python: how to convert a valid uuid from String to UUID?
提问by daydreamer
I receive the data as
我收到的数据为
{
"name": "Unknown",
"parent": "Uncategorized",
"uuid": "06335e84-2872-4914-8c5d-3ed07d2a2f16"
},
and I need to convert the uuidfrom Stringto uuid
我需要将uuidfrom转换String为uuid
I did not find a way on the python docs, or am I missing something basic here?
我没有在python 文档上找到方法，或者我在这里遗漏了一些基本的东西？

Just pass it to uuid.UUID:
只需将其传递给uuid.UUID：
import uuid
o = {
"name": "Unknown",
"parent": "Uncategorized",
"uuid": "06335e84-2872-4914-8c5d-3ed07d2a2f16"
}
print uuid.UUID(o['uuid']).hex

If the above answer didn't work for you for converting a valid UUID in string format back to an actual UUID object... using uuid.UUID(your_uuid_string)worked for me.
如果上述答案对您将字符串格式的有效 UUID 转换回实际 UUID 对象不起作用...使用uuid.UUID(your_uuid_string)对我有用。
In [6]: import uuid
...:
...: o = {
...: "name": "Unknown",
...: "parent": "Uncategorized",
...: "uuid": "06335e84-2872-4914-8c5d-3ed07d2a2f16"
...: }
...:
...: print uuid.UUID(o['uuid']).hex
...: print type(uuid.UUID(o['uuid']).hex)
06335e84287249148c5d3ed07d2a2f16
<type 'str'>
In [7]: your_uuid_string = uuid.UUID(o['uuid']).hex
In [8]: print uuid.UUID(your_uuid_string)
06335e84-2872-4914-8c5d-3ed07d2a2f16
In [9]: print type(uuid.UUID(your_uuid_string))
<class 'uuid.UUID'>

Don't call .hexon the UUID object unless you need the string representation of that uuid.
不要调用.hexUUID 对象，除非您需要该 uuid 的字符串表示。
>>> import uuid
>>> some_uuid = uuid.uuid4()
>>> type(some_uuid)
<class 'uuid.UUID'>
>>> some_uuid_str = some_uuid.hex
>>> some_uuid_str
'5b77bdbade7b4fcb838f8111b68e18ae'
>>> type(some_uuid_str)
<class 'str'>
Then as others mentioned above to convert a uuid string back to UUID instance do:
然后正如上面提到的将 uuid 字符串转换回 UUID 实例的其他人所做的：
>>> uuid.UUID(some_uuid_str)
UUID('5b77bdba-de7b-4fcb-838f-8111b68e18ae')
>>> (some_uuid == uuid.UUID(some_uuid_str))
True
>>> (some_uuid == some_uuid_str)
False
You could even set up a small helper utility function to validate the strand return the UUID back if you wanted to:
如果需要，您甚至可以设置一个小的辅助实用程序函数来验证str并返回 UUID：
def is_valid_uuid(val):
try:
return uuid.UUID(str(val))
except ValueError:
return None
Then to use it:
然后使用它：
>>> some_uuid = uuid.uuid4()
>>> is_valid_uuid(some_uuid)
UUID('aa6635e1-e394-463b-b43d-69eb4c3a8570')
>>> type(is_valid_uuid(some_uuid))
<class 'uuid.UUID'>
