range(start,end,step)

• start: start counting from the beginning. The default is zero.
  For example: range (5) is equivalent to the range (0,5)

  For example list (range (9,5)) is [0,1,2,3,4], no 5.
• end: step size, default is 1.
  For example: range (0,5) is equivalent to the range (0,5,1)

>>> list(range(10))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

>>> list(range(1,10))
[1, 2, 3, 4, 5, 6, 7, 8, 9]

>>> list(range(1,10,4))
[1, 5, 9]

>>> list(range(10,-1,-1))
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
