Don't declare like that - just start using it, and see what you think
:) But I would be very much surprised if Python doesn't get added to
your toolbelt. A good programmer should always keep a selection of
tools handy - seldom is one tool the right one for every job.

Do I really need PyPi or other external stuff for this? Is Python well equipped for this?
You could do all of that with just the standard library, but then your
only choice of GUI library is Tkinter, which is derived from Tcl/Tk.
If you don't like how that looks (either in your code, or in the
resulting GUI), you'll need to turn to PyPI for an alternative (eg
something derived from GTK or wxWindows or Qt). I'm not sure how the
graphing capabilities of Tkinter are, so you might want to grab
matplotlib too - again, it'll give you a lot more flexibility than you
would have if you restrict yourself to *just* the standard library.
But I think you could do all of that - certainly most of it - with
just the language and standard library.

Reading and writing text files is easy, as is basic mathematics.
You'll have that down in an hour or two, most likely, and then you'll
have time to play GUIs.

Those things will most likely require external libraries. But most of
them are probably possible.
