python column split
numpy, python
Solution
I think NumPy is good for this:
>>> import numpy as np
>>> my_list = [[1,2,3],[4,5,6],[7,8,9]]
>>> x = np.array(my_list)
>>> np.transpose(x).tolist()
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
Problem
I have a python array in the format: ``` [[1,2,3],[4,5,6],[7,8,9]] ``` Is there a way for me to break it up into columns to give: ``` [[1,4,7],[2,5,8],[3,6,9]] ```
