Hobbyist - Python vs. other languages

[fprintf]

I have been playing with computers since I first learned to program
moving shapes on an Atari 800XL in BASIC. After many years of dabbling
in programming languages as a hobbyist (I am not a computer scientist
or other IT professional), I have never found a way to stick with a
language far enough to do anything useful.  I learn all about loops
and data structures and functions/methods etc. but never get to create
a program that will do anything of value that I can't more easily do
via freeware. Well, except the slot car timing system I wrote in C++
for Linux many moons ago.

Honestly Python seems like a breath of fresh air and possibly a way to
get back to my BASIC roots, you know, programming just for the fun of
it.

Since I don't have a specific problem to solve, besides
Pythonchallenge (which I found very cryptic), and Project Euler (which
I found beyond my mathematics skills), is there a place to go for
increasingly difficult problems to solve? I have followed a number of
the recommended online tutorials that contain a logical progression of
problems and yet they all end at the point where a person has enough
knowledge of the syntax, but not really enough to do anything.
