I was looking around in my Python folder and saw something to do with
that IDLE thing you were talking about. When I right clicked on a .py
file, it said edit with IDLE. I opened it and it was my code but each
line was a different color. It looked confusing so I decide to save
it for later. I knew that I could get the run thing to do the command
thing, but I had forgotten how to get the black window to come up.
Ok. Well, I tried to us the cmd window. It says python: can't open
file 'area.py' I'm guessing that's not good. It won't open any of
my .py files. It's because of where I saved them. I can see how this
i going to work now. Ok so I'll just move them to the place that the
command line says. Now it still won't run my other program:
# Area calculation program
print "Welcome to the Area calculation program"
print "-------------"
print
# Print out the menu:
print "Please select a shape:"
print "1 Rectangle"
print "2 Circle"
# Get the user's choice:
shape = input("> ")
# Calculate the area:
if shape == 1:
height = input("Please enter the height: ")
width = input("Please enter the width: ")
area = height*width
print "The area is", area
else:
radius = input("Please enter the radius: ")
area = 3.14*(radius**2)
print "The area is", area
Perhaps it isn't written correctly. I don't think it likes the pound
signs. I'm not sure. But, I did go to that mailing list you
recommended. Thanks for that.
