Gravity for side scrolling game - Mario like clone

Question

I'm trying to code for gravity in python with pygame to create a Mario clone...I think the values for x has to be placed in a quadratic formula to solve for y that changes with the speed of movement, so when stationary, x won't change. I'll have to have some sort of loop because if x is 0, y can't change, right? I'm so list right now. If there's an easier way to do this, let me knos.

Here is a nice tutorial in processing about applying an ascending force to an object.

You can apply the same concepts to your python script.
