Python writes some of the problems encountered by the DOS compression example

In the case of completing the backup_ver1.py, there are several problems encountered.

1. The tutorial is compressed with zip, and the native is not installed Zip,dos cannot execute the zip command.

Solved: Replace the rar command execution, which will C:/Program Files/winrar under the Rar.exe copy to%systemroot%/system32, so you do not have to set the environment variable RAR, and can directly re-cmd Use the RAR command at the command prompt.

2. The folder path used as an example contains spaces, and DOS does not correctly identify the compression path.

Solved: In the form of a compression path, add the "" character before and after the path, and note the ' \ ' escape character.
