Last active February 8, 2017 21:38

script to sample random rows from a file (typically csv) with a given probability

	#!/usr/bin/env python3

	# Sample random lines from a file on standard input, writing to standard output
	# first command line argument is probability with which to return a row that is read
	# second command line argument is something evaluating to a boolean indicating whether the file has a header
	# if True, the header (first line) will always be sent through to the output
	# third command line argument will manually set the seed if present so as to make the results reproducible,
	# else seed will come from OS-determined random source

	# Usage:
