Time how long, on average, it takes to call time.time(), using only time.time() to measure.

	#!/usr/bin/env python3
	from time import time

	# If we iterate a million times,
	# then results per-call are in micro seconds.
	ITERS = 1_000_000
	UNIT = "µs"

	# If our first loop below ONLY measures calls to time(),
	# then the second loop below (which is to measure loop overhead)

tartley / exitval in ps1

Created July 10, 2012 14:22

prepend a red 'last command exit value' to PS1, only for non-zero values.

	# display red exit value if it isn't zero
	PROMPT_COMMAND='EXITVAL=$?; '$PROMPT_COMMAND
	GET_EXITVAL='$(if [[ $EXITVAL != 0 ]]; then echo -n "\[\e[37;41;01m\] $EXITVAL \[\e[0m\] "; fi)'
	export PS1="$GET_EXITVAL$PS1"
