Using ChainMap to use configs with precedence

This is a simple code preview how to use ChainMap to combine multiple config files into one with precedence. Attaching also Jupyter Notebook.

from collections import ChainMap
from pprint import pprint
local_config = {
    "user": "localuser",
    "pass": "localpass",
    "host": "localhost"
}
global_config = {
    "user": "globaluser",
    "pass": "globalpass",
    "host": "globalhost",
    "timeout": 15
}
config = ChainMap(local_config, global_config)
pprint(config)
for k,v in config.items():
    print(f"{k}:{v}")
