The use of template engines is unavoidable and necessary in web development. The hi.py framework uses JINJA2 as the template engine.To use the JINJA2 engine provided by hi.py, you first need to introduce it: from Import Hi,templateThen it is used:1@app. Route (R'^/template/(? p',['GET'])2 defTPL (req,res,param):3param['title']='JINJA2 Test'4Tpl_engine = Template (Os.path.join (OS.GETCWD (),'python/templates

)return False and _entermouseevent in the stage are very similar. The _ismouseon method of the child object is used to determine whether to click on the object. __dispatchmouseevent is used to trigger mouse events. __getvisualcoordinate is used to get a display coordinate, which is like looking at a three-dimensional graphical visualization, and the actual size is not the same as what we see. So we use this method to achieve the size and position we see. __getvisualcoordinate Code: def
