ftplib and the retrbinary() command

[-=disAbled=-]

I'm trying to finish up my first Python program. The program was built to help me maintain and add content to my webpage (it's nothing fancy...just pure html). Everything was smooth sailing (hey, python kicks some serious butt), until I ran into problems using retrbinary() to download files. The problem lies in the FTPDown() function of my program. When I try to execute the funcition i get a fun error message:

Username and Password successfully verified
220 FTP Server ready

Downloading last.htm
Traceback (most recent call last):
  File "HTMLFixer.py", line 303, in ?
    MainMenu()
  File "HTMLFixer.py", line 212, in MainMenu
    FTPDown()
  File "HTMLFixer.py", line 46, in FTPDown
    myftp.storlines('RETR '+filename,fileOut.write)
  File "C:\Documents and Settings\tbeck\My Documents\tools\pt\lib\ftplib.py", line 428, in storlines
    buf = fp.readline()
AttributeError: 'builtin_function_or_method' object has no attribute 'readline'

I've been hunting around, and everything seems to indicate that there should be nothing wrong with my code. Obviously, though, something is.

I'm running Python 2.4.1 on Win2k.

Could someone explain what I'm doing wrong here? Oh, and also, i'd like to know the os command for clear screen in windows. Seems like 'cls' should work somewhere, but....

code follows:

from ftplib import FTP
import os
import re
import sys
import fnmatch

def FTPDown():
	print
	print
	ftplocation=raw_input("Please Enter the FTP location:  ")
	print "Connecting to "+ftplocation
	try:
		myftp=FTP(ftplocation)
	except:
		print "Could not connect to "+ftplocation
		raw_input("--Press any key to return to main menu--")
		ClearScreen()
		return
	print
	print "Connected to "+ftplocation
	myftp.set_debuglevel(0)
	username=raw_input("Please Enter Username:  ")
	password=raw_input("Please Enter Password:  ")
	print
	print
	try:
		myftp.login(username,password)
	except:
		print "Login Failed: Username or Password is incorrect"
		myftp.close()
		raw_input("--Press any key to return to main menu--")
		ClearScreen()
		return
	ClearScreen()
	print "Username and Password successfully verified"
	print myftp.getwelcome()
	print
	fileList = myftp.nlst() 
	targetList= [fileName for fileName in fileList if fnmatch.fnmatch(fileName,'*.htm')]
	for filename in targetList:
		print "Downloading "+filename
		try:
			fileOut=open(filename,'wb')
		except:

Maybe in the future, I should look closer at the line where I'm having a problem. It's really hard to get the retrbinary() command to work when you have storlines() where it should be. :o
