I'm not looking to write a Python app atm.

Just curious if someone had started a project like this, to, say, make
Python users more comfortable using other languages (for whatever
reason),
or allow other people to try "python-like" code in their language to
see
if it suits them.

Port of python stdlib to other languages.

[vk]

Have there been ports of the Python standard library to other
languages?

I would imagine using pickle, urllib, and sys in C (with pythonic
naming conventions) would be easier than using other libraries to do
the same thing.

Re: Ideas to optimize this getitem/eval call?

What do you mean by 'fail'?
you have;

:: self.codes = {}

so

:: try:
::return eval(self.codes[expr], self.globals, self.locals)

will always return an exception the first time (if this is what you're
referring to).

It's possible that I am, but where's the fun without the risk?
Good thinking in your post though!

I will add "get_date" at some point, and I've modified "get_numeric"
already.
All-right, the moment you've all been waiting for:

-
http://docs.google.com/View?docid=dgsp7w2t_2gwf447g8
-

Provides:
1) user_io.user_io
-- get_text(msg)
-- filter_get(msg, valid_chars)
-- get_numeric(msg)
-- bully_numeric(msg)

2) user_io.progress_bar
-- ping()
-- stop()

Read the doc-strings for details.

I know it isn't perfect, so just yell at me on this thread if you
don't like something and I'll try to fix it.
Actually, I'd rather you fix it yourself and THEN yell at me to update
the module.

have fun!

This is all fine until you give it to an end-user.
This is what I picture:

$ ./script.py
Enter your bet: $10

.. or perhaps "ten", "all", or a jillion other tainted inputs.

Python will try to cast these strings, but will slap you with a
ValueError instead (an error of some sort, at least).


There needs to be a "user_io" or "sanitize" module in the standard
library to take care of this stuff.
Like:

import userio

logic = userio.userio()

number = logic.getNumeric("blah: ") # will offer the user a "re-do" in
case of bad input
number = logic.forceGetNumeric("Enter your bet!: ") # even if input is
tainted, will return some number

text = logic.getText("blargh: ") # return all text

text = logic.setValidText("[A-Za-z]")
text = logic.forceGetText("blargh: ") # return some text, strips
invalid chars


... but there isn't, as far as I know.

 See:

JScript site is now only and exclusively for Internet Explorer 5.5 and

Any other visitors are out of support and interest of Microsoft - at

I've already implemented this with code under my message, but "cut"
copies entrytext, without deleting selection. Any ideas

def copy(self):

Sorry, but I don't get it. There is no deference between my code and

Getting value of radiobutton trouble

[VK]

Hi!
What I'm missing in following code? Cannot get the values of 
radiobuttons. Starting only one class (GetVariant), it works. When I put 
two classes together, it doesn't.
Regards, VK

from Tkinter import *
class GetVariant:
 def __init__(self):
 self.root = Tk()
 self.mainframe = Frame(self.root,bg="yellow")
 self.mainframe.pack(fill=BOTH,expand=1)

 self.firstframe = Frame(self.mainframe,bg="red")
 self.firstframe.pack(side=BOTTOM,expand=1)

 global v
 v = StringVar()
 self.radiobutton = Radiobutton(self.firstframe,text= "Variant 
1", variable=v, value="Variant 1")
 self.radiobutton.pack(side=TOP,anchor=W)
 self.radiobutton.select()
 self.radiobutton = Radiobutton(self.firstframe,text= "Variant 
2", variable=v, value="Variant 2")
 self.radiobutton.pack(side=TOP,anchor=W)
 self.radiobutton = Radiobutton(self.firstframe,text= "Variant 
3", variable=v, value="Variant 3")
 self.radiobutton.pack(side=TOP,anchor=W)



 self.secondframe = Frame(self.mainframe,bg="blue")
 self.secondframe.pack()
 self.var = Button(self.secondframe,text="What 
Variant",command=self.call)
 self.var.pack(expand=1,side=BOTTOM)



 def call(self):
 self.variant = v.get()
 print 'Input => "%s"' % self.variant

class OneButton:
 def __init__(self):
 self.root = Tk()
 Button(self.root,text="click me",command=self.getvar).pack()
 def getvar(self):
 a=GetVariant()

d = OneButton()
d.root.mainloop()

That insert text into entry object.

Yes, exactly

I try:

from Tkinter import *

class First:
 def __init__(self):
 self.root = Tk()  # create window contents as children to 
root..
 self.entryframe = Frame(self.root)
 self.entryframe.pack(fill=BOTH,expand=1)

 self.entry = Entry(self.entryframe)
 self.entry.pack(side=TOP,expand=1,fill=BOTH)
 self.entry.focus()
 self.entry.bind('',(lambda event: self.fetch())) # 
on enter key

 self.button = 
Button(self.entryframe,text="Call",command=self.getvar)
 self.button.pack(side=LEFT,expand=YES,fill=BOTH)

 self.root.mainloop()

 def fetch(self):
 print 'Input => "%s"' % self.entry.get() # get text form entry

 def getvar(self,event=0):
 c=Second(self,self.root)



class Second:
 def __init__(self,parent,s="thing"):
 self.root = Tk()
 self.ent = Entry(self.root)
 self.ent.pack()
 self.btn = Button(self.root,text='Fetch',command=self.fetch)
 self.btn.pack(side=RIGHT)
 def fetch(self):
 text = self.ent.get() # get text form entry in this window
 d.entry.insert(0, text)# must insert in other window

d = First() #First window

What is d = 1() in my example then? And how do I solve this problem?

Access from one class to methode of other class

[VK]

Hi, all!

In my programm i have to insert a variable from class 2 to class 1 and I 
get error NameError: global name 'd' is not defined. How do I get access 
to d.entry.insert() method of class 1

class 1:
self.entry = Entry(self.entryframe)
self.entry.pack()

self.button = Button(command = self.callclass2window)

def callclass2window
c = 2()


class 2:
def ins(self)
d.entry.insert(variable)


d = 1()
