Yes indeed, high-level languages like Python *are* a radically different
programming experience than low-level languages like assembler. The
fundamental execution and data models of the languages are *very*
different:
- assembler lives in a universe of bytes and words; there are few
abstractions and you are dealing (very nearly) with the lowest
level of flipping bits in hardware, or at least of moving bytes.
- Python lives in a world of big, complex abstractions like dicts
and Unicode text and even objects as complex as "web server",
and the fundamental operations are multiple layers away from
moving bytes.
It's not surprising that this may require some re-adjustment of your
mental model of how to program.
those big complex bits cut down on the amount of code needed to achieve
a given task. :-)
It appears that I broke the code I started experimenting with, to try
changing the command, and that may have added to my confusion.
"Save As..." before engaging in big changes is your friend :-)
yes, was supposed to be a quick experiment to test idea ;)
Even better would be to learn a form of VCS (version control system)
such as Mercurial (hg) or git. Depending on the text editor you are
using, it may have VCS integration available.
I don't know anything about these tools, I use Kate as my editor for my
programming. I usually give a new number to separate versions, I'm sure
there are better ways, I just haven't gone looking for them yet. Idle
only looks useful for CLI stuff.
Off-topic:
I see you are a fellow Internode user, like me. Which part of Australia
are you in, and is your internet connection giving you as much grief as
mine is?
I have had little trouble with Internode over the last 13 years or so.
The other day is the first time I had a really slow download, went to
another mirror in Western Australia, and all went as fast as I'm
supposed to get (I have the slowest option of NBN, ( bronze 100) which I
have never NEEDED extra bandwidth, it might be nice, but I don't use the
sort of service which depends on good bandwidth, downloads can go all
night for all I care). I'm not greedy though it's all very fast compared
to dial up, or packet radio
I'm pretty sure that Internode is *grossly* oversubscribed. E.g. when I
try doing a google search, I'll usually get "Waiting for
www.google.com..." which then times out about six or twelve times on
average before succeeding to connect, after which it is damn near
instantaneous.
I search with DuckDuckGo, and rarely have any response issue with my
searches. I don't think they sell my search data.
I downloaded 2 GB of data in about ten minutes yesterday, not long
followed by a 2K email that took *three hours* to leave my computer
because the connection to Internode's mail server kept timing out.
Your connection is a bit faster than mine.
I've not experienced any speed issues with the email server.
