This example for variable value swapping introduces three new concepts:
1. the tuple data type
2. special tuple syntax, omitting parentheses
3. container unpacking in an assignment
I think using a list is much clearer, and only introduces the concept of
container unpacking.
right, left = [left, right]

Thanks, I agree that using a list is more clear (I think these were remnants from the old lessons which introduced tuples). |
