone_sum(a,b,c):
    if a==b and a!=c:
        t=a+c
    elif a==c and a!=b:
        t=a+b
    elif b==a and b!=c:
        t=b+c
    elif b==c and b!=a:
        t=b+a
    elif c==a and c!=b:
        t=a+b
    elif c==b and c!=a:
        t=b+a
    elif a==b and b==c:
        t=a
    else:
        t = a + b + c
    return t
print (lone_sum(21, 32, 32))

There's nothing wrong with your code, I think you forgot to call the function. I also added some small features to your code.

A simpler solution:

def lone_sum(a, b, c):
    return sum({a, b, c})
