Python: Accessing YAML values using “dot notation”

Question

I\'m using a YAML configuration file. So this is the code to load my config in Python:

import os
import yaml
with open(\'./config.yml\') as file:
    config

I ended up using python-box. This package provides multiple ways to read config files (yaml, csv, json, ...). And not only that, it allows you to pass dict or strings directly:

from box import Box
import yaml # Only required for different loaders

# Pass dict directly
movie_box = Box({ "Robin Hood: Men in Tights": { "imdb stars": 6.7, "length": 104 } })

# Load from yaml file
# Here it is also possible to use PyYAML arguments, 
# for example to specify different loaders e.g. SafeLoader or FullLoader
conf = Box.from_yaml(filename="./config.yaml", Loader=yaml.FullLoader) 

conf.mysql.user.pass

A lot more examples, are available in the Wiki.
