[英]how to pass a value to c++ from python and back?
i would like to pass values from python to a c++ program for an encryption from inside a python program and then return the value from there to the python program . 我想将值从python传递到c ++程序,以便从python程序内部进行加密,然后将值从那里返回到python程序。 how to do it?
怎么做?
If you want to use some existing Unix-style command line utility that reads from stdin and writes to stdout, you can use subprocess.Popen
by using Popen.communicate()
: 如果你想使用一些现有的Unix风格的命令行工具,从标准输入读取和写入到stdout,你可以使用
subprocess.Popen
通过Popen.communicate()
import subprocess
p = subprocess.Popen(["/your/app"], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
output = p.communicate(input)[0]
As said msw in the other post, the proper solution is using PyObject. 正如另一篇文章中所说的msw,正确的解决方案是使用PyObject。 If you want to have a two-way communication between C++ & Python, Boost Python would be interesting for you.
如果你想在C ++和Python之间进行双向通信,Boost Python对你来说会很有趣。 Take a look at website Boost Python ,
看看Boost Python网站,
