Context-managed, iterable, in-memory file

	from StringIO import StringIO


	class MemoryFile(StringIO):
	"""
	This abstraction provides context management and line-iteration over the
	built-in StringIO class, making it more fully behave like a file object.
	Unfortunately, iteration is not (yet?) memory-efficient for large files.
	"""
	def __init__(self, text=''):

mdwhatcott / read_parallel.py

Created May 25, 2012 21:05

Read any number of files in parallel.

	FIRST = 'path to first file'
	SECOND = 'path to second file'


	def main():
	with open(FIRST) as first, open(SECOND) as second:

Last active February 23, 2019 23:08

Chunks the bit groupings in bytes if the specified length is divisible by 8.

	def main():
	print ' 42 in 32 bits:', bits(42, 32)
	print '-42 in 32 bits:', bits(-42, 32)
	print '-42 in 20 bits:', bits(-42, 20)
	print


	def bits(number, size_in_bits):
	"""
	The bin() function is REALLY unhelpful when working with negative numbers.

mdwhatcott / logger.py

Created June 13, 2013 15:28

Write log messages to the console (sys.stdout) and to a log file, all managed as a context manager.

	import sys


	class Logger(object):
	"""
	Write log messages to the console (sys.stdout) and to a log file,
	all managed as a context manager:

mdwhatcott / mnemonic.py

Last active January 2, 2016 01:29

Here's some Python code to convert a passage of text into first-letter sequences to facilitate memorization:

	def first_letter_mnemonic(text):
	words = text.split()
	letters = []
	for word in words:
	letters.append(word[0])

	if word[-1] in ',-': # inline punctuation
	letters.append(word[-1])

	elif word[-1] in '.;:?!': # delimiting punctuation

mdwhatcott / goconvey-v2-example.go

Last active January 4, 2016 07:59

Detailed example of the 2.0 update to GoConvey

	// NOTE: This is examples code which never actually became valid because we found a better way.

	func TestScoring(t *testing.T) {
	Convey("Subject: Bowling Game Scoring", t, func(c Context, so Assertion) {
	var game *Game // Whatever you do, don't do this: game := NewGame()
	// Otherwise nested closures won't reference the correct instance

	Convey("Given a fresh score card", c, func() {
	game = NewGame()

mdwhatcott / auto-run.py

Created February 20, 2014 05:41

Auto-run `go test` in the console

	#!/usr/bin/env python

	"""
	This script scans the current working directory for changes to .go files and
	runs `go test` in each folder where *_test.go files are found. It does this
	indefinitely or until a KeyboardInterrupt is raised (<Ctrl+c>). This script
	passes the verbosity command line argument (-v) to `go test`.
	"""

mdwhatcott / Iterative_example_test.go

Created February 28, 2014 05:20

Example of using table-driven testing with GoConvey (also shows how to use `Reset`)
