RE: python cgi script not understood as html

[Iyer, Prasad C]

Your python script is not getting executed.
I guess there is something wrong with the server configuration.

Small utility program for the windows

[Iyer, Prasad C]

Hi,
I am trying to create a small utility program which would be configured
in registry. Something like this
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\*\shell\ShortCut\command]
@="\"python C:\\workspace\\python\\Tut\\ShortCut.py\""


It gives me access denied exception when I try it.
Can anyone help me out.
Following is the code

from Tkinter import *
import sys

class BaseClass(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.grid()
self.createWidget()
def createWidget(self):
self.text=Text(self, width=20, height=3)
self.text.grid(row=0,column=0)
Button(self, text="ok", command=self.addText).grid(row=1,
column=0)
def addText(self):
print "hello world"

baseClass=BaseClass()
print sys.argv[0]
for i in range(0, len(sys.argv)):
print sys.argv[i]
baseClass.mainloop()



I have to modify the code further so that it takes argument.

Abstract Methods & Abstract Class

[Iyer, Prasad C]

Do we have something like abstract methods & Abstract class.

So that my class would just define the method. And the implementation
would be defined by somebody else.

RE: Don't want to serialize a variable of object

[Iyer, Prasad C]

Thanks a lot.

Actually you are right I would be trying same thing now.
Writing my own custom serializable for the object.

But everyone else who face the same problem would come up with their own
Serializable code.

Can't we plug something into cpickle So that it discards some variable from 
being serializable. Similar to __data for private variables. But on second 
thought that would be too much of change that I am asking.

Anyway thanks a lot.

Don't want to serialize a variable of object

[Iyer, Prasad C]

Hi,
I got a class which I need to serialize, except for couple of variable.
i.e.

import cPickle as p
class Color:
def __init__(self):
print "hello world"
self.x=10
self.somechar="this are the characters"
color=Color()
f=file('poem.txt', 'w')
p.dump(color, f)
f.close()

How do I serialize the object color without serializing the x and
somechar variables?
Is there any modifier which prevents the variable from being serialized.




Another question:
Is there a concept of private variables?

#You can't do that. The "from module import *" mechanism explicitly

#
#   from import2 import *
#   from import2 import *
#
#It would be much better, though, to write:
#
#   import import1
#   import import2
#
#Then you can refer to import1.BaseClass and import2.baseClass without

form

Confused with module and .py files

[Iyer, Prasad C]

Actually I am bit confused between the modules and .py file
How do I differentiate between the 2.

For example
I have a file import1.py, import2.py file
Which has few functions and classes
And if I have a class with same name "BaseClass" in both the file

How would I use it if I declare it as given below in my 3rd class

from import1.py import *
from import2.py import *

RE: Python CGI Script

[Iyer, Prasad C]

I guess your python script isn't getting executed.

a. I guess you might have to tweak the server if the script is not
getting executed.
b. Maybe your script is getting executed but you are not setting the
"Content-type" parameter which is essential for browser that it is an
html page.

Note :- Set "Content-type" to "text/html" I guess this should work

Subject: Python CGI Script

 Hello,

 I'm a data-structures course TA trying to write a python CGI script

for automatically compiling and testing students' projects.
Unfortunately, I've run into some questions while writing this, which I
couldn't solve with the various (and helpful) python-CGI documentation.
(It's possible that I'm posting to the wrong group; if so, I'd
appreciate suggestions for the appropriate group.)


1. In my HTML page, I have the following:





 In the above, submission_processor.py is the python CGI script. I
didn't write a URL in the action field, since I'm first testing
everyting on a local machine (running FC4). The first line of
submission_processor.py is

#!/usr/bin/python

and I've done

chmod +x submission_processor.py

 When I hit the "submit" button, my browser (Firefox on FC4) doesn't

run the script; it asks me whether it should open
submission_processor.py or save it to disk. I couldn't figure out why.

2. My HTML page has the option for an instructor to list the various
submissions and scores. Obviously, this should be inaccessible to
students. The instructor has a password for doing this, therefore.
Suppose I place the password inside a python script, and give this
script only +x permission for others. Is this  adequate as far as
security?


 Thanks in advance for answering these questions.


  Efrat

I may be reading this question different than Fredrik.

This example is with old-style classes.

class baseclass:
def __init__(self, arg):
#
# Do some initialization
#

def method1(self, arg):
#
# baseclass method goes here
#

class myclass(baseclass):
def __init__(self, arg):
#
# This method gets called when I instantiate this class.
# If I want to call the baseclass.__init__ method I must
# do it myself.
#
baseclass.__init__(arg)

def method1(self, arg):
#
# This method would replace method1 in the baseclass
# in this instance of the class.
#

myObj=myclass(arg)

I could be way off base, but maybe it will help.
