ImportError : No module named graphics

I tried working on a graphics algorthims which requires a graphics package so i imported graphics the code is here

from graphics import *
import time

def BresenhamLine(x1,y1,x2,y2):
""" Bresenham Line Drawing Algorithm For All Kind Of Slopes Of Line """

dx = abs(x2 - x1)
dy = abs(y2 - y1)
slope = dy/float(dx)

x, y = x1, y1

# creating the window
win = GraphWin('Brasenham Line', 600, 480)

# checking the slope if slope > 1
# then interchange the role of x and y
if slope > 1:
dx, dy = dy, dx
x, y = y, x
x1, y1 = y1, x1
x2, y2 = y2, x2

# initialization of the inital disision parameter
p = 2 * dy - dx

PutPixle(win, x, y)

for k in range(2, dx):
if p > 0:
y = y + 1 if y < y2 else y - 1
p = p + 2*(dy - dx)
else:
p = p + 2*dy

x = x + 1 if x < x2 else x - 1

# delay for 0.01 secs
time.sleep(0.01)
PutPixle(win, x, y)

def PutPixle(win, x, y):
""" Plot A Pixle In The Windows At Point (x, y) """
pt = Point(x,y)
pt.draw(win)

def main():
x1 = int(input("Enter Start X: "))
y1 = int(input("Enter Start Y: "))
x2 = int(input("Enter End X: "))
y2 = int(input("Enter End Y: "))

BresenhamLine(x1, y1, x2, y2)

if __name__ == "__main__":
main()


But when i executed this code which gave me this error

python app.py
Traceback (most recent call last):
File "app.py", line 1, in <module>
from graphics import *
ImportError: No module named graphics


So i tried to install graphics package from pip but i too failed.

sudo pip install graphics
Downloading/unpacking graphics
Could not find any downloads that satisfy the requirement graphics
Cleaning up...
No distributions at all found for graphics
Storing debug log for failure in /home/ubuntu/.pip/pip.log


How to rectify this error?

Answer

You have to download this file and put it in the same folder with your script.

From the docstring:

INSTALLATION: Put this file somewhere where Python can see it.
