This constructor should always be called with keyword arguments. Arguments are:
group should be None; reserved for future extension when a ThreadGroup class is implemented.
target is the callable object to be invoked by the run() method. Defaults to None, meaning nothing is called.
name is the thread name. By default, a unique name is constructed of the form « Thread-N » where N is a small decimal number.
args is the argument tuple for the target invocation. Defaults to ().
kwargs is a dictionary of keyword arguments for the target invocation. Defaults to {}.
If a subclass overrides the constructor, it must make sure to invoke the base class constructor (Thread.__init__()) before doing anything else to the thread.

- run()#
Starts the server.
- shutdown()#
Shuts down the server, the function could work if:
method run keeps a pointer on a server instance (the one owning method serve_forever)
module werkzeug returns this instance in function serving.run_simple
module Flask returns this instance in method app.Flask.run
- ensae_teaching_cs.td_1a.flask_helper.Text2Response(text)#
Converts a text into plain text.
- Paramètres:
text – text to convert
