[Python] Best practice for storing multiline prompt templates with placeholders in python?...

I need to store multiline prompt templates in my python project, and want to:

• replace placeholders at runtime, e.g. using pythons .format()
• preserve multiline formatting for human readability regardless of editor

I currently solve this in 2 ways:

1. Python-approach: For projects with few (<5) prompt templates


prompts.py:

_prompt_template = r"""
This could be long and include placeholders like: {placeholder}

(...)

Such placeholders are replaced at runtime *using pythons .format()*.
"""

def get_prompt_template():
return _prompt_template[:]


code.py:

from prompts import get_date_quote_prompt_template

prompt_template = get_prompt_template()

prompt = prompt_template.format(
placeholder="some dynamic content")

2. YAML-approach: For projects with many prompt templates


prompts.yaml:

prompt_template: |
This could be long and include placeholders like: {placeholder}

(...)

Such placeholders are replaced at runtime *using pythons .format()*.


code.py:

import yaml

with open('prompts.yaml', 'r') as file:
config = yaml.safe_load(file)
prompt_template = config.get('prompt_template')

prompt = prompt_template.format(
placeholder="some dynamic content")

Is there some agreed upon best practice?
