Combine specific value of Multiple Arrays into one Single Array-CodePudding

Say for example I have these 3 arrays:

# Array 1:
array_1 = [[100, 0, 0, 0, 0, 100],
           [0, 100, 0, 0, 0, 100],
           [0, 0, 100, 100, 0, 0]]

# Array 2:
array_2 = [[0, 0, 0, 0, 100, 0],
           [0, 0, 0, 0, 0, 0],
           [0, 0, 0, 0, 0, 100]]

# Array 3:
array_3 = [[0, 0, 0, 0, 0, 0],
           [0, 0, 0, 0, 100, 0],
           [0, 0, 0, 0, 0, 0]]

How will I be able to combine the 3 arrays into a one single array?

This will be the expected output:

[[100 0 0 0 100 100]
[0 100 0 0 100 100]
[0 0 100 100 0 100]]

As you can see, the 100s from array_1, array_2 and array_3 can be seen in the newly created array.

Combination of 100s must be with the same row as the other.

CodePudding user response：

In this case, you can just add the arrays together

>>> a = np.arange(18).reshape((3,6))
>>> b = np.arange(18).reshape((3,6))
>>> c = np.arange(18).reshape((3,6))
>>> a
array([[ 0,  1,  2,  3,  4,  5],
       [ 6,  7,  8,  9, 10, 11],
       [12, 13, 14, 15, 16, 17]])
>>> a   b   c
array([[ 0,  3,  6,  9, 12, 15],
       [18, 21, 24, 27, 30, 33],
       [36, 39, 42, 45, 48, 51]])
