It is important to look beyond your own comfort zone to see what other languages can support: [WayBack] Forde’s Tenth Rule, or, “How I Learned to Stop Worrying and ❤ the State Machine”.
The article is about implementing finite state machines in JavaScript with as little usage of string literals as possible.

Cool example, which requires dnspython and might need an update of the DNS record type list (maybe dnspython has that list built in?):

On Mac OS X with stock Python:
All you need to do is
sudo easy_install pip
After this, you might want to upgrade pip:
sudo pip install --upgrade pip

You could go the homebrew way, but that means your system will have two Python installations usually causing a nightmare of path dependency orders. In addition, homebrew puts you on the wrong foot, so:
DO NOT DO THIS!
# brew install pip Error: No available formula with the name "pip" Homebrew provides pip via: `brew install python`. However you will then have two Pythons installed on your Mac, so alternatively you can install pip via the instructions at: https://pip.readthedocs.io/en/stable/installing/

From [WayBack] bash – How to add a progress bar to a shell script? – Stack Overflow (thanks Mitch Haile!):
You can implement this by overwriting a line. Use
\rto go back to the beginning of the line without writing\nto the terminal.Write
\nwhen you’re done to advance the line.Use
echo -neto:
- not print
\nand- to recognize escape sequences like
\r.Here’s a demo:
echo -ne '##### (33%)\r' sleep 1 echo -ne '############# (66%)\r' sleep 1 echo -ne '####################### (100%)\r' echo -ne '\n'
