If we pass only the array in the sum() function, it’s flattened and the sum of all the elements is returned. import numpy as np array1 = np.array( [[1, 2], [3, 4], [5, 6]]) total = np.sum(array1) print(f'Sum of all the elements is {total}') Output:Sum of all t...
The default, axis=None, will sum all of the elements of the input array. If axis is negative it counts from the last to the first axis. If axis is a tuple of ints, a sum is performed on all of the axes specified in the tuple instead of a single axis or all the axes as before...

Example 1: Sum of All Values in NumPy ArrayThe following code demonstrates how to calculate the sum of all elements in a NumPy array.For this task, we can apply the sum function of the NumPy library as shown below:print(np.sum(my_array)) # Get sum of all array values # 21...
The sum() function is used to calculate the sum of array elements along a specified axis or across all axes. The sum() function is used to calculate the sum of array elements along a specified axis or across all axes. Example import numpy as np array1 =

Axis or axes along which a sum is performed. The default, axis=None, will sum all of the elements of the input array. If axis is negative it counts from the last to the first axis. New in version 1.7.0. If axis is a tuple of ints, a sum is performed on all of the axes spec...
