List files ONLY in the current directory

You can use os.listdir for this purpose. If you only want files and not directories, you can filter the results using os.path.isfile.

example:

files = os.listdir(os.curdir)  #files and directories

or

files = filter(os.path.isfile, os.listdir( os.curdir ) )  # files only
files = [ f for f in os.listdir( os.curdir ) if os.path.isfile(f) ] #list comprehension version.

Just use os.listdir and os.path.isfile instead of os.walk.

Example:

import os
files = [f for f in os.listdir('.') if os.path.isfile(f)]
for f in files:
    # do something

---

But be careful while applying this to other directory, like

files = [f for f in os.listdir(somedir) if os.path.isfile(f)]

which would not work because f is not a full path but relative to the current directory.

Therefore, for filtering on another directory, do os.path.isfile(os.path.join(somedir, f))
