How to Replace Pipe Symbols with New Lines in Python Using the re Module

Managing text data efficiently is a common challenge programmers often face. One such scenario that may arise is when you need to format a string embedded within specific delimiters and replace certain characters with new lines. For instance, you might have text containing information separated by pipe (|) symbols and want to split that into separate lines instead. In this post, we’ll walk through how to replace pipe symbols with new lines in Python using the re module.

The Problem

Let’s say you have a string that looks like this:

Your goal is to extract the text between the <BusContact> tags, and format it so that the text appears on two separate lines instead of a single line separated by a pipe character. The expected output would be:

This means we need to replace the | character with a newline character (\n). Let’s dive into how we can achieve this using Python.

The Solution

Step 1: Write the Initial Code

First, you need to extract the text between the <BusContact> tags using a regular expression. Here’s how this initial part looks:

Conclusion

In summary, replacing characters in a string using Python, especially within tags, can be done efficiently with the re module and string manipulation methods. Remember to extract the details first and then perform the necessary replacements to format your output as required. This approach not only simplifies your code but keeps it clean and readable. Happy coding!
