Python’s TextWrapper: A Guide to Indenting Wrapped Text


Could you advise on the method for implementing indentation in text that has been wrapped using the TextWrapper module?


Indenting Wrapped Text with Python’s TextWrapper Module

When working with text in Python, particularly in creating console applications or formatting output, you might encounter situations where you need to wrap text to a certain width. The `TextWrapper` module in Python’s standard library is a powerful tool for this purpose. But what if you want to add indentation to your wrapped text for better readability or formatting purposes? Let’s explore how you can achieve this with the `TextWrapper` module.

Understanding TextWrapper

Firstly, it’s important to understand what the `TextWrapper` module does. It provides a convenient way to wrap text into lines of a specified width. When text is wrapped, it is split into lines so that it fits within a given width constraint, ensuring that the text doesn’t spill over the desired column in your output.

Implementing Indentation

To implement indentation, you can use the `initial_indent` and `subsequent_indent` attributes of the `TextWrapper` class. Here’s a step-by-step guide:

1. Import the TextWrapper Class

Begin by importing the `TextWrapper` class from the `textwrap` module: “`python from textwrap import TextWrapper “`

2. Create a TextWrapper Instance

Instantiate the `TextWrapper` class with your desired width: “`python wrapper = TextWrapper(width=50) “`

3. Set Indentation

Use the `initial_indent` attribute to set the string that will be placed at the beginning of the first line of wrapped text. Use `subsequent_indent` for all the following lines: “`python

Four spaces for example

wrapper.subsequent_indent = ‘ ‘ “`

4. Wrap Your Text

Now, you can wrap your text using the `wrap` method, which returns a list of output lines, or the `fill` method, which returns a single string: “`python text = “This is an example paragraph that will be wrapped and indented using the TextWrapper module in Python.” wrapped_text = wrapper.fill(text) print(wrapped_text) “` Result

The output will be a nicely formatted block of text with each line indented as specified. This method is particularly useful for creating text-based user interfaces or formatting long blocks of text in a readable way.


Indenting wrapped text in Python is straightforward with the `TextWrapper` module. By setting the `initial_indent` and `subsequent_indent` attributes, you can control the indentation of the first and subsequent lines, respectively. This allows for flexible and visually appealing text formatting in your Python applications.

I hope this article provides a clear understanding of how to use indentation with the `TextWrapper` module in Python. If you have any further questions or need more examples, feel free to ask!
