libb.CaseInsensitiveDict

class CaseInsensitiveDict(data=None, **kwargs)

Bases: MutableMapping

A case-insensitive dictionary-like object.

Implements all methods and operations of MutableMapping as well as dict’s copy. Also provides lower_items.

All keys are expected to be strings. The structure remembers the case of the last key to be set, and iter(instance), keys(), items() will contain case-sensitive keys. However, querying and contains testing is case insensitive:

cid = CaseInsensitiveDict() cid[‘Accept’] = ‘application/json’ cid[‘aCCEPT’] == ‘application/json’ # True list(cid) == [‘Accept’] # True

For example, headers['content-encoding'] will return the value of a 'Content-Encoding' response header, regardless of how the header name was originally stored.

Note

If the constructor, .update, or equality comparison operations are given keys that have equal .lower() values, the behavior is undefined.

lower_items()

Like iteritems(), but with all lowercase keys.

Example:

>>> cid = CaseInsensitiveDict({'Content-Type': 'application/json'})
>>> list(cid.lower_items())
[('content-type', 'application/json')]

copy()
