For mathematical problems, NumPy Array is more efficient. Unlike arrays, a single list can store elements of any data type and does everything an array does. We can store an integer, a float and a string inside the same list. So, it is more flexible to work with. [10, 20, 30, 40, 50 ] is an example of what an array would look like in Python, but
