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.

Validate data easily with JSON Schema (Python)

2015-12-06T21:23:48-08:00

Python recipe 579135 by Vasudev Ram (data, json, jsonschema, python, python2).

This recipe shows how to use the jsonschema Python library, which implements the JSON Schema specification, to easily validate your Python data. It sends good output to stdout and bad output to stderr, for demo purposes.

jsonschema Python library: https://pypi.python.org/pypi/jsonschema

data_dump.py, like the Unix od (octal dump) command (Python)

2015-11-01T12:43:38-08:00

Python recipe 579120 by Vasudev Ram (data, dump, hexadecimal, linux, octal, od, representation, unix, utility, windows).

This recipe implements a simple data dump tool, roughly like the od command of Unix, which stands for octal dump (though od can also dump data in hex and other formats). This tool dumps data in character and hex formats, in this version. This is data_dump.py version 1.

Data (A Class For Arbitrary Data) (Python)

2015-08-03T15:22:40-07:00

Python recipe 579092 by Alfe (class, data, lightweight).

A class which is designed to be easy to use when one needs a piece of data with a minimum of source required.

Usage:

shop = Data(owner="Homer", address="down the street", ice=Data(flavor="vanilla", amount=3))
print shop
Data:
  owner = 'Homer'
  ice = Data:
          amount = 3
          flavor = 'vanilla'
  address = 'down the street'

Kids Level Analogue Data Logger, (Transient Recorder), Program. (Python)

2011-07-31T16:14:48-07:00

Python recipe 577796 by Barry Walker (amiga, analogue, anim, apple, arduino, data, demo, display, e_uae, linux, logger, macbook_pro, program, windows, winuae). Revision 2.

This code is kids level Analogue Data-Logger(/Transient-Recorder), using the Arduino series of dev' boards.

It is no where near completion and is a second feeder/feeler upload only.

It is designed to work from Classic Text Mode Python from Versions 1.4.0 to 2.7.2 on a Classic AMIGA, WinUAE, Linux and Windows, (32 bit), to Vista. Not tested on Python for Windows 7, (32 bit), nor Mac OSX flavours as I don't have these OSes.

Linux versions run from a default root terminal for the time being.

The Arduino dev' board IS catered for in the code for the above platforms just thoroughly read the code for more information. It defaults to a DEMO mode so you can see it working...

The test code for the Arduino Diecimila Dev Board is here:-
