In Python, a list is a collection of arbitrary objects, somewhat akin to an array in many other programming languages but more flexible. To define a list, you typically enclose a comma-separated sequence of objects in square brackets ([]), as shown below:...

While Python doesn’t directly support the required data type, you can use the array module to declare an array of signed short numbers and pass your bytes object as input. In this case, you want to use the lowercase letter "h" as the array’s type code to tell Python how to interpre...
