I agree, pyscripter if using windows used to be my favorite, and is in the
top 3 favorite python editors. Based on your tastes and your editor
selection I'd say that you might like another batteries-included(not much
config, autocomplete, ability to test code/etc... ) editor for python native
to both Windows & Linux would be that of Aptana Studio(primary focus is
that of web), customized from eclipse however depending on the distro you
use is may have to be compiled. But pydev(Aptana's python-based plugin) is
included with Aptana Studio. If indeed the lack of a pre-configured
system-ready package/compiling from source is not enticing, then one can use
the pkg-management conducive to your distro and install eclipse(as most
distros have that). Then go to the plug-in installation in Eclipse's help
menu and install pydev, from I believe http://pydev.org. Its def. A great
editor, and I have used it alot, and the fact both windows, and linux use
it your able to seamlessly resume your work no matter what os your using.
But Wine most certainly isnt bad and I have gotten if memory serves me
correctly pyscripter to work on my archlinux install. Some other editors
that are more so geared towards python development on linux are cream/pida,
eric, & spyder(probably most similar to pyscripter). My one concern with
pyscripter I believe is that its not being updated currently(I could be
wrong, but I think thats what I last saw. ). Good luck!

However I stumbled upon PyScripter and I find it really amazing.
Pity it is only for Windows.
WINE?
Ramit
I?concur. Pyscripter , though?I've?only installed it a few days ago, seems
to be one of the better ones. I am?running?it in a virtualbox winXP on top
of?Linux?Ubuntu, but i love the simply way you can use tkinter from a
server? No muss no fuss. Just install and go. I understand that the way it
had been built, it can't be readily ported to Linux. Mores the pity.

Missing a return statement in the case of an exception.
Can you explain this? Why would I want the return on the exception?
Because if you don't, it will return None.

hello
I need to rewrite area.py program so that it has separate functions for the
perimeter and area of a square, a rectangle, and a circle (3.14 *
radius**2).
I am horrible at math and I cannot even figure out what I need to do for
this
Any help would be appreciated
All I have is the menu which looks like this
?
?
?
?
import math
print "your options are:"
print " "
print "1) Area(SQUARE)"
print "2) Area(RECTANGLE)"
print "3) Area(CIRCLE)"
print "4) Perimeter(SQUARE)"
print "5) Perimeter(RECTANGLE)"
print "6) Perimeter(CIRCLE)"
print "7) Exit"
while True:
??? selection = raw_input("Please select an option from the menu.: ")
python area.py
print "Calculate information about a rectangle"
length = input("Length:")
width = input("Width:")
print "Area",length*width
print "Perimeter",2*length+2*width
print 'To find the area of a rectangle,'
print 'Enter the width and height below.'
print
w = input('Width:? ')
while w <= 0:
??? print 'Must be a positive number'
??? w = input('Width:? ')
h = input('Height: ')
while h <= 0:
??? print 'Must be a positive number'
??? h = input('Height: ')
print 'Width =',w,' Height =',h,' so Area =',area(w,h)

Just what don't you understand? If it's really just the math, then go
ahead and write dummy versions of the needed functions and control
structures, and then ask for help modifying the code.
There are bugs in the present code that have nothing to do with math,
and I'm not just referring to the line "python area.py".

Have you learned about functions? Here's an example. Put this in a file and
try it.
def get_drink():
answer = raw_input("Would you like a cup of tea? (y/n) ").lower()
while answer not in ('y', 'yes', 'n', 'no'):
print "I'm sorry, I don't understand that response."
print "Please enter Yes or No."
answer = raw_input("Would you like a cup of tea? (y/n) ").lower()
if answer in ('y', 'yes'):
return "a nice steaming cup of tea, with a couple of biscuits"
else:
return "a stale cup of bitter coffee"
drink = get_drink()
print "I have", drink
Notice a few things:
First, you define a function with the "def" keyword, and give it a name, in
this case, "get_drink". Names should usually be verbs ("doing words"),
because
functions do things.
Second, the function normally should use the "return" statement to send a
result back to the caller.
Third, you call the function by name, using round brackets (parentheses) to
indicate to Python that you are calling it, and save the result in a
variable
("drink" in the above example).
And finally, you can then use the variable for further processing.
In your case, you want six functions, to get the area of a square, the
perimeter of a rectangle, etc. So for each function, you need to decide on a
descriptive name, such as this:
def get_area_of_square():
# Ask the user for the width of the square.
...
# Calculate the area.
area = width**2
return area
The dots ... need to be filled in by you. Your program already has code that
asks the user for a width, just grab it and put it inside the function.
The formulae you need are:
SQUARES:
area = width*width = width**2
perimeter = width+width+width+width = 4*width
RECTANGLES:
area = width*height
perimeter = width+height+width+height = 2*(width+height)
CIRCLES:
area = pi*radius**2
circumference = 2*pi*radius
To get the value of pi, put this at the top of your program:
from math import pi
Hope this helps.
