dealing with list of dictionaries python

The zip_longest is a built-in function that comes under the itertools module. Here is the result of the above Python program. And then we used the dict() and zip() functions to create a dictionary of lists in Python. In the above example, we have taken 2 lists- keys and values. And then, we will use the dict() constructor to convert that tuple to the dictionary. So, in this method, we will use the zip() function to aggregate multiple list data into a tuple. On the other side, zip() is another built-in Python function that allows aggregate elements from multiple lists to a tuple. The dict() constructor is another way to define a dictionary in Python. Read: Python dictionary multiple keys Method 2: Using dict() and zip() In the above example, we used the dictionary literals to define a dictionary of lists named students_marks.Īfter this, we use the for loop to iterate over each key and its list of values and calculate the average marks for each student. Print('Average marks of', name, 'is', avg) # Calculating the average of each student

# Defining a dictionary of list using dict literals Here is an example of defining a dictionary of lists using dictionary literals. Within the curly brackets, we use a colon to separate key-value pairs separated by coma. In Python, we can define dictionary literals by using curly brackets. One of the primary ways to create a Python dictionary of lists is by using the dictionary literals. Let us discuss each method to create a Python dictionary of lists. However, to obtain the values of a dictionary, we use the key name within the square brackets.

First, we insert key-value within the curly brackets to create a dictionary of lists. In Python, the dictionary of lists means having a dictionary consisting of values as a list.īasically, a Python dictionary is an unordered and immutable data type and can be used as a key element. Method 3: Using a dictionary comprehension.
