Python | Sort the list alphabetically in a dictionary
In Python Dictionary is quite a useful data structure, which is usually used to hash a particular key with value, so that they can be retrieved efficiently.
Let’s see how to sort the list alphabetically in a dictionary.
Example #1:
# Python program to sort the list # alphabetically in a dictionary dict ={ "L1":[87, 34, 56, 12], "L2":[23, 00, 30, 10], "L3":[1, 6, 2, 9], "L4":[40, 34, 21, 67] } print("\nBefore Sorting: ") for x in dict.items(): print(x) print("\nAfter Sorting: ") for i, j in dict.items(): sorted_dict ={i:sorted(j)} print(sorted_dict) |

filter_none
Output:
Before Sorting:
('L2', [23, 0, 30, 10])
('L3', [1, 6, 2, 9])
('L4', [40, 34, 21, 67])
('L1', [87, 34, 56, 12])
After Sorting:
{'L2': [0, 10, 23, 30]}
{'L3': [1, 2, 6, 9]}
{'L4': [21, 34, 40, 67]}
{'L1': [12, 34, 56, 87]}
Example #2:
# Python program to sort the list # alphabetically in a dictionary dict ={ "L1":["Geeks", "for", "Geeks"], "L2":["A", "computer", "science"], "L3":["portal", "for", "geeks"], } print("\nBefore Sorting: ") for x in dict.items(): print(x) print("\nAfter Sorting: ") for i, j in dict.items(): sorted_dict ={i:sorted(j)} print(sorted_dict) |
chevron_right
filter_none
Output:
Before Sorting:
('L3', ['portal', 'for', 'geeks'])
('L1', ['Geeks', 'for', 'Geeks'])
('L2', ['A', 'computer', 'science'])
After Sorting:
{'L3': ['for', 'geeks', 'portal']}
{'L1': ['Geeks', 'Geeks', 'for']}
{'L2': ['A', 'computer', 'science']}
Example #3:
# Python program to sort the list # alphabetically in a dictionary dict={ "L1":[87,34,56,12], "L2":[23,00,30,10], "L3":[1,6,2,9], "L4":[40,34,21,67] } print("\nBefore Sorting: ") for x in dict.items(): print(x) sorted_dict = {i: sorted(j) for i, j in dict.items()} print("\nAfter Sorting: ", sorted_dict) |

('L2', [23, 0, 30, 10])

('L4', [40, 34, 21, 67])
After Sorting: {'L1': [12, 34, 56, 87],
'L2': [0, 10, 23, 30],
'L3': [1, 2, 6, 9],
'L4': [21, 34, 40, 67]}
