RuntimeWarning: invalid value encountered in divide

Question

I have to make a program using Euler\'s method for the \"ball in a spring\" model

from pylab import*
from math import*
m=0.1
Lo=1
tt=30
k=200
t=20
g=9.81
dt=0.01         


        

Answer 1

I think your code is trying to "divide by zero" or "divide by NaN". If you are aware of that and don't want it to bother you, then you can try:

import numpy as np
np.seterr(divide='ignore', invalid='ignore')
