I was going through this topic of swapping rows in a NumPy array and came across this code:
Although this method is easy enough, sometimes it would be difficult if I want to swap many rows. Is there any dedicated functionality regarding this? Please let me know.
One efficient method for swapping rows in a 2D NumPy array is to use the slicing method. This method can quickly swap rows of the same length, and you can even swap any number of rows in a single line of code. Here is an example code that demonstrates how to swap the first and third rows of a 2D NumPy array:
Note that this technique also utilizes the
copy() method to avoid referencing the original rows. I hope this explanation helps!
