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
