Zen of Python

Learning theculture that surrounds a language brings you one step closer to being a betterprogrammer. If you haven’t read the Zen of Python yet open a Python prompt andtype import this. For each of the item on the list you canfind examples herehttp://artifex.org/~hblanks/talks/2011/pep20_by_example.html

Beautifulis better than ugly

Give me a function that takes a list ofnumbers and returns only the even ones, divided by two.

CODE:

  #-----------------------------------------------------------------------
  
  halve_evens_only = lambda nums: map(lambda i: i/2, filter(lambda i: not i%2, nums))
  
  #-----------------------------------------------------------------------
  
  def halve_evens_only(nums):
      return [i/2 for i in nums if not i % 2]
