[Solved] Code not working (python) [closed]

by 


if d<r:
    vx,vy,ax,ay=0,0,0,0
    return [vx,ax,vy,ay]

This isn’t a function so you can’t use return. If you want to add those values to a list you can make a new list:

new_list = [vx,ax,vy,ay]

You don’t need to use return outside of a function because those variables are already in scope. When you use variables inside a function they aren’t in the same scope as the rest of your program. For example:

>>> def foo():
        a =10
>>> a = 1
>>> foo()
>>> a
1

The a inside the function doesn’t effect the a outside of. In you if statement you don’t need a return because it is in the same scope. The assignment of the variables doesn’t need to be returned from anywhere because it’s the same scope.

And as @Hugh Bothwell pointed out you have a typo in your function call should be:

scipy.integrate.odeint()
