How to Split a Document into a List in Python

When working with large texts in Python, you may find yourself needing to break a document into multiple parts for easier handling. This is especially useful when you're dealing with large paragraphs or sections that you'd like to process individually. One common operation is splitting text by new line characters. In this guide, we will guide you through the steps needed to achieve this in Python.

Understanding the Problem

Suppose you have a long document encapsulated within a list. It may look something like this:

The goal is to split this long text into manageable pieces (list items) based on new line \n characters.

Solution Steps

Step 1: Split the List Using New Line Notation

To get started, we will utilize Python’s string methods. Here’s the core function we’ll use:

Here, ls[0] accesses the first item in the list, which is your long string. The split('\n') function then breaks the string at every occurrence of the new line character.

Step 2: Removing Empty Entries

After splitting, you might end up with some empty strings, especially if there are multiple new line characters together. We can use a simple for loop to filter these out. The code will look like this:

This loop will iterate through each item in the result list res, and only print items that have a length greater than zero.

Full Code Example

Bringing it all together, here’s the complete Python code that will perform the entire operation:

Conclusion

Splitting a document into a list based on new line characters in Python is a straightforward task with the right method. Armed with the steps outlined in this blog, you can conveniently break down and manipulate long texts, improve readability, and make further processing tasks much more manageable.

Now you have the skills to take on text processing in Python efficiently! Happy coding!
