从python中的列表中删除重复的JSON对象
我有一个字典列表,其中特定值重复多次,我想删除重复的值。
我的清单:
te = [ {
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala",
"phone": "None"
}
]
删除重复值的功能:
def removeduplicate(it): seen = set()
for x in it:
if x not in seen:
yield x
seen.add(x)
当我调用此函数时,我得到了generator object
。
<generator object removeduplicate at 0x0170B6E8>
当我尝试遍历生成器时,我得到 TypeError: unhashable type: 'dict'
有没有办法删除重复的值或遍历生成器
回答:
您可以通过字典理解轻松地删除重复键,因为字典不允许重复键,如下所示-
te = [ {
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala1",
"phone": "None"
}
]
unique = { each['Name'] : each for each in te }.values()
print unique
输出-
[{'phone': 'None', 'Name': 'Bala1'}, {'phone': 'None', 'Name': 'Bala'}]
