Well, here is that one person. ;-)
I'm an entirely self-taught amateur/hobbyist programmer, coming to Python from a C background.
Very early in my reading of books/tutorials on Python I learned that Python variables are
different, and how they are different from C variables. Essentially I said, "Okay, they're
different. What's next?" There was no confusion at all. All I had to do was accept that they
_are_ different. (BTW, I'm now quite hooked on Python -- and still learning it.)

As I said above, not a problem. I already accepted the fact that all programming languages are
different -- often with similarities, but more often quite different, especially in the details.
So when programming in C I think in C-style variables, in Python I think in Python-style
variables. And uv course, I nefer make mmistakes... Yeah, right! ;-)

This is something I absolutely disagree with. I still think it's only necessary to teach that
variables in different languages are handled differently. Insisting on a different name is NOT
helpful. And insisting that Python does not have variables is ludicrous!
