sorted vs sort python

# The sort() function will modify the list it is called on. 
# The sorted() function will create a new list 
# containing a sorted version of the list it is given.

list = [4,8,2,1]
list.sort()
#--> list = [1,2,4,8] now

list = [4,8,2,1]
new_list = list.sorted()
#--> list = [4,8,2,1], but new_list = [1,2,4,8]

sorted python

var = sorted(old_var)
