Most programming languages require the type of data storage associated with an integer value to be declared before the variable can be used. Python 2 has two integer types: int, which is a signed integer whose size equals your machine's word size (but is always at least 32 bits), and long, which is unlimited in size. By convention our module is imported into the shorter and more pythonic "sitk" local name. It then calls the FromBase64String (String) method to decode the UUencoded string, and calls the BitConverter.ToInt32 method to convert each set of four bytes (the size of a 32-bit integer) to an integer.

A default integer data size (usually, but not always, 32-bits) is assumed if none is explicitly declared. Making statements based on opinion; back them up with references or personal experience. Or, not long. Early processors only fetched/stored 8 bits at a time, so performing an operation on a 32-bit data type would take twice as long as with a 16-bit data type. 3) Count 32 starting from the RIGHT and copy it.
