Pythonic way to remove directories from a file listing

I can think of easy ways to accomplish this, but what is the most pythonic way? I get a开发者_开发技巧 file listing for os.listdir, and some may be directories.

I could check through each one in a loop and check if os.isdir returns false, then remove it from the list. What is a pythonic way to write this?

---

[x for x in os.listdir(...) if not os.path.isdir(os.path.join(..., x))]

---

files = filter(lambda f: os.path.isfile(os.path.join(path, f)), os.listdir(path))

OR

files = [f for f in os.listdir(path) if not os.path.isdir(os.path.join(path, f))]

Edited: removed bug per Ignacio's answer (added in calls to os.path.join)
