The doc of reversed() says seq parameter as shown below:

reversed(seq)
Return a reverse iterator. seq must be an object which has a reversed() method or supports the sequence protocol (the len() method and the getitem() method with integer arguments starting at 0).

But the docstring of reversed() says sequence parameter as shown below:

print(help(reversed))
# class reversed(object)
#  |  reversed(sequence, /)
#  |
#  |  Return a reverse iterator over the values of the given sequence.

So, the parameter name should be the same to avoid confusion.
