A set of **arrays** is called "broadcastable" to the same **NumPy** shape if the following rules produce a valid result, meaning one of the following is true: The **arrays** all have exactly the same shape. The **arrays** all have the same number of dimensions, and the length of each dimension is either a common length or 1.. The most basic way to create datetimes is from strings in ISO 8601 date or. np.zeros(shape=(3, 15), dtype=int) As you can see how simple it is to create **array** with zeros() function. Finally, lets take a look at the syntax of **numpy** zeros() function. np.zeros(shape, dtype=None) OR **numpy**.zeros(shape, dtype=None) shape parameter is used to specify the dimensions of the **Numpy** **array**. Here, you specify the value in the form.
