How to insert a text file into a field in PostgreSQL? I'd like to insert a row with fields from a local or remote text file. I'd expect a function like gettext() or geturl() in order to do the following: % INSERT INTO collection(id, path, content) VALUES(1, '/etc/motd', gettext('/etc/motd')); -S. The easiest method would be to use one of the embeddable scripting languages. Here's an example using plpythonu: CREATE FUNCTION gettext(url TEXT) RETURNS TEXT AS $$ import urllib2 try: f = urllib2.urlopen(url) return ''.join(f.readlines()) except Exception: return "" $$ LANGUAGE plpythonu; One

Python open(“x”, “r”) function, how do I know or control which encoding the file is supposed to have?

阅读更多关于 Python open(“x”, “r”) function, how do I know or control which encoding the file is supposed to have?

问题 If a python script uses the open("filename", "r") function to open, and subsequently read, the contents of a text file, how can I tell which encoding this file is supposed to have? Note that since I'm executing this script from my own program, if there is any way to control this through environment variables, then that is good enough for me. This is Python 2.7 by the way. The code in question comes from Mercurial, it can be given a list of files to, say, add to the repository, through a file

Storing Probability table during text compression

阅读更多关于 Storing Probability table during text compression

I am doing a project where I compare different types of Text compression methods such as Huffman and Arithmetic for both static and adaptive form. I make a probability table for both using the number of occurrence of each letter in the text. Now, for adaptive form, the receiver does not need the Probability table but for the static form, we need to transmit this probability table as well to the receiver for decoding the message. Now this storing of the table will need some extra bits, which should be taken into account while comparing. So my question here is: What is the best solution for
