You've got already an "x" placed in your variable stars that's why.

Hi,
Here is my script :
It propose to replace some words in a file with a regular expression.
It create a copy to write on it, and if there isn't an error, it delete the
original by the copy with "os.rename" at the end.
My problem is, if I work on a huge file, I'll try to avoid to read the file

Hi,
On relfection, it's clear that:
1. the "(-a -b VALUE-B | -c -d VALUE-D)" syntax is not
implemented by the argparse module;
2. and get this syntax with "argparse + hacking" is not very clean.
So, finally I'll use the docopt module version 0.6.1.
For the inheritance of common options, I'll us

Yes, but this is not the same syntax. I want this syntax :
my-script (-a -b VALUE-B | -c -d VALUE-D)
I don't want this syntax:
Hello,
Up. ;-)

I discovered Python a few months ago and soon decided to invest time in
learning it well. While surfing the net for Python, I also saw the hype
over Ruby and tried to find out more about it, before I definitely
embarked on studying and practicing Python. I recently found two
sufficient answers for

We use the latter one in the past. As long as
your output is plain enough. It's effective
and MS-free.
The former should be more powerful. Not tested
here.
Hope this helps
