sorted a python list by value which has values code example

Example 1: how to sort a dictionary by value in python

import operator
x = {1: 2, 3: 4, 4: 3, 2: 1, 0: 0}
sorted_x = sorted(x.items(), key=operator.itemgetter(1))


# Sort by key
import operator
x = {1: 2, 3: 4, 4: 3, 2: 1, 0: 0}
sorted_x = sorted(x.items(), key=operator.itemgetter(0))

Example 2: 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]
