import os
import os.path

class FolderFiles:
	def GetFiles(path,fileExt):
		bPath = FolderFiles.CheckIsPath(path)
		fList = []
		if(bPath):
			for root, dirs, files in os.walk(path):
				for f in files:
					if(FolderFiles.CheckFileExt(f,fileExt)):
						fList.append(f)
		elif(FolderFiles.CheckFileExt(path,fileExt)):
			fList.append(path)
		return fList
	
	def CheckFileExt(filename,fileExt):
		if(fileExt[0] != '.'):
			fileExt = '.' + fileExt
			
		fExtLen = len(fileExt)
		
		if(len(filename) > fExtLen and filename[-fExtLen:] == fileExt):
			return True
		else:
			return False
			
	def CheckIsPath(filename):
		if(os.path.isfile(filename)):
			return Flase
		else:
			return True
			
			

Example :

fList = FolderFiles.GetFiles(u'F:/','py')
for f in fList:
	print(f)

os walk is pretty slow use this : 

its about 10-25 times faster

is there a need for new class?

import os
wut = raw_input("Folder directory: ")
whichfiles = raw_input("extension: ")
files = os.listdir(wut)
for name in files:
    if name.endswith('.'+whichfiles): print name

print out >>

C:Python27python.exe C:/Users/asus/PycharmProjects/test-esteron.py
Folder directory: c:/python27
extension: py
adminpage.py
constInfo3.py
dll.py
hash_id.py
insa.py
post.py
stealer.py
uiminimap.py
uitaskbar.py

xd.py
xd2.py

Process finished with exit code 0

or manuel

import os
files = os.listdir("c:/python27")
for name in files:
    if name.endswith('.py'): print name
