>>> import os, fnmatch
>>> filter(lambda x: fnmatch.fnmatch(x, '*.cc'), os.listdir('.'))
['Clientmenu.cc', 'Configmenu.cc', 'Iconmenu.cc', 'Rootmenu.cc', 'Screen.cc', 
'Slit.cc', 'Toolbar.cc', 'Window.cc', 'Windowmenu.cc', 'Workspace.cc', 
'Workspacemenu.cc', 'blackbox.cc', 'main.cc']

for those using python 2.x that can also be written as:

>>> [n for n in os.listdir('.') if fnmatch.fnmatch(n, '*.cc')]
