Splitting array into multiple ones

Question

I'd like to split my array into multiple ones: The original array looks as follows:

array([[228.6311346 , 228.6311346 , 228.6311346 ],
 [418.57914851, 0. , 228.321311 ],
 [416.83133465, 0. , 723.25171282]])

The resulting arrays should look like this:

array1([228.6311346, 418.57914851, 416.83133465])
array2([228.6311346, 0., 0.])
array3([228.6311346, 228.321311, 723.25171282])

• NewtonL: Hmm would you like them to be printed or to be assigned to a variable?
• Chris: numpy.org/doc/stable/reference/generated/numpy.hsplit.html np.hsplit(x,3)
• Tim Roberts: These are numpy arrays? You can use array1 = array[0,:] and array2 = array[1,:], etc.
• mkrieger1: Does this answer your question? How to access the ith column of a NumPy multidimensional array?
• Marco: @Chris exactly what I was looking for, thank you!

Answer 1

for i in range(len(array)):
 exec("array"+str(i+1)+"=array["+str(i)+"]")

It will create your variable dynamically and assign the corresponding value to it.

array = [[1],[2],[3]]
print(array0) // outputs [1] after running above code

You can also use numpy.hsplit Doc Here

numpy.hsplit(ary, indices_or_sections)
# Split an array into multiple sub-arrays of equal size.

• 0x5453: split/hsplit is the correct answer. exec is a bad idea (despite the fact that it more closely matches OP's desired output).
