CodingBat List rotate_left3.py

##Given an array of ints length 3, return an array with the elements "rotated left" so {1, 2, 3} yields {2, 3, 1}.
##
##rotate_left3([1, 2, 3]) → [2, 3, 1]
##rotate_left3([5, 11, 9]) → [11, 9, 5]
##rotate_left3([7, 0, 0]) → [0, 0, 7]


def rotate_left3(nums):
  return [nums[1],nums[2],nums[0]]
