Port of python stdlib to other languages.
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. -- http://mail.python.org/mailman/listinfo/python-list
Re: Port of python stdlib to other languages.
AFAIK not. You could try elmer Elmer looks very interesting, but not really what I was getting at. What do you need C for anyway? Or, to put it the other way round - why not expose whatever you need in C as python extension, and write your app in Python? 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. -- http://mail.python.org/mailman/listinfo/python-list
Re: Noob question: Is all this typecasting normal?
You might better do bet = int(raw_input(Enter your bet)) because then you don't need to later on convert bet again and again. 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. -- http://mail.python.org/mailman/listinfo/python-list

Re: How to restrict lenght of entry widget to certain number of character
Peter Otten wrote: Michael Onfrek wrote: import Tkinter as tk Hi! Can you explain what line above mean? I also found : http://effbot.org/zone/tkinter-entry-validate.htm It works for me, but I not really understand how? :) import Tkinter as tk Make objects defined in Tkinter available under the tk prefix. E. g. to access an Entry you can do 'tk.Entry'. Had you imported it 'import Tkinter' you would have to do 'Tkinter.Entry' instead. So you are saving a few keystrokes. Doing 'from Tkinter import *' saves you still more keystrokes but is considered bad style except for demonstration purposes. var = tk.StringVar() entry = tk.Entry(root, textvariable=var) Create a StringVar and connect it to the Entry widget. Any changes the user makes in the Entry are reflected in the StringVar's value which can be accessed with its get() method. max_len = 5 def on_write(*args): s = var.get() if len(s) max_len: var.set(s[:max_len]) Define a function that doesn't care about the arguments passed to it. It reads the current value of the StringVar 'var' and, if necessary, trims it to 'max_len_' characters. var.trace_variable(w, on_write) Tell the StringVar to call the function on_write() every time its value is changed. So every time the user edits the data in the Entry, in turn the Entry changes the data of the StringVar, which calls the on_write() function which may or may not change the StringVar -- and that change is reflected in what the Entry displays. This smells like an endless loop, but so far we seem to be lucky... If you look again at Fredrik Lundh's ValidatingEntry, you will find all the elements explained above packed nicely into one class, with the extra refinement that he keeps another copy of the value which is used to restore the old state when the new value is found to be invalid.

Looking at your code snippet, I think you have a lot of other errors before. class 1: self.entry = Entry(self.entryframe) NameError : self is not defined etc...

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:
shudder Does Python even allow numeric class names?
:-D don't know
REAL code, stripped to the minimum that duplicates your problem,
is always better than pseudo-code...
I thought that is it...
self.entry = Entry(self.entryframe)
self.entry.pack()
self.button = Button(command = self.callclass2window)
def callclass2window
c = 2()
class 2:
def ins(self)
NO : ???
d.entry.insert(variable)
d = 1()
What, might I ask, does .insert() /do/ for an Entry() object?
That insert text into entry object.
As far as I can tell, class 1 is creating some GUI button.
Pressing that button invokes your callclass2window(), which creates a
new class 2 instance, and then throws it away.
Yes, exactly
Give us code that we can /run/ and we might be able to give you
an answer...
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('Return',(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

d.entry.insert(0, text)# must insert in other window
d = First() #First window
The problem is that First.__init__() never returns so the instance of
First is never bound to d. Take the line
self.root.mainloop()
out of First.__init__() and and the line
d.root.mainloop()
at the end of the program and it will work as you expect.

O, God! It works! Thousend of thanks!
By the way, the second window appears not activ, is there an option to
make it activ on start?
