'numpy.float64' object has no attribute 'plot'

Question

I have a very simple code but at the end i found problem which I couldn't solve or find any solution. I can't draw plot. All I get is error AttributeError: 'numpy.float64' object has no attribute 'plot'

import pylab as p
import numpy as np
import sympy as s
import matplotlib
from random import random

X=np.arange(0,1000)
y=np.random.randint(100,size=1000)

if len(X)==len(y):
    print "ok"
else:
    print "not ok"

 polyfit=np.polyfit(X,y,6)
 poly1d=np.poly1d(polyfit)
 print poly1d


i=1
my=[]
for i in X:
    p=poly1d(i)
    my.append(p)

 print my

 p.plot(X,my)
 p.show()

I look after docs but I found nothing,google also can't help me.

Solution

You've overwritten the pylab module accidentally later on in your code by assigning something else to p. You can avoid this by just importing pylab and using, for example, pylab.plot.

You've also got some indentation issues, remember that indentation matters in Python.

Using matplotlib.pyplot is generally recommended as opposed to using pylab. As such I've modified the code below to use pyplot over pylab. I've also removed some unneeded parts of the code and generally tidied it up.

import matplotlib.pyplot as plt
import numpy as np
from random import random

X=np.arange(0,1000)
y=np.random.randint(100,size=1000)

if len(X)==len(y):
    print("ok")
else:
    print("not ok")

polyfit=np.polyfit(X,y,6)
poly1d=np.poly1d(polyfit)

my=[]
for i in X:
    p=poly1d(i)
    my.append(p)

plt.plot(X,my)
plt.show()
