Replace string in a nested Dictianory.

[SpongeB0B]

Hi everyone,

I've got a huge nested dict from a yaml call

with open('MyYamlFile.yml', 'r') as file:
	yml_test = yaml.safe_load(file)

I would like to do ~a

yml_test.replace('wrong','right')

But of course we can't call a .replace on a Dict... :/

So how could I change ALL string that are nested / embedded within the yml_test ?

Thanks.

Can write a own solution usually a recursive approach that would traverse the dictionary.
Or use a solution that dos this eg nested-lookup.
Test.

from nested_lookup import nested_lookup
from nested_lookup import nested_update

nested_dict = {
    'level1': {
        'level2a': {
            'level3a': {
                'value': 1
            },
            'level3b': {
                'value': 2
            }
        },
        'level2b': {
            'level3c': {
                'value3': 3
            }
        }
    }
}

>>> result = nested_update(nested_dict, key='value', value=99)
>>> result
{'level1': {'level2a': {'level3a': {'value': 99}, 'level3b': {'value': 99}},
            'level2b': {'level3c': {'value3': 3}}}}
>>> 
>>> result = nested_update(result, key='value3', value=['hello', 100])
>>> result
{'level1': {'level2a': {'level3a': {'value': 99}, 'level3b': {'value': 99}},
            'level2b': {'level3c': {'value3': ['hello', 100]}}}}
