Transforming Code into Beautiful, Idiomatic Python

Notes from Raymond Hettinger's talk at pycon US 2013 video, slides.

The code examples and direct quotes are all from Raymond's talk. I've reproduced them here for my own edification and the hopes that others will find them as handy as I have!

Looping over a range of numbers

for i in [0, 1, 2, 3, 4, 5]:

• Check if italic font is supported:

$ echo -e "\e[3mitalic\e[23m"

• Also check:

$ infocmp $TERM | grep sitm
 sgr0=\E(B\E[m, sitm=\E[3m, smacs=\E(0, smam=\E[?7h,

# - cron with cleanup of timedout clients, automatic dump
# - the dump should use array startsearch to write it line by line
#   and may just use gets to read element by element and load the whole state.
# - 'help','stopserver','saveandstopserver','save','load','reset','keys' commands.
# - ttl with milliseconds resolution 'ttl a 1000'. Check ttl in dump!

1. Create a service file like dash_sniffer.service
2. Put it in /lib/systemd/system/
3. Reload systemd using command: systemctl daemon-reload
4. Enable auto start using command: systemctl enable dash_sniffer.service
