Printing the name of a variable
Does an arbitrary variable carry an attribute describing the text in its name? I'm looking for something along the lines of: x = 10 print x.name >>> 'x' Perhaps the x.__getattribute__ method? Thanks. -- http://mail.python.org/mailman/listinfo/python-list

Open file in default app and exit in Windows
I am using the following to open a file in its default application in Windows 7:
from subprocess import call
filename = 'my file.csv'
call('"%s"' % filename, shell=True)
This still leaves a python process hanging around until the launched app is
closed. Any idea how to get around?

Stripping characters from windows clipboard with win32clipboard from excel
I have an excel file. When I select cells, copy from excel, and then use win32clipboard to get the contents of the clipboard, I have a 131071 character string. When I save the file as a text file, and use the python 3.3 open command to read its contents, I only have 80684 characters. Excel (and other programs too) appends a bunch of b'\x00' (or similar) characters. Is there a pythonic way to strip these out? -- https://mail.python.org/mailman/listinfo/python-list
Re: Stripping characters from windows clipboard with win32clipboard from excel
Hi Steven. Here is my code: import win32clipboard, win32con def getclipboard(): win32clipboard.OpenClipboard() s = win32clipboard.GetClipboardData(win32con.CF_TEXT) win32clipboard.CloseClipboard() return s I use this helper function to grab the text on the clipboard and do useful things with it. Sorry about the description; I have stuff to learn about strings and python 3.3. To get the string length, I just do len(s). There were 10 columns and 700+ rows of data, so len(s) returned 80684 from an excel spreadsheet saved as a text file. >From the clipboard contents copied from the spreadsheet, the characters >s[:80684] were the visible cell contents, and s[80684:] all started with >"b'\x0" and lack any useful info for what I'm trying to accomplish. -- https://mail.python.org/mailman/listinfo/python-list

Aha, I need to use str(s, encoding='utf8').rstrip('\0').

Odd behavior from excel. It seems as though the clipboard contents will vary according to the clipboard size. For example, in my 13 column row I select 2023 rows, copy to the clipboard, and def getclipboard(): win32clipboard.OpenClipboard() s = win32clipboard.GetClipboardData(win32con.CF_TEXT) win32clipboard.CloseClipboard() return s s = getclipboard() len(s) gives me 16298. If I select one additional row, len(s) balloons to 32767. In the first case, s[-10:] is b'0.032573\r\n'. In the second case, s[-10:] is b'\x008\x008\x000\x005\x00\t' Does anyone know what is going on with that? -- https://mail.python.org/mailman/listinfo/python-list

Thanks to everyone for their help. Using everyone's suggestions, this seems to
work:

win32clipboard.OpenClipboard()
s = win32clipboard.GetClipboardData(win32con.CF_UNICODETEXT)
win32clipboard.CloseClipboard()

s = s[:s.index('\0')]
