Python, Restarting the entire code so that moving objects and everything (not just the loop but the whole code)

I am building a computer simulation of an N Body Problem for my science fair project. I want the simulation/code to playback when it finishes so that it can be constantly viewed by other people that walk by. I am using VPython which has worked fine for making the simulation but I can't figure out a way to make all the objects go back to the initial position when restarting the whole code. My loop is using:

finished = False
while not finished:
    rate(100)

then when certain things happen I use if statements to get the next part of the simulation going, ex: more stars

if time >= 4.5:  #Millions of Years
   F = G*(m1*m2)*r/r**3

does any body know how to make the whole code repeat its self? the best I could come up with is putting all the objects in the loop and then using continue, but I don't fully know how to use continue and break.

Solution

  • EX:

    restPos = (x,y,z)

while True:
    if Star1.pos = resetPos:
        #reset star positions, EX below
        star1.pos = (0,0,0)
    else:
        F = G*m1*m2*r/r**3
        Star1.pos += F*dt #or however i did this, haven't used the code in a bit
