Python 按字典dict的键排序,并取出相应的键值放于list中的实例

def dict_to_numpy_method1(dict):
 dict_sorted=sorted(dict.iteritems(), key=lambda d:d[0])
 results=[value for key,value in dict_sorted]

def dict_to_numpy_method2(dict):
 keys=dict.keys()
 keys.sort()
 results=[dic[key] for key in keys]

def dict_to_numpy_method3(dict):
 keys=dict.keys()
 keys.sort()
 results=map(dict.get,keys)
