I'm hoping to combine two arrays
A: ([1,2,5,8])
B: ([4,6,7,9])
to
C: ([[1,4],
[2,6],
[5,7],
[8,9]])
I have tried insert, append and concatenate, they only lump all elements together without giving the dimension in C.
I'm new to Python, any help will be appreciated.
Use numpy.column_stack:
Stack 1-D arrays as columns into a 2-D array
np.column_stack((A, B))
array([[1, 4],
[2, 6],
[5, 7],
[8, 9]])
arr[:, 0], and for the second column, use arr[:, 1]1, you would use the first row, first column, so arr[0, 0]According to your initial approach, you only need to use zip, which returns an iterator of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables.
import numpy
A = numpy.array([1,2,5,8])
B = numpy.array([4,6,7,9])
print(list(zip(A, B)))
It will print:
[(1, 4), (2, 6), (5, 7), (8, 9)]
print(list(map(list, zip(A,B))))?
