multidict¶
Multidicts are useful for working with HTTP headers, URL query args etc.
The code was extracted from aiohttp library.
Introduction¶
HTTP Headers and URL query string require specific data structure:
multidict. It behaves mostly like a regular dict
but it may have
several values for the same key and preserves insertion ordering.
The key is str
(or istr
for case-insensitive
dictionaries).
multidict
has four multidict classes:
MultiDict
, MultiDictProxy
, CIMultiDict
and CIMultiDictProxy
.
Immutable proxies (MultiDictProxy
and
CIMultiDictProxy
) provide a dynamic view for the
proxied multidict, the view reflects underlying collection changes. They
implement the Mapping
interface.
Regular mutable (MultiDict
and CIMultiDict
) classes
implement MutableMapping
and allows to change
their own content.
Case insensitive (CIMultiDict
and
CIMultiDictProxy
) ones assume the keys are case
insensitive, e.g.:
>>> dct = CIMultiDict(key='val')
>>> 'Key' in dct
True
>>> dct['Key']
'val'
Keys should be either str
or istr
instance.
The library has optional C Extensions for sake of speed.

The project is hosted on GitHub
Please file an issue on the bug tracker if you have found a bug or have some suggestion in order to improve the library.
The library uses Azure Pipelines for Continuous Integration.
