Let me check my pockets…
The Pockets library pulls together all the Python helper functions I’ve found useful over the years.
If you’ve worked on a project that exports an API and accesses a data store, you’ve probably seen some code that looks like this:
# Receive a data type with underscores from some API
data_type = 'user_preference'
# Convert underscored data type to CamelCase to match the data model
model_name = camel(data_type)
# Resolve the model name into a model class
model_class = resolve(model_name, modules=["webapp.model.admin",
"webapp.model.user",
"webapp.model.businesslogic"]
# Instantiate the model class and do stuff with the instance...
instance = model_class()
There’s an impedance mismatch any time you work with two different frameworks; especially when you want to update your back-end while maintaining legacy compatibility with an external API.
Pockets is full of highly tested, well maintained functions that help bridge the gap. Here are just a few examples…
Convert underscore_separated string to CamelCase
>>> from pockets import camel
>>> camel("xml_http_request", upper_segments=[1])
'XmlHTTPRequest'
Convert CamelCase string to underscore_separated
>>> from pockets import uncamel
>>> uncamel("XmlHTTPRequest")
'xml_http_request'
Resolve a string into an object
>>> from pockets import resolve
>>> resolve("calendar.TextCalendar")
<class 'calendar.TextCalendar'>
Peek ahead iterator
>>> from pockets import peek_iter >>> p = peek_iter(["a", "b", "c", "d", "e"]) >>> p.peek() 'a' >>> p.next() 'a' >>> p.peek(3) ['b', 'c', 'd']
