Animal case convert recursively your dict/json keys to camelCase or snakeCase.
Based on https://github.com/rafa-acioly/animal_case
Most commonly used to build proxies when we need to create communication between apis that have different syntaxes on their endpoint.
Imagine that you have to make a get request on some endpoint and send a post request to another endpoint with some mutate data comming from the first request but each of there endpoints have differents json key sintaxies, now you have to convert all the keys recursively and the hell begins...fear no more my friend.

Converting dict keys recursively
By default parse_keys convert keys to snake_case
from animal_case.convert import parse_keys
my_dict = {
"firstKey": "first value",
"secondKey": "second value",
"thirdKey": [
{"subThirdKey": 1},
{"subThirdKey2": 2},
{"subThirdKey3": [
{"superDeep": "wow"}
]
}
]
}
converted = parse_keys(my_dict)
# output
'''
{
"first_key": "first value",
"second_key": "second value",
"third_key": [
{"sub_third_key": 1},
{"sub_third_key2": 2},
{"sub_third_key3": [
{"super_deep": "wow"}
]
}
]

If you'd like to keep some keys from being converted, you can pass preserve_regex
to any of the methods. For example, if you wanted to preserve CONSTANT_CASE,
you would do
from animal_case.convert import to_snake_case
converted = to_snake_case('CONSTANT_CASE', preserve_regex="^[A-Z0-9_]+$")
print(converted # output: CONSTANT_CASE
