I have written very simple Python code to solve the simple harmonic oscillator using Euler method, but I am not sure if the program is correct or not. I would be very grateful if anyone can look at my code and suggest further improvements since I am very new to this programming thing.

I have a chunk of code that's working properly but it's way too complicated to read:
addCollision (bodyA, bodyB) {
var bodyC, i3;
if (bodyA.collision === null && bodyB.collision === null) {
bodyA.collision = this.collisions.length;
bodyB.collision = bodyA.collision;
...
Is there any better way to define the function at the class which shares most of the same parameter like functools.partial.
