![]() ![]() The sort() method when invoked on the list of dictionaries with the getVal() function as an input argument for the parameter “ key”, will sort the list as follows. After that, we will pass the getVal() function to the sort() method as an input argument for the parameter key. Here, we have to keep in mind that the key of the key-value pair that is to be used for comparing the dictionaries must be present in all the dictionaries in the list.įor instance, if we have to sort the dictionaries of laptops according to their RAM value, we will first create a function getVal() that takes a dictionary as input and returns the value associated with the key “ RAM” of the dictionary. A dictionary is a collection which is ordered, changeable and do not allow duplicates. Strings are lists of keyboard characters. Dictionaries are used to store data values in key:value pairs. We will choose a specific key-value pair from the dictionaries that will be used as the key for sorting the list of dictionaries. Lists are another data structure, similar to NumPy arrays, but unlike NumPy arrays, lists are a part of core Python. To sort a list of dictionaries in python, we will have to specify the key according to which the dictionaries will be sorted. ![]() How to Sort List of Dictionaries in Python? After finding the dictionary to be updated, we just update the desired key. Method 2: Using keys () After iterating to a list the keys from the dictionary can further be extracted using the keys () function. ![]() In the code, you can observe that we have to perform the search operation to select the dictionary to update. In the output, we have printed the RAM of laptop1 before and after updating it. ![]()
