Basic IPC demo with non-parent-child relationship in Python

	#!/usr/bin/env python3
	'''
	This script demonstrates some basic inter-process communication. Typical usage:

	1. Run this script with the "make" argument. On Windows, a new console window
	will appear; that is the worker. Copy the last line of the output from this
	window to the clipboard.
	2. Run this script with the "query" argument and paste the last line of the
	output from the last step as the second argument. Repeat this step as many
	times as you want. After the worker finishes, repeating this step will cause

This script finds a password of printable ASCII characters given a desired sum and product of the ASCII character codes in the password.

	#!/usr/bin/env python3

	Z3 has no way of arbitrarily getting a character at an index from a string.

wecsam / filetype.py

Created December 3, 2018 01:29

This class is like argparse.FileType, except that it supports all keyword arguments for open() and returns a function that opens a handle rather than returning the handle itself.

	#!/usr/bin/env python3
	import argparse, gettext, sys

	class FileType(argparse.FileType):
	'''
	This class is just like argparse.FileType, except that it supports all
	keyword arguments for open() and returns a function that opens a handle
	rather than returning the handle itself. This means that the file is not
	actually opened until that function is called. This also means that the
	result can be used with a "with" block.
