What are the built-in types of python?
Python has several built-in data types, including:
range and xrange are used for creating sequences of numbers.range returns a list containing all the numbers in the specified range. It generates the entire list in memory.xrange, on the other hand, returns an xrange object, which is an iterable. It generates numbers on-the-fly as needed, making it more memory-efficient for large ranges.range itself behaves like xrange from Python 2, so there's no xrange in Python 3.
