Question

I am new to python and one of the problems I am working on is to plot 500 pairs of successive random numbers. I have a formula that generates the numbers seen below:

x-axis

>>> a=128
>>> c=0
>>> m=509
>>> n=500
>>> seed = 10
>>> for i in range (1,n):
    new_seed=(a*seed+c)%m
    seed = new_seed
    print new_seed

y-axis

>>> a=269
>>> c=0
>>> m=2048
>>> n=500
>>> seed = 10
>>> for i in range (1,n):
    new_seed=(a*seed+c)%m
    seed = new_seed
    print new_seed

What I am wondering now is how I can turn these results into an array or list. I have attempted to put plt.plot(new_seed) in the loop statement but that did not work when I tried to plot. Any ideas?

I used import matplotlib.pyplot as plt

Thanks in advance for the help!!

You should probably do some (more)python tutorials.. lists are a fundamental aspect of python and it seems you dont understand them…

import matplotlib.pyplot as plt
import random
x = []
a,seed,c,m,n = 128,10,0,509,500
for i in range (1,n):
   new_seed=(a*seed+c)%m
   seed = new_seed
   x.append( new_seed)


a,seed,c,m,n = 269,10,0,2048,500
y= []
for i in range (1,n):
   new_seed=(a*seed+c)%m
   seed = new_seed
   y.append( new_seed)
plt.plot(x,y)
plt.show()
