Gravity doesn't works, and my character just moves right and really fast

[izmamonke]

So I could fix my last error thanks to an user, but when I run the game my character just sticks in the air and only can move left when I press rioght and when I press right just moves a little, but when I press it again just moves so quickly to the right that leaves the screen.
The lines that I wrote so you guys can locate them easly: (49-70) collision movement, (111) code so the def move works

Forget about collisions and see if you can get moving around to work. The subject mentions gravity, but there is not a gravity calculation anywhere in your code.
