剛好幾個月前做過，C++ 函數裏面先加載python 腳本，再調用 裏面的 def 函數，我把代碼貼出來，你在main 函數裏面，調用getDataByScript 函數，另外相同目錄下放一個 fuckTest.py ，我是centos6.7

g++ -o test test.cpp -lpython2.7

test.cpp

#include"callPython.h"
using namespace std;
int main()

fuckTest.py

def callFuncNoArgs():
print "test.py func called !!!"
return "fuck"
