In this article, we will explore the process of storing values in a dictionary in Python using a for loop. As we know, combining dictionaries with for loops is a potent technique in Python, allowing iteration over keys, values, or both. This discussion delves into the fundamentals of Python dictionaries and provides a demonstration of how to effectively store values within a dictionary using a for loop.

Store Values in Dictionary in Python Using For Loop

Here, are methods for storing values in a Python dictionary using a for loop.

• Using For Loop
• Using Zip Function
• Using Enumerate Function

Store Values in Dictionary in Python Using For Loop

In this example, below Python code below establishes an empty dictionary named my_dict and provides sample data with keys (e.g., ‘name’, ‘age’, ‘city’) and corresponding values (e.g., ‘John’, 25, ‘New York’). Through a for loop, it populates the dictionary by assigning values to their respective keys.

Output :

{'name': 'John', 'age': 25, 'city': 'New York'}

Store Values in Dictionary in Python Using zip Function

In this Python example, the zip function is utilized to pair up the elements from the keys and values lists, and a dictionary named my_dict is created using a concise dictionary comprehension. This approach simplifies the process of combining keys and values, resulting in a dictionary with the specified key-value pairs.

Output :

{'name': 'John', 'age': 25, 'city': 'New York'}

Store Values in Dictionary in Python Using enumerate Function

In this example, below Python code, two lists, `keys` and `values`, are provided. An empty dictionary named `my_dict` is initialized. The for loop, utilizing `enumerate()`, iterates through the keys, pairs them with corresponding values using the index `i`, and populates the dictionary.

Output :

{'name': 'John', 'age': 25, 'city': 'New York'}
