And also explained using an index how we can access the corresponding key or value of the dictionary. Finally, we print ‘sorteddict‘ using the ‘print()‘ function. We then use the ‘dict()‘ function to convert the sorted list of tuples back to a dictionary, and assign it to ‘sorteddict‘. Python - Convert Dictionaries List to Order Key Nested dictionaries 3. The result of ‘sorted()‘ is a list of tuples, where each tuple contains a key-value pair from the dictionary, sorted by value. See the following article for more information. 4 Answers Sorted by: 69 Here is one way to do this: > sorted (ems (), keylambda e: e 1 2) ('item2', 8, 2, 3), ('item1', 7, 1, 9), ('item3', 9, 3, 11) The key argument of the sorted function lets you derive a sorting key for each element of the list. By specifying a function to be applied to each element of the list, it is sorted according to the result of that function. In this article, I have explained how to get the index position of a specified key in a dictionary using different ways with examples. Sort List by Dictionary values using emgetter () with sorted () This method uses the itemgetter () function from the operator module along with the sorted () function to sort the list based on the values of the dictionary. Ways to sort list of dictionaries by values in Python Using itemgetter 2. To sort a list of dictionaries according to the value of the specific key, specify the key parameter of the sort () method or the sorted () function. ![]() Pass the specified key into the index () function, it will check the passed key is exist in the list and return the index position of the passed key. Sort List of Dictionaries in Python (2 Examples) In this post you’ll learn how to sort a list of dictionaries in the Python programming language. Let’s understand this by taking an example. In this article, we will discuss how we can create a list of dictionaries in python. It is the unordered collection of the data and allows storing duplicate values, but the key must be unique. It is mutable in nature, which means we can change data after its creation. Lists are used to store atomic objects while dictionaries store key-value pairs. How to sort a dictionary in Python Python dictionary is the collection of data which stored in the key-value form. ![]() ![]() In this article, we’ll learn how to sort them in a custom order. How to Sort List of Dictionaries in Python Conclusion We use both lists and dictionaries in our python programs. Then use the list.index () function to get the index position of the specified key in the dictionary. Sorting list of dictionaries by custom order in Python In the previous articles, we have discussed several ways of sorting dictionaries and lists of dictionaries. ![]() Suppose you want to sort the following list of dictionaries with primary key 'name' ascending, and secondary key 'surname' descending.# Below are the examples of getting the index of specified Key First, using list () function you can convert the dictionary to a list of keys. to sort the list of dictionaries by key age, name (like in SQL statement ORDER BY age, name), you can use: newlist sorted( listtobesorted, keylambda k: (kage, kname) ) or, likewise. the keys support comparison but not negation. To supplement rather than repeat what is stated in the other answers, this question raises an interesting point (although not directly needed in the case in the question) about what happens if you want to sort on two keys, with the primary ascending and the secondary descending, but where neither key is numeric so you cannot employ the trick of negating one of the keys - i.e.
