The current project is for Linux.
i would like delete the extention *.pyc and files name sommefilestmp.flv and files on folder log

why multiple files with one line, why not write a function which does this (and which you optionally call recursively for sub dirs)?
Are you processing a single directory or a tree (dir and sub-dirs)?

This solution is only available to members.

You can feed the output of glob() or iglob() into os.remove()
Example:
Example:
os.remove(glob.glob('c:\users\aikimark\downloads\Python\*.pyc'))
@aikimark:
my python version does not allow to pass a list to os.remove(), and glob.glob() returns a list. perhaps python 3 allows this?
if you really wanted to write a oneliner you could do:

ty it works :)
that is why I included iglob(), since it returns an iterable

iglob doesn't work either:
python 3.2.3 doesn't seem to handle this either.
Perhaps this is a feature just working with very

well, dang. :-(
Did you try a comprehension syntax?
[os.remove(x) for x in glob.glob("*.xxx")]
@aikimark
your most recent suggestion works of course as you pass just one value per call to os.remove()
On the other hand it's not shorter than my previously suggested
Your and my one-linerare a little weird because the create an intermediate list of None values just to have it destroyed afterwards.
Both are only one line shorter than the explicit for loop of my initial answer.
I'm not sure it's really worth a list comprehension or a map() call

for filename in filenames:

I agree with your analysis. I only posted my post-closure comments to help future readers and to confirm that my earlier comment wasn't too 'crazy'. I'm still learning Python, so it still takes me a bit longer than it should to arrive at an answer. Thanks for your participation.
