给用ps做的网站加div营业推广怎么写

1.为什么要将python打包为.so文件？

保护源码

2.实战例子

a.安装相应的包

pip install cython

 验证安装是否成功

cython --version

b.实战的文件目录和内容 

hi.py

# This is a sample Python script.# Press Shift+F10 to execute it or replace it with your code.
# Press Double Shift to search everywhere for classes, files, tool windows, actions, and settings.def print_hi(name):# Use a breakpoint in the code line below to debug your script.print(f'Hi, {name}')  # Press Ctrl+F8 to toggle the breakpoint.# Press the green button in the gutter to run the script.
if __name__ == '__main__':print_hi('PyCharm')# See PyCharm help at https://www.jetbrains.com/help/pycharm/

hello.py

def hello(name):print("hello " + name)

bye.py

def bye(name):print("bye " + name)

 setup.py

把需要转换的py文件都放进去

from distutils.core import setup
from Cython.Build import cythonize
setup(ext_modules = cythonize(["hi.py", "hello.py", "bye.py"]))

terminal运行命令

python setup.py build_ext

 运行log

 运行结果

 可以发现多了几个.c文件和build文件夹

build文件夹中

 

复制到根目录

 

在根目录里， 写一个demo.py

from hi import print_hi
from hello import hello
from bye import byeprint_hi("K.D.")
hello("LeBron")
bye("Kobe")

 运行

Hi, K.D.
hello LeBron
bye KobeProcess finished with exit code 0

 把hi.py,hello.py,bye.py删除，再执行demo.py，可以得到同样的结果

即  此时已经使用到了.so文件，而不是原来的.py文件

如果.py在不同文件夹中，则在不同文件夹里面执行类似操作。

待续。。
