Learn how to insert new axes into a NumPy array using the np.expand_dims() function. Enhance your data manipulation skills with this useful technique.
The numpy.insert() function is used to insert values along the given axis before the given indices.The function can be used to insert a single value or multiple values into an existing array. The function also provides the option to insert values at specific locations within the array....
The following example demonstrates how to add elements to a NumPy array using thenumpy.append()function: importnumpyasnp# create 2D array objects (integers)np_arr1=np.array([[1,2],[3,4]])np_arr2=np.array(
