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()
