Parsing Multi-line Text Blocks in YAML with PyYAML - Indentation Issues
I've searched everywhere and can't find a clear answer. I'm working on a project where I need to parse a YAML configuration file that includes multi-line text blocks, but I'm running into issues with indentation and parsing errors. The YAML structure looks something like this: ```yaml version: 1.0 services: web: description: | This service handles all web requests. It is designed to be resilient and scalable. ports: - "80:80" database: description: | Persistent storage for application data. ports: - "5432:5432" ``` When I try to load this using PyYAML (version 5.4), I use the following code: ```python import yaml with open('config.yaml', 'r') as file: config = yaml.safe_load(file) print(config) ``` However, I receive the behavior `YAMLError: mapping values are not allowed here`. I suspect this is due to the way multi-line strings are formatted in YAML, particularly with indentation. I've tried various combinations of spaces and line breaks, but nothing seems to work. I've also validated the YAML file with online validators and they all show it as valid. How should I format the YAML file so that PyYAML can correctly parse the multi-line descriptions without throwing an behavior? Is there a best practice for handling multi-line strings in YAML that I might be missing? Any insights would be appreciated! For context: I'm using Python on Ubuntu. Is there a better approach? I'm working on a API that needs to handle this. Any ideas what could be causing this?
