Python implements the blacklist of downloaded file records,

Python implements the blacklist of downloaded file records,

The Code is as follows:

#! /Usr/bin/python #-*-coding: GBK-*-#-*-coding: UTF-8-*-from ftplib import FTPimport osimport datetimeftp_server = '100. 0.0.1 '# username = 'ponshine' # username password = '1qaz2wsx' # password ftp_path ='/GBCC/'# ftp directory local_path = "C: \ F \ python \ pythonwangtest \ wyjj2 \ "# local directory # connect to FTPdef ftpconnect (): ftp = FTP () ftp. set_debuglevel (2) # enable debug level 2 and display the ftp details. connect (ftp_server, 21) # connect to ftp. login (username, password) # log on.

Supplement: python blacklist Filtering

Filter words

Write the following function to add words to be filtered in the blacklist file.

# Filter def in_lists (str): str_lists = [] fd = open ('. /filter/blacklist') for line in fd. readlines (): str_lists.append (line. strip () if str in str_lists: return 0 else: return 1

It is called through the filter function provided by python. in_lists and filter functions filter out the elements in the list with a bool value of 1.

 filter( in_lists , urls )
