How to Create Multiple Variables from a List of Strings in Python?

Creating Multiple Variables from a List of Strings in Python

In Python, you may encounter situations where you need to create multiple variables from a list of strings. For instance, consider you have a list:

names = ['apple', 'orange', 'banana']

Your goal is to create separate lists for each element, named after the corresponding string:

apple = []
orange = []
banana = []

Solution

To achieve this, you can employ a dictionary:

fruits = {k: [] for k in names}

This creates a dictionary where keys are strings from the 'names' list, and values are empty lists.

Usage

To access each list, you can use the dictionary key:

fruits['apple']  # Returns an empty list for 'apple'
fruits['orange'] # Returns an empty list for 'orange'
fruits['banana'] # Returns an empty list for 'banana'

Benefits of Using a Dictionary

While creating separate variables for each element may seem logical, using a dictionary offers several benefits:

• Ease of Access: Dictionaries allow you to access values using keys, simplifying code readability and maintenance.
• Flexibility: You can dynamically add or remove elements from the dictionary as needed.
• Data Integrity: Variables created using this method always refer to the same list, ensuring consistent data.
