As long as step is one or negative one, it’s straightforward to reverse a range: Python >>> def reverse_range(rng): ... return range( ... rng.stop - rng.step, ... rng.start - rng.step, ... -rng.step, ... ) ... >>> reverse_range(range(5, 0, -1)) range(1,...

2. Python range() with Float (Raises TypeError) The range() function in python is used to generate values within the specified range of integers but not float. It will take only integer values. If we pass the float value, TypeError will be returned. ...
Guido van Rossum (the original creator of the Python language) decided to clean up Python 2.x properly, with less regard for backwards compatibility than is the case for new releases in the 2.x range. The most drastic improvement is the better Unicode support (with all text strings being ...
