linux qt 调用python简单例子

1、安装python并查看python安装路径，配置qt的pro文件

sudo apt-get install python-dev否则#include <Python.h> 文件提示找不到

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = untitled
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

DISTFILES += \
    zytest.py

INCLUDEPATH += -I /usr/include/python2.7
LIBS += /usr/lib/i386-linux-gnu/libpython2.7.so.1

2、qt新建python测试文件

3、添加Python.h头文件,输入一下测试代码

    Py_Initialize();
    if (!Py_IsInitialized()) {
        return;
    }

    PyRun_SimpleString("import sys");
    PyRun_SimpleString("sys.path.append('./')");

    PyObject* pModule = PyImport_ImportModule("zytest");
    if (!pModule) {
        qDebug()<<"cant open python file";
        return;
    }

    PyObject* pFunHello = PyObject_GetAttrString(pModule,"hello");
    if (!pFunHello) {
        qDebug("get function hello failed");
        return;
    }

    PyObject_CallFunction(pFunHello,NULL);
    Py_Finalize();

 

4、将之前建立的.py 文件放到可执行文件同级目录

5、运行显示调用成功
