Whoops, thanks for the reminder Mark.
So what for the Request is used for then?
In general when you see that something in Python starts with a capital
letter, that indicates a class. Check out the relevant section of the PEP8
coding style [1], this is a good reference to have on hand. (This
generalization doesn't apply to builtin types which follow a separate
convention, also outlined in [1] -- and of course there are a numerous
exceptions.)
This holds for your variable in question "request" which is an instance of
the Request class. Check out [2] for more information on this. PyCharm
tries to do its best but I've had this problem too. You can always open up
a python REPL and look at the object yourself:
>>> import flask
>>> r = flask.Request
>>> r
<class 'flask.wrappers.Request'>
>>> dir(r)
and so on. When I'm working in python I like to keep one of these open for
this purpose.
HTH,
