flattening list

[Abhishek Mishra]

thanks for the excercise just figured out this -

#!/usr/bin/env python
import sys
sys.setrecursionlimit(2000)

def flatten(l):
  flattened = []
  for i in l:
    if type(i) == type([]):
      flattened += flatten(i)
    else:
      flattened.append(i)
  return flattened




if __name__=='__main__':
  p=[1,[2,3,4],[5,6,],9,[[11,12]]]
  print flatten(p)

But a google search will lead you to more elegant generic solutions :)
