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。
My list:
te = [
{
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala",
"phone": "None"
},
{
"Name": "Bala",
"phone": "None"
}
]
删除重复值的函数：
def removeduplicate(it):
seen = set()
for x in it:
if x not in seen:
yield x
seen.add(x)
当我调用这个函数时我得到generator object.
<generator object removeduplicate at 0x0170B6E8>
当我尝试迭代生成器时，我得到TypeError: unhashable type: 'dict'
有没有办法删除重复值或迭代生成器
您可以通过字典理解轻松删除重复键，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
Output-
[{'phone': 'None', 'Name': 'Bala1'}, {'phone': 'None', 'Name': 'Bala'}]
