os.popen[2-4] does not work with parameters inside quotes, nor do
os.popen. At least on Windows.

import os
cmd = '"c:\\command.exe" "parameter inside quotes"'
os.popen4(cmd)

Results in the following error message:

'c:\\command.exe" "parameter inside quotes' is not recognized as an
internal or external command,
operable program or batch file.

Not surprising.  Pick command.COM or cmd.exe.

Did you try with having the exe-file in another directory with spaces:
"c:\path with spaces\command.exe"?

What Windows version are you running?

Take a look at this (especially Tim Peters' very thorough explanation in
the Followups section):

http://sf.net/tracker/?func=detail&aid=512433&group_id=5470&atid=105470

Perhaps this is what you are seeing? One workaround (that isn't
beautiful) might be to create a temporary batch file with your command
line and execute that batch file.

This wraps, but here's the result:

Python 2.4a0 (#46, Oct 25 2003, 09:39:59) [MSC v.1200 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.

>>> import os
>>> cmd = '"C:\\Program Files\\Microsoft Visual

Studio\\Common\\Tools\\dfview.ex
e" "parameter inside quotes"'
>>> os.popen4(cmd)

(<open file '"C:\Program Files\Microsoft Visual
Studio\Common\Tools\dfview.exe"
"parameter inside quotes"', mode 'w' at 0x008E4EE0>, <open file '"C:\Program
Fil
es\Microsoft Visual Studio\Common\Tools\dfview.exe" "parameter inside
quotes"',
mode 'r' at 0x008EC660>)
