基于Python实现Ftp文件上传,下载
测试环境：
Ftp客户端：Windows平台
Ftp服务器：Linux平台
Python版本：Python 2.7.6
实现功能：
支持FTP文件上传、下载，可以上传目录(分区除外)，也可以上传单个文件；可以下载整个目录(/根目录除外)，也可以下载单个文件
实践代码：
#!/usr/bin/env python

# ftp.download_dir('E:/', '/home/testacc')
ftp.download_file('E:\\', '/home/testacc/testfile')
ftp.quit()
ftp.conf配置如下：
[FTP]
ftp_host = 192.168.1.103
ftp_port = 21
ftp_user = testacc
ftp_passwd = testacc
