1. Sum of All the Elements in the Array 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 ...
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...
Thesum()function returns the sum of array elements Example 1: sum() With 2-D Array Theaxisargument defines how we can find the sum of elements in a 2-D array. Ifaxis=None, the array is flattened and the sum of the flattened array is returned. Ifaxis=0, the sum is calculated colum...

but depending on the programming language, can also include other data types as long as there's a clear definition of what addition means for those types. In higher-level programming languages like Python, the sum function simplifies the task of adding elements, making it a seamless operation....
