Python Program to Determine Population and Plot a Graph

import matplotlib.pyplot as plt
e=2.718
def size_of_population(t):
return (15000*(1+t))/(15+e)
t=[0,1,2,3,4,5,6,7,8,9,10]
p=[]
for i in t:
p.append(size_of_population(i)+1000)
plt.plot(t,p)
plt.axis([0, max(t)+2, 0, max(p)+2])
plt.xlabel('Time')
plt.ylabel('Population')
plt.show()
