in lesson “Python Lists and Dictionaries”, part " 9 more with ‘for’ " in the partition “Learn” it said this (" 2. Then, we sort animals into alphabetical order. Note that .sort() modifies the list rather than returning a new list.")
my question is which is the difference between the list changes and the creation of a new list, which program is made when I type the code "> animals.sort() "
thank you very much
