METHODS IN DICTIONARY | DICTIONARY METHODS - PYTHON PROGRAMMING

Update is used to add one or more items in the existing dictionary

Can you explain why a.sort() returns None for a list a, but a.values() doesn't return None if a is a dictionary. Both dictionaries and lists are mutable (and if mutable, are modified in place, right?). So why is a method such as sort on a list void whereas a method on a dictionary not void (and can be assigned to another variable, printed etc). Any help would be great because right now I have no clear appreciation between mutability, modifying in place and returning None . Thanks

Thank you very much sir🙏🙏🙏🙏
