Python - Get items in sorted order from given dictionary
The Python dictionary has key and value pairs. In some situation we will need the items of the dictionary to be sorted according to the keys. In this article we'll see the different ways to get a sorted output from the items in the dictionary.
Using Operator Module
The Operator module has itemgetter function which can take 0 as the index of input parameter for the keys of the dictionary. We apply the sorted function on top of itemgetter and get the sorted output.
Example
dict = {12 : 'Mon', 21 : 'Tue', 17: 'Wed'}
import operator
print("\nGiven dictionary", str(dict))
print ("sorted order from given dictionary")
for k, n in sorted(dict.items(),key = operator.itemgetter(0),reverse = False):
print(k, " ", n)Output
Running the above code gives us the following result −
Given dictionary {12: 'Mon', 21: 'Tue', 17: 'Wed'}
sorted order from given dictionary
12 Mon
17 Wed
21 TueUsing the Sorted Method
The sorted method can be directly applied on a dictionary which sorts the keys of the dictionary.
Example
dict = {12 : 'Mon', 21 : 'Tue', 17: 'Wed'}
#Using sorted()
print ("Given dictionary", str(dict))
print ("sorted order from given dictionary")
for k in sorted(dict):
print (dict[k])Output
Running the above code gives us the following result −
Given dictionary {12: 'Mon', 21: 'Tue', 17: 'Wed'}
sorted order from given dictionary
Mon
Wed
TueUsing dict.items()
We can also apply the sorted method to dict.items. In this case both the keys and values can get printed.
Example
dict = {12 : 'Mon', 21 : 'Tue', 17: 'Wed'}
#Using d.items()
print("\nGiven dictionary", str(dict))
print ("sorted order from given dictionary")
for k, i in sorted(dict.items()):
print(k,i)Output
Running the above code gives us the following result −
Given dictionary {12: 'Mon', 21: 'Tue', 17: 'Wed'}
sorted order from given dictionary
12 Mon
17 Wed
21 Tue
