Presumably you must do this without Python's min function?

What would be the point? Your code already does that.

The last if is not needed.
Forced to pretend that there is no min function already, I'd be tempted
to write
def min3(a, b, c):
def min2(x, y):
return x if x < y else y;
return min2(a, min2(b, c))
