This snippet allows you to get random record from given table by weight. To run it, it must have a field named "weight". The more "weight" is assigned, the more often the record is selected. The value of "weight" should be an integer between 1 and 10 (or anything else).
In this article, the author gives some tips to fetch random record in a multiple records database. He gives two ways to do this job. For this he gives some example function that are very easy to follow and get the exact result. The first way is to...
At the end of this online article the webmasters could gain knowledge about selecting a random record from a set of more records. The author describes five important steps to choose a random record from a recordset. The sample source code given at...
Through this online article the webmasters could learn how to choose a record from a database. The author explains about the task involved in choosing and finally displaying a random record from a database. The author uses appropriate recordset...
The objective of this online article is to teach the webmasters about the method of displaying a random record from a database table. The author explains about how to get a record count, then generating a random number and finally displaying the...
This class can be used to populate a MySQL database with random data. It can scan the list of tables and fields of a MySQL database and generate SQL INSERT statements that will fill the tables with records with random data.
The class...
This is an easy to setup random HTML displayer which can also record the displayed number of each piece of HTML code. /
I've worked on a random user generator in C a long time ago, so I thought I'd make an advanced version of it in Python(3.2). I'll have you know, I am an amateur in Python and even programming for that matter so I'd really appreciate some criticism...
This recipe returns a list of size n such that the contents of the returned list are random 0s and 1s. It returns a random binary list of size n.
This (quick but strangely satisfying) recipe combines the use of random.choice with functools.partial from the standard library. It is a factory function returning random.choice pre-filled with its sequence of options.
This function returns a random element from a sequence. The probability for each element in the sequence to be selected can be weighted by a user-provided callable
Numerical Integration using random sampling.
Generating N random numbers that probability distribution fits to any given function curve.
Calculating PI using random numbers (Monte Carlo method)
3d Surface fitting to N random points. It draws the surface by converting z values to RGB colors.
Returns a random, password-suitable string with the specified number of characters. base64 stores 6 bits in each (8-bit) output character, hence the coefficient.
Implements a complementary-multiply-with-carry psuedo-random-number-generator. Period is 3636507990 * 2 ** 43487 (approximately 10 ** 13101).
This is a class that allows you to set up an arbitrary probability distribution function and generate random numbers that follow that arbitrary distribution.
This function generates random numbers distributed according to the Laplace distribution using the Probability integral transformation
A few days ago I was in need of uniformly random points generation on the surface of sphere. I suddenly discovered that common parametrization with 2 angles is useless, it gathers too many points in the poles. At MathWorld you can find the... |
