Recently, demand is the need to address the other pictures on the ftp to provide access to the local server, originally planned thinking is to use shell operations, because the shell itself also supports ftp commands in a for loop can achieve demand. But then thinking about or take python operation; then proceeds Baidu online; without exception, was so disappointed to not be directly copied to use. Thus in a modified code. Still a little heart to learn things; as long as the specific operation code ftp account password has been modified to use the corresponding directory
It should be noted at this point to note is os.path.join usage
