Write multiple NumPy arrays into CSV file in separate columns?
csv, numpy, python
Solution
I think this should do what you want:
output = np.column_stack((arrA.flatten(),arrB.flatten(),arrC.flatten()))
np.savetxt('output.dat',output,delimiter=',')
Problem
How to write multiple numpy arrays into one csv file in multiple columns？ ``` import numpy import csv arrA = numpy.array(file.root.a) arrB = numpy.array(file.root.b) arrC = numpy.array(file.root.c) for i in range (480): for j in range (640): (write arrA[i,j] into column1,write arrB[i,j] into column2,write arrC[i,j] into column3) ``` Thanks a lot!
