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 578208 by Stephen Chappell (archive, human, old, populate, simulation). Revision 2.

Subprocess with async I/O pipes class (Python)

2009-05-17T02:02:04-07:00

Python recipe 576759 by Mike Kazantsev (asynchronous, ipc, non_blocking_i_o, pipe, subprocess). Revision 2.

Just stumbled upon the need to move data chunks between subprocesses in a non-linear way with some logic in-between, so tee(1) and fifo(7)'s weren't too good option. Inspired by 440554, but rewritten from scratch to remove unnecessary delays due to sleep(3) calls and suboptimal try/sleep-based polling.

A Python script to test download mirrors (Python)

2004-05-19T21:28:55-07:00

Python recipe 284631 by Tim Lesher (web). Revision 2.

Bandwidth testing is easy with Python's built-in web access, HTML parsing, and threading modules.

When Fedora Core 2 was released, I wanted to find which download mirror would be fastest when I tried downloading the CD images. It only took about an hour to whip up this mirror bandwidth tester.

This script demonstrates web download, HTML parsing, and some interesting threading issues.
