python: combine 2 ordered lists into list of tuples

Question

I have 2 lists that I want to combine into a single list of tuples, so that order is maintained and the result[i] is (first[i], second[i]). Assume

Answer 1

>>> first = [1,2,3]
>>> second = [4,5,6]
>>> list =zip(first,second)
>>> list
[(1, 4), (2, 5), (3, 6)]

or also for lists instead of tuple, using numpy

>>> lista = [first,second]
>>> import numpy as np
>>> np.array(lista)
array([[1, 2, 3],
       [4, 5, 6]])
>>> np.array(lista)[:,0]
array([1, 4])
>>> np.array(lista)[:,1]
array([2, 5])
>>> np.array(lista)[:,2]
array([3, 6])
