Converting user input into nested list in Python

Title: Converting User Input into Nested List in Python
Introduction:
In Python, converting user input into a nested list can be a common requirement, especially when dealing with hierarchical data or structured information. This tutorial will guide you through the process of taking user input and transforming it into a nested list using Python.
Step 1: Accepting User Input
Let's start by accepting user input. In this example, we'll take input for a simple nested list representing a matrix. Users will input rows of space-separated numbers, and each row will be separated by a newline.
Step 2: Converting User Input into Nested List
Now, we will write a function to process the user input and convert it into a nested list. We'll use list comprehensions to achieve this.
This function uses split('\n') to separate rows and split() within each row to extract individual elements. The map(int, ...) is used to convert the string numbers into integers.
Step 3: Putting it All Together
Now, let's combine the functions and provide a complete example:
This program prompts the user to enter matrix rows, processes the input, and prints the resulting nested list.
Example Usage:
Output:
Conclusion:
Converting user input into a nested list in Python is a straightforward process. By using list comprehensions and appropriate splitting techniques, you can efficiently handle various input scenarios and create nested lists based on user-provided data.
