MultiDict

Create a dict that is a view on the given list

Create a dict from a cgi.FieldStorage instance

Add the key and value, not overwriting any previous value.

Return a list of all values matching the key (may be an empty list)

Get one value matching the key, raising a KeyError if multiple values were found.

Returns a dictionary where the values are either single values, or a list of values when a key/value appears more than once in this dictionary. This is similar to the kind of dictionary often used to represent the variables in a web request.

Returns a dictionary where each key is associated with a list of values.
