Question

Have:

keys = ['a', 'b','c','d']

numpy array….

array = numpy.array([[1, 2, 3, 5], [6, 7, 8, 10], [11, 12, 13, 15]])

want

my_dict = {'a': [1,6,11], 'b': [2,7,12], 'c': [3,7,13], 'd': [5,10,15]}

Answer 1

Transpose the array, zip() the keys with the result and convert to a dict:

dict(zip(keys, zip(*array)))

Since array is a NumPy array, you can also use

dict(zip(keys, array.T)))
