I have an array which shape is (100,784), float type.

And I want to change the index of columns randomly.

Many have suggested the random function, but I want to change the index of the row without changing the index of the column at all. Please help. thank you.

Use the random library, `random.shuffle(list)` – Philip Rollins Apr 09 '20 at 12:50

Are you trying to just shuffle the array within the 2d arrays – Simon J Apr 09 '20 at 13:54
yes. and only for row index. – Insung Lee Apr 09 '20 at 13:57
