Installation
To install humps, simply use pipenv (or pip, of course):
$ pipenv install pyhumps
Usage
Converting strings
import humps
humps.camelize("jack_in_the_box") # jackInTheBox
humps.decamelize("rubyTuesdays") # ruby_tuesdays
humps.pascalize("red_robin") # RedRobin
humps.kebabize("white_castle") # white-castle
Converting dictionary keys
import humps
array = [{"attrOne": "foo"}, {"attrOne": "bar"}]
humps.decamelize(array) # [{"attr_one": "foo"}, {"attr_one": "bar"}]
array = [{"attr_one": "foo"}, {"attr_one": "bar"}]
humps.camelize(array) # [{"attrOne": "foo"}, {"attrOne": "bar"}]
array = [{'attr_one': 'foo'}, {'attr_one': 'bar'}]
humps.kebabize(array) # [{'attr-one': 'foo'}, {'attr-one': 'bar'}]
array = [{"attr_one": "foo"}, {"attr_one": "bar"}]
humps.pascalize(array) # [{"AttrOne": "foo"}, {"AttrOne": "bar"}]
Checking character casing
import humps
humps.is_camelcase("illWearYourGranddadsClothes") # True
humps.is_pascalcase("ILookIncredible") # True
humps.is_snakecase("im_in_this_big_ass_coat") # True
humps.is_kebabcase('from-that-thrift-shop') # True
humps.is_camelcase("down_the_road") # False
humps.is_snakecase("imGonnaPopSomeTags") # False
humps.is_kebabcase('only_got_twenty_dollars_in_my_pocket') # False
# what about abbrevations, acronyms, and initialisms? No problem!
humps.decamelize("APIResponse") # api_response
Cookbook
Pythonic Boto3 API Wrapper
# aws.py
import humps
import boto3
def api(service, decamelize=True, *args, **kwargs):
service, func = service.split(":")
client = boto3.client(service)
kwargs = humps.pascalize(kwargs)
response = getattr(client, func)(*args, **kwargs)
return (depascalize(response) if decamelize else response)
# usage
api("s3:download_file", bucket="bucket", key="hello.png", filename="hello.png")
