Python Program to Find Smallest Number in an Array

                # Update the smallest if the current element is smaller
                if num < smallest:
                    smallest = num

            # Return the smallest element
            return smallest

        # Initialize an empty array to store user input

            # Check if the user wants to stop entering elements
            if user_input.lower() == 'done':
                break

            # Convert the input to an integer and add it to the array

                print("Invalid input. Please enter a valid integer or 'done' to finish.")

        # Call the function with the user input array and print the result
        result = find_smallest(user_array)

        Enter an element (or 'done' to finish): 4
        Enter an element (or 'done' to finish): 10
        Enter an element (or 'done' to finish): 43
        Enter an element (or 'done' to finish): 8
        Enter an element (or 'done' to finish): 34
        Enter an element (or 'done' to finish): done
        The smallest element in the array [4, 10, 43, 8, 34] is: 4
