How to Color a Specific Word in a Docx File with Python

When working with documents in Python using the python-docx library, it’s common for developers to want to style text in a variety of ways—one of which is applying colors to specific words. If you're trying to change the color of just a select few words within a sentence, you might find that most example codes apply colors to entire sentences, leaving you puzzled about how to achieve your desired effect.

In this post, we will guide you through step-by-step instructions on how to apply different colors to specific words while keeping the rest of the text in its standard format.

Understanding the Problem

The issue arises when you want to highlight particular words in a sentence without affecting the other text. For example, if you have the sentence:

"I want a color for a particular word in this sentence not to this whole sentence"

You may wish to color just the words "want," "particular," and "this." The challenge lies in how to apply a color only to those specific words.

The Solution

To accomplish this, you need to split your sentence into words and iterate through them individually. For each word, you can check if it belongs to your list of selected words. If it does, you apply the desired color; if not, you simply add the word without any special formatting.

Step-by-Step Instructions

Here’s a clear breakdown of how to implement this solution:

Import Required Libraries:
You need to import the necessary components from the docx library.

Apply Coloring Logic:

Check if the current word is in the selected_words list.

If yes, create a new run with that word and apply the desired color.

If no, simply add the word normally.

Add a space after each word so that they appear correctly in the sentence.

Conclusion

With just a few lines of code, you can customize your Word documents to highlight specific words with unique colors. This method allows for greater flexibility and creativity when presenting text in Python-generated documents.

Now you can easily make your important words stand out, enhancing the overall presentation of your document!
