Lines Of Code (LOC) (Python)

2016-10-25T17:53:01-07:00

Python recipe 580709 by Jean Brouwers (count, lines, python2, python3, source). Revision 3.

LRU dictionary (Python)

2016-04-17T01:22:01-07:00

Python recipe 580644 by Felix (dict, dictionary, expiration, expiring, lru, lru_cache, python3).

For most cases where you want to store a limited amount of data, functools.partial is sufficient. However, if you want or need more control over your data, especially specifying an expiration date for your entries, this can come in handy.

Read the docstrings for implementation details.

Mandelbrot Set made simple (Python)

2015-12-28T17:56:08-08:00

Python recipe 579143 by Jack Trainor (educational, fractal, graphics, mandelbrot, mathematics). Revision 2.

This is a mini-framework for exploring the Mandelbrot Set.

It outputs to a Tkinter window or to a PNG file (Pillow package required). It includes a disk caching mechanism for saving and later retrieving Mandelbrot calculations to avoid recalculating the Set on each run.

See module documentation for further information. Compatible with Python 2 and 3.

Tail multiple pidgin IRC logfiles (Python)

2015-06-06T12:13:00-07:00

Python recipe 579066 by Anton Vredegoor (colorize, irc, iterators, logfiles, merging, nonblocking, pidgin, tail, threads). Revision 2.

Tail multiple pidgin IRC logfiles.

Pidgin should be connected to IRC with the channels one wants to tail joined, and it should save logs as text.

The script needs two arguments:

the directory containing the directories with channel logs

a list of channel names, quoted and separated by spaces

Example command:

python pidgin-irctail.py -d ~/.purple/logs/irc/YOUR_IRC_HANDLE@irc.freenode.net -c "#chan1 #chan2 #chan3"

Some text elements are higlighted, and channel names are inserted into the log lines after the time info.

If more than one channel is entered, the output of the logs is merged.

TicTacToe (Python)

2014-12-14T16:23:44-08:00

Python recipe 578980 by Malcolm Jeremy Lewis (tic).

Wait for network service to appear (Python)

2014-11-06T07:29:12-08:00

Python recipe 578955 by Mohammad Taha Jahangir (network, socket).

This script allows you to wait until specified port is opened on remote server. This can be useful in automation jobs - restarting server, wake on lan etc. It can also be used for monitoring distant service/site.

The main problem that this script solves is that you need to handle two different timeouts when opening probing socket, and it is not described in python documentation. See http://bugs.python.org/issue5293 for more information.

Analog Clock (Python)

2014-05-14T20:53:39-07:00

Python recipe 578875 by Paulo Cavalcanti (clock). Revision 3.

Python Awesome DD (Python)

2014-07-12T07:29:59-07:00

Python recipe 578907 by Mike 'Fuzzy' Partin (curses, dd, file, input, output, progress_bar). Revision 3.

Imagine if the *nix utilities 'dd', 'wget', and 'pv' had a baby. That baby would be named 'padd'. A 'dd' replacement (most commonly used options translate with no problem), that gives progress output like 'pv' and supports (currently) http(s) and ftp input sources, with more planned (sftp for one). Output support for ftp, sftp, and http(s) is also planned.

Monitor Progress of File Descriptors of Another Process (Python)

2014-05-30T01:10:53-07:00

Python recipe 578882 by Alfe (file_descriptor, monitor, prediction, proc, process, progress, watch).

This tool (inspired by azat@stackoverflow, see http://stackoverflow.com/a/16082562/1281485) allows to watch the progress of the file descriptors of another process. This can be used, for example, if you transfer a file to another host and the transferring program does not show any progress indication itself. Instead of waiting blindly until the routine is done, with this tool you can use Linux's proc file system to monitor the progress of the other process while it walks through the file.

The tool continuously monitors the position in and the size of the files the given process's file descriptors point to. For growing (or shrinking, but that's very unusual) files, a time when it was (or will be) empty is computed ("emptyTime"), for moving file descriptors (the typical case), the time when it started at position 0 ("startTime"), the time when it will reach the current size of the file ("reachTime") and when it will meet with the end of a growing (or shrinking) file is computed ("meetTime").

For fixed-size files the meetTime will be the same as the reachTime of course. The meetTime only makes sense in case a file is growing and at the same time read (e. g. when a movie is downloaded to a file by one process and converted by a different process; using this tool can tell you when the converter process might run dry on the input because the download wasn't fast enough, and in this case you maybe can pause the converter to prevent this situation).

The tool is designed as a library; the display of the information is independent from the gathering of the data. Please feel free to create more fancy displays, add percentage output etc.

A DEMO to show how to write text into the Python terminal Title Bar... (Python)

2013-09-17T17:55:53-07:00

Python recipe 578662 by Barry Walker (apple, bar, cygwin, demo, linux, macbook_pro, title, title_bar).

This DEMO is show how to write some text of your choice into the Title Bar of the Python terminal window.

Firstly it imports "time" just for this demo so that a simple time delay can be generated. Next the Python terminal window is written to for the 5 seconds of delay; see code. And finally the Title Bar is restored to normal...

A snapshot image can be seen here:-

FreshFish (Python)

2013-12-29T15:38:33-08:00

Python recipe 578800 by Justin Shaw . Revision 2.

FreshFish is a function decorator for functions with no arguments (hardware query).

The first time the function is called, the wrapper caches the result (the fish). Subsequent calls to the wrapped function simply return the cached result as long as the fish is still fresh. When the fish goes stale, FreshFish calls the underlying function again for FreshFish.

I used this on a BeagleBone project to monitor heart rate, speed, and cadence.

Stopwatch with laps in Tkinter (Python)

2013-09-19T18:42:10-07:00

Python recipe 578666 by Frederico (tkinter). Revision 3.

This is a small implementation of a stopwatch widget in Tkinter. The widget displays a label with minutes:seconds:1/100-seconds. The label is updated every 50 ms, but that can easily be changed. Methods are availble for starting, stopping and resetting the stopwatch. A simple program demonstrates the widget.

A Simple Timing Function (Python)

2013-12-01T01:39:44-08:00

Python recipe 578776 by Mike Sweeney (performance, timing). Revision 2.

This function prints out a message with the elapsed time from the previous call. It works with most Python 2.x platforms. The function uses a simple trick to store a persistent variable (clock) without using a global variable.

Python 3 Token Bucket (Rate Limit) (Python)

2013-09-16T23:41:46-07:00

Python recipe 578659 by Esteban Castro Borsani (bucket, limit, rate, ratelimit, token, tokenbucket).

A thread safe implementation.

Shortest Common Supersequence algorithms (Python)

2013-10-02T12:52:23-07:00

Python recipe 578678 by Rutger Saalmink (approximation, bound, breadth_first_search, common, depth_first_search, sequence, shortest, super).

The Shortest Common Supersequence (SCS) problem is an NP-hard problem (https://en.wikipedia.org/wiki/Shortest_common_supersequence), which occurs in problems originating from various domains, e.g. Bio Genetics. Given a set of strings, the common supersequence of minimal length is sought after. Below a set of algorithms is given, which I used in approximating and/or backtracking the optimal solution(s).

Run some command every x seconds (Python)

2013-09-24T13:26:19-07:00

Python recipe 578673 by Rutger Saalmink (command, iterative, os, run).

Sometimes it comes in handy to run some command every minute or hour. For example, have some process check your ip address every minute with 'ifconfig' or run some purgescript at midnight through 'sqlplus.exe @purge_aux_table'.

Primitive Peer to Peer Chat (Python)

2013-07-07T02:09:57-07:00

Python recipe 578591 by teddy_k (chat, peer, select, socket, threading).

This took me longer than it should have. I am putting it here in the hopes that this post will spare others from having to Google things for extended periods of time.

In short, you either listen for a connection (Chat_Server), or connect to a remote IP address (Chat_Client). From there, you can send text strings back and forth.

This is a bit rough-hewn, obviously; I apologize in advance.
