- Main Differences
- xrange returns an xrange object, while range returns a Python list
- xrange uses yielding technique with generators, while range creates static lists
- xrange is better for large ranges, while range is more memory efficient
- xrange Function
- Available only in Python 2
- Uses start, end, and step parameters
- Default start and step values are 0 and 1
- Can be used with only stop argument
- range Function
- Available in both Python 2 and 3
- Uses start, stop, and step parameters
- Usage Examples
- Both functions support negative numbers
- Range can iterate over same sequence multiple times
- xrange requires explicit list conversion
- Python 3 removed xrange, making range more portable
