Python從OrderedDict中提取值

Question

如何從Python中的OrderedDict中拖出'FirstName'？

OrderedDict([(u'totalSize', 1), 
      (u'done', True), 
      (u'records', 
      [OrderedDict([ 
      (u'attributes', 
      OrderedDict([ 
      (u'type', u'Contact'), 
(u'url',u'/services/data/v38.0/sobjects/Contact/003290000089vSgAAI')])), 
(u'FirstName', u'John'), (u'LastName', u'Smith')])])]) 

Answer 1

>>> from collections import OrderedDict 
>>> a = OrderedDict([('totalSize', 1), ('done', True), ('records', [OrderedDict([('attributes', OrderedDict([('type', 'Contact'), ('url', '/services/data/v38.0/sobjects/Contact/003290000089vSgAAI')])), ('FirstName', 'John'), ('LastName', 'Smith')])])]) 
>>> a['records'][0]['FirstName'] 
'John'
