Beauty Leads to Happiness
Happiness Leads to productivity
….. So,
Beauty leads to Productivity
You can recognize truth by its beauty and simplicity. When you get it right, it is obvious that it is right.
- Richard Feynman
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away
-Antoine de Saint-Exupery

LESS IS MORE (BEAUTIFUL)
l = [ 3, 7, 8, 6, 5, 11 ]
q = []
for i in range( len(l) ):

LESS IS MORE (BEAUTIFUL)

LESS IS MORE (BEAUTIFUL)

q = [ x * 2 for x in l ]
# Double only odd numbers? …
LESS IS MORE (BEAUTIFUL)
q = [ x * 2 for x in l if not (x % 2) ]
VS
q = map( lambda x : x * 2, filter(lambda y : y % 2 != 0, l ) )
ATTITUDE IS NO SUBSTITUTE FOR COMPETENCE
O(n) = log n
VS
O(n) = n log n
KNOWING IS EVERYTHING
Insertion Sort (n^2) vs Merge Sort (n log(n))
