我有以下代码,可以轻松连接到FTP服务器并打开一个zip文件.我想将该文件下载到本地系统.怎么做？
# Open the file for writing in binary mode
print 'Opening local file ' + filename
file = open(filename, 'wb')
# Download the file a chunk at a time
# Each chunk is sent to handleDownload
# We append the chunk to the file and then print a '.' for progress
# RETR is an FTP command
print 'Getting ' + filename
ftp.retrbinary('RETR ' + filename, handleDownload)
# Clean up time
print 'Closing file ' + filename
file.close()
