Real Python: Python range(): Represent Numerical Ranges

The range() function in Python generates a sequence of numbers, often used in loops for iteration, and can be used to count backwards by specifying a negative step. By default, it creates numbers starting from 0 up to but not including a specified stop value. The range() function can also be used in various programming scenarios beyond simple loops, making code more efficient and readable. A range in Python is an object representing an interval of integers, often used for looping. The range() function can be used to generate sequences of numbers that can be converted to lists. The range parameters start, stop, and step define where the sequence begins, ends, and the interval between numbers. Ranges can go backward in Python by using a negative step value and can be reversed by using reversed(). A range object can be created by calling range() with one, two, or three arguments, specifying the start, stop, and step values. The range() function is built-in and can be called without any preparations, and it can be used to construct numerical ranges in Python.
