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
