![]() ![]() ![]() Sorted(l, key=lambda x: x) = sorted(l, key=emgetter('name'))īoth techniques sort the list in the same order (verified by execution of the final statement in the code block), but the first one is a little faster. # Check that each technique produces the same sort order %timeit sorted(l, key=emgetter('name'))ġ0.7 µs ± 38.1 ns per loop (mean ± std. Note that since score is a string value, it needs to be converted to float for comparison. However, be aware that this sort method is case sensitive. # Test the performance with itemgetter sorting on name 4 Answers Sorted by: 11 You can sort by a tuple: sorted (l, keylambda k: (float (k 'score'), k 'id'), reverseTrue) This will sort by score descending, then id descending. csvmappinglist):minindex):csvmappinglistminindex'Age'csvmappinglist'Age':minindex,csvmappinglistminindexcsvmappinglistminindex,csvmappinglisti 'Favorite Color' In both cases, the list will be sorted alphabetically as the values are strings. %timeit sorted(l, key=lambda x: x)ġ3 µs ± 388 ns per loop (mean ± std. # Test the performance with a lambda function sorting on name 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. ![]() Please tell me about it in the comments if you have further questions.Using the Pandas package is another method, though its runtime at large scale is much slower than the more traditional methods proposed by others: import pandas as pd In this Python programming tutorial, you have learned how to create a sorted list of dictionaries in Python. In this article, we will discuss how we can create a list of dictionaries in python. See the following article for more information. By specifying a function to be applied to each element of the list, it is sorted according to the result of that function. Lists are used to store atomic objects while dictionaries store key-value pairs. 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.
