In this example, I’ll show how to calculate the standard deviation of all values in a NumPy array in Python.For this task, we can apply the std function of the NumPy package as shown below:print(np.std(my_array
my_array=np.array([[1,2,7,2,3],# Create example array[7,1,1,5,6],[5,2,5,5,8]])print(my_array)# Print example array# [[1 2 7 2 3]# [7 1 1 5 6]# [5 2 5 5 8]] The previous output of the Python console shows the structure of our example data – We have crea...
def bubble_sort(arr): n = len(arr) for i in range(n): for j in range(0, n-i-1): if arr[j] > arr[j+1]: arr[j], arr[j+1] = arr[j+1], arr[j] return arr example = [64, 34, 25, 12, 22, 11, 90] sorted_example = bubble_sort(example) print("Sorted array is...
Problem Definition In this example we want to translate a string representing order of magnitude into a corresponding numerical value using array/table lookup. This example will be explained by means ...

You can store the current value of array of strings into another array tag. You can use the below calculation/script, in this example, the CurrentValue function returns the result as a python list that will be stored into the appropriate historian array type: ...
