Bad Programming Practices

Each post must contain one bad programming practice to add to the list. I'll start:

In C++, overload library functions by using #define. That way it looks like you are using a familiar library function where in actuality you are using something totally different.

Single character variable names. I can't believe academics encourage this practice still.

I can think of a lot of Python-specific ones, but I'll limit myself to one case.


class SomeObject (object):
    member = OtherObject() #This will hurt you.
