![]() ![]() You can use any method according to your convenience. These are the method to initialize or create an empty list of dictionaries in python. Here you will create an empty list and append the empty dictionary in each iteration in it. You can also use for loop with the dict() function to define the empty dictionaries inside the list. Method 3: Using for loop with dict() function In the same way, you can create 6,7,8 e.t.c unlimited number of dictionaries inside the list by looping a number of times. Let’s say you want five dictionaries inside the list then iterate 5 times and with each iteration create a dictionary inside the list. You will use it for creating an empty list of dictionaries. List comprehension allows writing the loop in a single statement. Output list Method 2: Create an empty list of dictionaries using list comprehension ''' Initialize a dictionary with n key-value pairs.You can check the type of the list of dictionaries using the type() function. We used the following code to generate this graphic: import time Method 5 needed 0.93 seconds for 100 million dict entries. A for loop can be used to iterate through the original dictionary and copy the elements into a new, empty dictionary one by one.Method 4 needed 0.58 seconds for 100 million dict entries.Method 3 needed 0.69 seconds for 100 million dict entries.Method 2 needed 0.67 seconds for 100 million dict entries.In Python 3.6 and earlier, dictionaries are unordered. ![]() As of Python version 3.7, dictionaries are ordered. A dictionary is a collection which is ordered, changeable and do not allow duplicates.
