![]() Image 12 - Iterating through a nested dictionary (2) (image by author) Here’s what you should see on the screen: # Not a dictionary, print the value else: # Combine multiple elements print( f " ") # Access element that contains a dictionary print(employees"]) # Access element that contains a string print(employees"]) Concatenate multiple nested dictionary values.Access a single element which is also a dictionary.Here are a couple of examples of what you can do: You can access elements of a nested dictionary just like you would for a normal one, with one exception - you now need to add an additional set(s) of brackets. How to Access Elements of a Nested Dictionary Up next, let’s see how to access elements of a nested dictionary in Python. Just stick to the first one and you’ll be good to go. In practice, there’s no reason to use this approach to declare nested dictionaries. Image 2 - Nested dictionary of employees (2) (image by author) The resulting data looks the same as what we had before: Here’s the code:Įmployee_emails = ", " "]Įmployees = dict(zip(employee_emails, employee_details)) This will assign appropriate key-value pairs. If you declare your data in this way, you can pass both to zip() and wrap everything inside a call to dict(). employee_details - A list of details for each employee, such as first name, last name, and address.employee_emails - A list of emails that will represent the dictionary keys.It’s used to iterate over two or more iterators at the same time. Using the zip() FunctionĪn alternative way to create a nested dictionary in Python is by using the zip() function. Each of those keys has a dictionary for a value, and there’s even a third dictionary assigned to the address key.ĭictionaries aren’t ordered, so that’s why you’re seeing the data not reflecting the ordering specified in the code. Overall, we have a dictionary with two keys (emails). Image 1 - Nested dictionary of employees (image by author) ![]() Here’s what this nested dictionary looks like: As you can see, the dictionary value is also a dictionary: ![]() Here’s an example - the following code snippet creates a nested dictionary of employees, where employee email is set for the dictionary key, and additional information as a dictionary value. Simply assign it to a variable name, and format the entire thing as JSON. It means you don’t have to use any specific functions or libraries to create a dictionary. The first way to create a nested Python dictionary is by leveraging regular Python notation. There are many ways to create a nested dictionary, but you’ll primarily use two if you’re creating them from scratch in Python. How to Create a Nested Dictionary in Python
