double quote escaping in os.system on windows

Question

I want to escape \'\"\' and all other wild chars in program name and arguments, so I try to double quote them. and I can do this in cmd.exe

C:\\bay\\test\\go         


        

Answer 1

Enclose the arguments in brackets, it works.

CMD /k ("c:\batch files\test.cmd" "Parameter 1 with space" "Parameter2 with space")

Answer 2

Try with os.system('python "test.py" "a" "b" "c"')

You can also use subprocess module for that kind of purpose,

please take a look this thread

UPDATE:When I do, os.system('"test.py" "a" "b" "c"'), I got similar errors, but not on os.system('test.py "a" "b" "c"'), So, I like to assume that first parameter should not be double-quoted

Answer 3

Furthing google comes this page

To launch a batch script which itself requires "quotes" 
CMD /k ""c:\batch files\test.cmd" "Parameter 1 with space" "Parameter2 with space"" 

cmd = '""test.py" "a" "b" "c""' does work!

Answer 4

Actually, it just work as design. You can NOT use os.system like that. See this: http://mail.python.org/pipermail/python-bugs-list/2000-July/000946.html
