This behavior doesn't match my requirements. Any ideas how can this be solved? Any existing library for this?

  - by Tshepang

  Am surprised there's 3 different forms: RawConfigParser, SafeConfigParser and ConfigParser. I read the differences but why isn't everyone using SafeConfigParser, since it seems, well, safe? I can understand that in the case for Python 2 that the other two were kept for backward compatibility.

• python how to find the median of a list

  - by user3450574

  I'm trying to write a function named median that takes a list as an input and returns the median value of the list. I'm working with Python 2.7.2 The list can be of any size and the numbers are not guaranteed to be in any particular order. If the list contains an even number of elements, the function should return the average of the middle two. This is the code I'm starting with: def median(list): print(median([7,12,3,1,6,9]))
