These libraries drive me totally nuts. Sorry, just had to get it out there.
Anyway, I open the cmd window, and typed this: 'easy_install python graphics'. So, it starts up and runs/downloads the appropriate library from the web. I get confirmation (in the cmd window) that it finishes, then I try to run this script.
# futval_graph2.py
from graphics import *
def main():
# Introduction
print "This program plots the growth of a 10-year investment."
# Get principal and interest rate
principal = input("Enter the initial principal: ")
apr = input("Enter the annualized interest rate: ")
# Create a graphics window with labels on left edge
win = GraphWin("Investment Growth Chart", 640, 480)
win.setBackground("white")
win.setCoords(-1.75,-200, 11.5, 10400)
Text(Point(-1, 0), '0.0K').draw(win)
Text(Point(-1, 2500), '2.5K').draw(win)
Text(Point(-1, 5000), '5.0K').draw(win)
Text(Point(-1, 7500), '7.5k').draw(win)
Text(Point(-1, 10000), '10.0K').draw(win)
# Draw bar for initial principal
bar = Rectangle(Point(0, 0), Point(1, principal))
bar.setFill("green")
bar.setWidth(2)
bar.draw(win)
# Draw a bar for each subsequent year
for year in range(1, 11):
principal = principal * (1 + apr)
bar = Rectangle(Point(year, 0), Point(year+1, principal))
bar.setFill("green")
bar.setWidth(2)
bar.draw(win)
raw_input("Press <Enter> to quit.")
After I hit F5, I get this:
Traceback (most recent call last):
File "C:\Users\Ryan\Desktop\Graphics_Test.py", line 2, in <module>
from graphics import *
ImportError: No module named graphics
