QT hybrid Python development technology: Python introduction, hybrid process and demo

Preface

Qt Medium mix Python Development , Callable Python Commands and scripts .

 

Multi person learning python, I don't know where to start .

Many people study python, After mastering the basic grammar , I don't know where to look for cases to start .

A lot of people who have done cases , But I don't know how to learn more advanced knowledge .

So for these three kinds of people , I will provide you with a good learning platform , Get a free video tutorial , electronic text , And the source code of the course ！??¤

Qt introduce Python library

According to Modularity , take python Of libs and include Copy the directory to the path of the module （ reference “ modularization ”）, modular pri The documents are as follows ：

INCLUDEPATH += $$PWD
DEPENDPATH += $$PWD
HEADERS += \
$$PWD/PythonManager.h
SOURCES += \
$$PWD/PythonManager.cpp
# python2.7.13
INCLUDEPATH += \
$$PWD/python2.7.13/include
LIBS += -L$$PWD/python2.7.13/libs
LIBS += -lpython27
