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) |
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) |
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) |
Output:
Before Sorting: ('L1', [87, 34, 56, 12]) ('L2', [23, 0, 30, 10]) ('L3', [1, 6, 2, 9]) ('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]}
