Sorry for ignoring the thread.

If it is not quoted by default, you can quote it explicit. If this be the case where the filename is obtained from the OS. 

newname = '"' + filename + '"'

If you are passing the filename, then just pass it as "filename".

Yes, '&' character is being interpreted by the SHELL command interpreter and python is not receiving it. Thats why it is failing. You need to escape the special character or quote the entire arg.

How are you getting the params? 
1) Like I said, if you are passing it, escape the special characters or quote the entire thing.
2) If you getting it from a python function like os.listdir(), I assume it should be readily usable.

[ors at goofy ~]$ cat 1.py
import sys
arg = None
if len(sys.argv) > 1:
    args = sys.argv[1:]

print args
[ors at goofy ~]$ python 1.py something anotherthing \& yetanother
['something', 'anotherthing', '&', 'yetanother']
[ors at goofy ~]$ python 1.py "something anotherthing & yetanother"
['something anotherthing & yetanother']
[ors at goofy ~]$





If filenames are obtained as os.listdir(), then quote each other
