[Tutor] unable to import Image module from my application
I am using Python Image library on windows and it is running well. I am using RHEL E4 on another machine and when I installed python-imaging-1.1.6-2.el4.rf.i386.rpm, still i am not able to call the Image and ImagOps modules from my application on this Linux machine. After that --I manually added Imaging1.1.4 folder in /usr/lib/Python2.4/site-packages and added entry in easy_install.pth. After that, I am able to import the modules from python prompt, but still I am not able to import from my application. I am not able to figure out the exact reason for this. Kindly guiide me.

Re: [Tutor] Text Scatter Plots?
Wayne Watson [EMAIL PROTECTED] wrote Before GUIs, crude scatter plots and histograms on TTYs and IBM electronic typewriters were used with only the symbols on the keyboard. Some were pretty decent and effective. Basioc charts can be done that way but usually they are just produceed by print statements with no special charting or plotting software. The earliest plotting software that I'm aware of all used bitmap imaging to the dot matrix printers of the time I don't really want to dabble with graphics at this point The point of the graphics libraries like gnuplot is that they make it easier to produce real graphics than it is to try fancy printing techniques. I don't want to get into all the finery of using GUIs. The plotting libraries can usually throw up a window for you. It won't be a full GUI application just a floating window in screen with a graph drawn in it. Check out the screenshots. Alternatively they can save the image to a file which you can display in any graopghics program or web browser of your choice. However, it seems as though there ought to be some really simple set up to just produce a scatter plot. Maybe I'm overestimating the difficulty. One way to find out would be to try writing one yourself. You could then make it available to the community.

I'm not sure that I understand what you are trying to do.
But trying to replace cmd.exe is a very very bad idea.
Lots of bits of your operatinfg system rely on cmd.exe
and bad things are likely to start happening!
how can I get the return value from
os.system()
Same as any other function:
retval = os.system('notepad.exe')
because I was thinking I can do soothing with os.system(), In
case my question is not clear, just like an IDE that plugged in
another
.exe application.
Sorry, that didn't clarify anything for me! :-)
Are you trying to write your own operating system shell
environment (to use instead of cmd.exe)? Are you trying to
write a Python based command shell? Or are you trying
to create your own IDE?
I'm confused.

[Tutor] Question on DOMImplementation Objects
Does the DOMImplementation interface support schemas?
I'm tweaking an example from a book to process a flat file registration
database:
from xml.dom import implementation
class RegistrationParser:
def parseFile(self, fileAsString):
# Create DocType Declaration
doctype = implementation.createDocumentType('registrations', '',
'archive.xsd')
# Create empty DOM Document and get root element
doc = implementation.createDocument('', 'registrations', doctype)
elemDoc = doc.documentElement
. . .
If I leave archive.xsd out of createDocumentType will it just generate
an XML document without validation?
