'''
The second script is to automatically create the ftp user and password, reduce the operation and maintenance of the ftp operation, and use it for the xx department.
When there is a new directory under the ftp root directory, the directory is automatically converted into an account and password
The pinyin module converts Chinese characters into pinyin for ftp users and passwords
How to use:
1: For the first time, you can create an administrator account and point to the ftp root directory
2: Use the administrator account to add a directory to the root directory, and then this script automatically creates a user to point to the directory
