python version:
python3 该代码用于加密python3编写的代码,将.py文件转换成.so文件，达到加密的效果
python2 该代码用于加密python2编写的代码,将.py文件转换成.so文件，达到加密的效果
Options:
-h, --help 显示帮助
-d, --directory 你需要加密的文件夹
-o, --operation 你所需要执行的操作,python3 or python2 or model
-f, --file 加密单个py文件
-c, --clear 删除原始的py文件
-m, --maintain 列出你不需要加密的文件和文件夹，如果是文件夹的话需要加[]
例子: -m __init__.py,setup.py,[poc,resource,venv,interface]
-z, --zip 加密之后压缩文件
Example:
python setup.py -f test_file.py -o python2 加密单个文件
python setup.py -d test_dir -o python2 -m __init__.py,setup.py,[poc/,resource/,venv/,interface/] -c 加密文件夹
python3 setup.py -f test_file.py -o python3 加密单个文件
python3 setup.py -d test_dir -o python3 -m __init__.py,setup.py,[poc/,resource/,venv/,interface/] -c 加密文件夹
