Sorting a List without Using Import Libraries in Python

Sorting data is a common task in programming, and Python provides several built-in methods to simplify this. However, if you want to sort a list without using any import libraries, you can achieve this with the help of Python's built-in sort() function. In this guide, we’ll address the problem of sorting a complex list of dictionaries and break down an effective solution step-by-step.

The Problem: Sorting a List of Dictionaries

Let’s say you have the following list of dictionaries:

Your goal is to sort this list according to the keys ('1', '2', '3') in ascending order (i.e., 1, 2, 3). The challenge is to perform this sorting without importing any additional libraries—just using Python's built-in functionalities.

The Solution: Using the sort() Method with a Custom Key

In Python, you can use the sort() method, which sorts the list in place. By providing a custom key to the sort() method, you can specify how the list should be ordered.

Step-by-Step Breakdown

Understanding the Data Structure:

Each element in the list is a dictionary, where the keys are strings representing numbers.

We need to convert these string keys to integers in order to sort them correctly.

Using a Custom Key:

The key parameter can be used in the sort() method to determine the sorting criteria.

A lambda function can extract the numeric value from each dictionary's key, allowing us to sort them as numbers rather than strings.

Implementing the Sort:

Here’s how the sorting code looks:

Output:

After executing this code, the sorted output will be:

This shows that the list is now sorted according to the keys in ascending order as intended.

Conclusion

Sorting a list of dictionaries in Python without using import libraries can be accomplished easily with the sort() method and a custom key. By understanding the behavior of the data and effectively using a lambda function as the key, you can achieve the desired order effortlessly.
