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.
