why Python and lua have not ++ and --?

Question

I thought Python and lua are Writed by C language,and most depended on macro in c.
eg:
#define max(A,B) ((A)>(B)?(A):(B))
x= max(2*y,z/1.73);
after preprocess,it becomes
x=((2*y)>(z/1.73)?(2*y):(z/1.73);
if z++ replace z,z will ++ twice

can anyone tell me the real reason why Python no ++ and --?
