Re: A question on modification of a list via a function invocation
Here is my attempt to clarify the situation with some ascii graphics. (Well, not ascii, but utf-8 box-drawing characters — I hope they come through ok. And, of curse, it won't display properly with a proportional font.) Here's a VERY useful tool for understanding/explaining/drawing such code snippets: - http://pythontutor.com At the "Edit code" link, you can type/paste your own Python statements and have the tool single-step though them. At each step, it draws the data structures with values, links to other data structures, etc. A great Python visualization tool!

Considering a career change down the road and have been wondering... What are the job prospects for a middle age entry level programmer. Just trying to get a better understanding where I stand career wise. Appreciate all feed back. Thanks! Are you asking about job prospects based on experience with Python vs other languages? If so, here's a site that shows the relative demand for various programming languages over time. Based on its huge database of job listings. Also shows the relative supply of programmers in various languages over time. You can specify which languages or other marketable skills to show in the graph: - [2]https://www.indeed.com/jobtrends/q-python-q-ruby-q-php-q-javascript-q-java-q-perl.html Hope this helps, --Fred -- Fred Stluka -- [3]mailto:f...@bristle.com -- [4]http://bristle.com/~fred/ Bristle Software, Inc -- [5]http://bristle.com -- Glad to be of service!

How do I specify the number of columns when using "C-x $"? You will remember, from doing the Emacs tutorial when you first learned Emacs, that all commands have a “prefix argument” available <URL:https://www.emacswiki.org/emacs/PrefixArgument> that the command can use to modify its behaviour. So, use the prefix argument to specify the number of columns for ‘set-selective-display’. E.g.: M-9 C-x $ # Indentation >= 9 disappears. C-u C-x $ # Indentation >= 4 disappears. C-u 1 3 C-x $ # Indentation >= 13 disappears. C-u C-u C-u $ # Indentation >= 64 disappears. C-x $ # All lines reappear. etc. Same for using the command at the M-x prompt. I type "M-x" and see the M-x prompt, then then type "set-selective-display" using tab to autocomplete it. But I can't then type a column number after a space or in parens or anything. What am I missing? Time to work through the Emacs tutorial again; ‘C-h t’ :-) -- https://mail.python.org/mailman/listinfo/python-list
Re: Scala considering significant indentation like Python

The command is bound to ‘C-x $’ in default Emacs. Ben, How do I specify the number of columns when using "C-x $"? It doesn't prompt, and doesn't seem to take the current column of the cursor position into account. Just echoes: selective-display set to nil. Same for using the command at the M-x prompt.

Recommended courses/materials for Python/Django course...
Python programmers, Any Python and/or Django courses/materials to recommend? I may be teaching a Python/Django class soon. My client may be willing to jumpstart by buying existing course materials (lecture slides, notes, homeworks, labs, reference links, any other materials). We'll certainly be happy to make use of any free materials. Do you have any Python and/or Django courses/materials to recommend?
