Here is my code, all I need help with is getting the text to display in a graphics window.

I have tried several different ways and I'm not getting any errors either. I bolded the part that I'm having trouble with.

The other ways I have tried have been pounded out.

#Noliving, Lab 09, problem 7 on page 160

#I have not shared this program with anyone and can one walkthrough this program

#These two are importing the graphics and the math libraries.

```
from graphics22 import *
import math
#This is the def userinput function(The name is made up just like the following functions up to def main():), it is asking for the radius and the yint values from the user and then returns them
#The return is returning t
def userinput(radius, yint):#This is using the radius and yint values for this function
radius = input ("Enter the radius of the circle, has to be 10 or less of the circle.: ")
yint = input("Enter the yint of the circle, less than or equal to 10: ")
return radius, yint ##This is returning a value(S) to the caller. It is exiting the function and returns control to the point where function was called.
#This is the def windowcheckuserinput funciton of radius and yint inputs, it is using if statements to check to the radius and yint values
#As you can see if radius is above the value of 10 then you get a print statement saying your radius is to big and so on and so on for the radius and yint.
#The abs stands for absolute value, as long as the radius and yint values are within absolute value of 10 we return to radius yint. not then return 0, 0.
def windowcheckuserinput(radius, yint):#This is using the values of radius and yint throughout this function
if radius > 10:
print "Your radius is to big"
if radius < -10:
print "Your radius is to small"
if yint > 10:
print "Your yint value is to big"
if yint < -10:
print "Your yint value is to small"
if abs(radius) <= 10 and abs(yint) <= 10:
return radius, yint ##This is returning a value to the caller. It is exiting the function and returns control to the point where function was called.
else:
return 0,0 ##This is returning a value to the caller. It is exiting the function and returns control to the point where function was called.
#This is the def creatingwindow function. It is creating a window at 800x600 size window. It has a coordinate system that ranges from -10 to 10.
#Which means that the user input value has to be a whole number between those values in order for it show up on the window.
#Of course if you use mousepoints the mouse clicks have to be within the window to be counted and to be displayed.
def creatingwindow():
win = GraphWin("The revised intercept program", 800, 600)
win.setCoords(-10, -10, 10, 10)
return win #This is returning a value to the caller. It is exiting the function and returns control to the point where function was called.
#This is the def window2 function. It is creating circle at the center point of the window that has been created.
#The radius input is used for the size of the circle the larger the radius, which is also radius2, the larger the circle is.
#line is the line that shows up on the window. The line is based off of the yint user input which is made to equal the yint2.
#Because of the points for line are -10 to 10 it means that the line is going to cross all the way across the window.
#The user input for yint2 is used for where in terms of the yaxis where the line is drawn.
#The r2 is the radius2 value being squared so what ever you entered square it. same for y2=yint2
#Some is taking the those two values subtracting them and then times it by .5 so what ever the value is divide it by half basically and then printing it.
#Some is meant to be a check and go part to make sure I had the program working.
#X value is going to be what is used to create the red circle at the points where the yintercepts the circle at on the xaxis.

print x
return circ, line, x #This is returning a value(s) to the caller. It is exiting the function and returns control to the point where function was called.
#This is the def redcircles function. We are creating two circles that are filled with the color red. The .3 stands for its size. increase that value
#and you increase the size of the red circles.
#The x2 is the value that the line or yint2 is intercepting the circle on the x axis it uses this value to place the circles on the x axis on the circle.

label = Text(Point(-1,-8), "Positive Intersection")

#radius and yint and yint2 and radius2 = 0. The radius and yint are given there values then by the userinput.
#Radius2 and yint2 equal the values of radius and yint from the windowcheckuserinput function.
def main():
print "This is going to be drawing a circle and you will be giving"
print "The radius of the circle. Then it will find the y-int. This has to be between the (not including) positive and negative values of the radius and must be less or equal to 10"

Thanks again for the help in advance.
