I want to delete an element from a numpy array by index.

The commands 

arr = np.linspace(-5,5,10)
del arr[0]

The code above throws an error saying cannot delete array elements. Using pop doesn't work either. What should I do?

  • It's not an exact duplicate because this one asks about deleting just one element rather than many. But maybe others can look into it and decide. Commented Jun 5, 2019 at 6:21
  • del and pop are python list operations, and don't apply to ndarray. Commented Jun 5, 2019 at 7:30

You should use np.delete for it.

arr = np.linspace(-5,5,10)
arr = np.delete(arr, 0)
