• Extracting a given number of the highest values in a List

  - by James P.

  I'm seeking to display a fixed number of items on a web page according to their respective weight (represented by an Integer). The List where these items are found can be of virtually any size.

Is there a more elegant solution though that could be used to prepare, say, the top eight items?

• converting factored number to decimal in MS SQL

  - by LS

  I need to convert a number which gives decimals in factored format in to decimals, i.e. 11.16 is 11.5 in decimal. This is because 16 is in base of 32 and 11.16 should be read as 11+16/32 = 11.5 I get 11.16 as a string and I need to change it to 11.5 as numeric in MS SQL(2005) database. Any shorter way of doing this rather than splitting strings,converting to numerics,maths,convert to string, concatenate and then convert to numeric?

• Go through a number of functions in Python

  - by Asaf

  I have an unknown number of functions in my python script (well, it is known, but not constant) that start with site_... I was wondering if there's a way to go through all of these functions in some main function that calls for them. something like: foreach function_that_has_site_ as coolfunc if coolfunc(blabla,yada) == true: return coolfunc(blabla,yada) so it would go through them all until it gets something that's true. thanks!
