Generate a PDF cheat sheet for converting 0 to 255 between bin / oct / dec / hex (Python)

2016-10-10T20:40:48-07:00

Python recipe 580706 by Vasudev Ram (binary, conversion, decimal, hexadecimal, octal, pdfwriter, pdf_generation, python, utility, xtopdf).

This recipe shows how to generate a PDF cheat sheet, that contains a table for conversion of the numbers 0 to 255 (the numbers that can fit in one byte) between binary, octal, decimal and hexadecimal representations. The table has four columns, one for each of those bases, and 256 rows, for the numbers 0 to 255.

TO use the table, you can look for a number, say in decimal, in the Dec(imal) column (or use the search function of your PDF viewer), then when you find it in some row, just look at the other 3 columns in that row, to find the value of that number in binary, octal and hexadecimal. And use the same procedure if starting with a number in any of the other three bases.

Process Delimiter-Separated Values data with Python (Python)

2016-11-24T23:57:35-08:00

Python recipe 580722 by Vasudev Ram (command, commandline, data, dsv, file, python, utilities, utility).

This recipe shows how to read and process delimiter-separated values (DSV) data with a Python command-line program. It provides two ways of specifying the delimiter character, by an ASCII character or an ASCII code, which makes it more flexible than allowing only a character. It allows the DSV data to be specified as one or more filenames on the command line, or given via the standard input of the program.

Python recipe 580619 by Jack Trainor (drives, files, utility).

As one accumulates multiple drives, hard and flash, containing, thousands even millions of files, it becomes useful to have a text file containing an alphabetized catalog list of all files and their locations by drive and directory.

The list can be searched by eye or by an editor to locate particular files.

The list can also be loaded into a script to be filtered programmatically as desired.

Python recipe 578154 by Stephen Chappell (delete, directory, file, gui, utility). Revision 2.

Module providing GUI capability to prune any directory.

The code presented in this module is for the purposes of: (1) ascertaining the space taken up by a directory, its files, its sub-directories, and its sub-files; (2) allowing for the removal of the sub-files, sub-directories, files, and directory found in the first purpose; (3) giving the user a GUI to accomplish said purposes in a convenient way that is easily accessible.

Custom Windows Alarm Clock (Python)

2012-07-10T17:27:48-07:00

Python recipe 578204 by Stephen Chappell (alarm, archive, clock, old, utility).

After writing a few alarms using winsound.Beep, desire to expand into other sound possibilities led to the writing of this program using winsound.PlaySound. The sounds are stored in a custom format (some experimentation in archiving files). This is committed for archival to be run under Python 2.5 or later versions.

Zero (Batch) Programs (Python)

2012-07-10T12:37:37-07:00

Python recipe 578205 by Stephen Chappell (archive, batch, old, processing, utility). Revision 2.

Having written many programs that work with groups of files, the zero programs were written based on a simple batch engine in the zero utility. All of the other programs import the first program to take advantage of its batch processor while supplementing there own functionality in place of zeroing out file data. This is committed for archival to be run under Python 2.5 or later versions.

Setting Namespaces (Python)

2012-07-05T02:39:42-07:00

Python recipe 578195 by Stephen Chappell (helpers, library, options, utility). Revision 2.

Provides a simple way to deal with program variable versioning.

This module defines two classes to store application settings so that multiple file versions can coexist with each other. Loading and saving is designed to preserve all data among the different versions. Errors are generated to protect the data when type or value violations occur.

Linux to Windows (Python)

2012-07-04T01:18:50-07:00

Python recipe 578192 by Stephen Chappell (archive, commandline, old, utility).

When trying to work with Linux archive downloaded onto Windows, sometimes it is helpful to untar all found archives, give extension-less files the "txt" extension, and convert text files to Windows line endings (\r\n), and that is just what this program is designed to accomplish. This is committed for archival to be run under Python 2.5 or later versions.

Settings Organizer (Python)

2012-07-04T22:16:36-07:00

Python recipe 578173 by Stephen Chappell (helpers, library, options, utility). Revision 3.

Provide an easy method to manage program options among multiple versions.

This module contains two classes used to store application settings in such a way that multiple file versions can possibly coexist with each other. Loading and saving settings is designed to preserve as much data between versions. An error is generated on loading if saving would lead to any data being lost.
