示例1: copy
# 需要導入模塊: from UserDict import DictMixin [as 別名]
# 或者: from UserDict.DictMixin import setdefault [as 別名]
def copy(self):
"""
Return a C{dict} mapping each header name to the last corresponding
header value.
"""
return dict(self.items())
# Python 2.3 DictMixin.setdefault is defined so as not to have a default
# for the value parameter. This is necessary to make this setdefault look
# like dict.setdefault on Python 2.3. -exarkun 示例2: setdefault
# 需要導入模塊: from UserDict import DictMixin [as 別名]
# 或者: from UserDict.DictMixin import setdefault [as 別名]
def setdefault(self, name, value=None):
"""
Retrieve the last value for the given header name. If there are no
values present for that header, set the value to C{value} and return
that instead. Note that C{None} is the default for C{value} for
backwards compatibility, but header values may only be of type C{str}.
"""
return DictMixin.setdefault(self, name, value)
# The remaining methods are only for efficiency. The same behavior
# should remain even if they are removed. For details, see
