</p>
<p>This recipe shows how to create a utility like Unix seq (command-line), in Python.
seq is described here: </p>
<p><a href="https://en.wikipedia.org/wiki/Seq_%28Unix%29" rel="nofollow">https://en.wikipedia.org/wiki/Seq_(Unix)</a></p>
<p>but briefly, it is a command-line utility that takes 1 to 3 arguments (some being optional), the start, stop and step, and prints numbers from the start value to the stop value, on standard output. So seq has many uses in bigger commands or scripts; a common category of use is to quickly generate multiple filenames or other strings that contain numbers in them, for exhaustive testing, load testing or other purposes. A similar command called jot is found on some Unix systems.</p>
<p>This recipe does not try to be exactly the same in functionality as seq. It has some differences. However the core functionality of generating integer sequences is the same (but without steps other than 1 for the range).</p>
<p>More details and sample output are here:</p>

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

</p>
<p>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.</p>
<p>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.</p>
Process Delimiter-Separated Values data with Python (Python)

</p>
<p>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.</p>

</p>
<p>This recipe shows how to create a simple version of the Unix split command in Python. The split command splits an input file into multiple smaller files, the size of each of which is specified by a command-line argument giving the number of lines per file. This is useful for multiple purposes, such as editing large files in pieces, backing up files to small capacity storage devices, sending files across the network, etc.</p>

</p>
<p>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.</p>
<p>The list can be searched by eye or by an editor to locate particular
files.</p>
<p>The list can also be loaded into a script to be filtered
programmatically as desired.</p>

<p>After writing a few alarms using <code>winsound.Beep</code>, desire to expand into other sound possibilities led to the writing of this program using <code>winsound.PlaySound</code>. 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.</p>
