Python 2 7 Concatenating Numpy Arrays Vertically And Horizontally
I have a numpy multidimensional array array with the following format a 1 2 8 9 Then I want to add a list with 3 values e g 4 5 6 at the end horizontally and vertically with the following result a 1 2 4 8 9 5 4 5 6
How To Join Two Horizontal Arrays Python Stack Overflow, If you have an array a np array 1 2 3 4 and a second b np array 5 6 7 8 you can do np concatenate a b to give them joined horizontally array 1 2 3 4 5 6 7 8 I think this will do what you want but I will leave it up to you to incorporate this into your main code

np concatenate concatenates along an existing axis whereas np stack concatenates along a new axis For example np concatenate is used to concatenate 2D arrays vertically and horizontally while np stack NumPy Join Arrays With Np concatenate Block Vstack Hstack Etc . To concatenate arrays in numpy you use the numpy concatenate function Here s a simple example import numpy as np array1 np array 1 2 3 array2 np array 4 5 6 result np concatenate array1 array2 print result Output array 1 2 3 4 5 6 In this example we have two arrays array1 and array2 If the axis is one the concatenate funciton will join two arrays horizontally For example For example import numpy as np a np array 1 2 3 4 b np array 5 6 7 8 c np concatenate a b axis 1 print c Code language Python python
