折腾：
【未解决】EvernoteToWordpress出错：TypeError string indices must be integers
期间，
想要去实现：enum中，定义name外，再定义字符串值和int值
class BaiduOcrApiErrorCode(enum): QPS_LIMIT_REACHED = 'error_msg': 'image size error', 'error_code': 216202} RESP_ERR_CODE_ = 18 RESP_ERR_TEXT_QPS_LIMIT_REACHED = "Open api qps request limit reached" RESP_ERR_CODE_DAILY_LIMIT_REACHED = 17 RESP_ERR_TEXT_DAILY_LIMIT_REACHED = "Open api daily request limit reached"
之前记得弄过
去找找
python enum str int
python enum value str and int
python enum compound value
python enum tuple
import enum class EnumWithAttrs(enum.Enum): def __new__(cls, *args, **kwds): value = len(cls.__members__) + 1 obj = object.__new__(cls) obj._value_ = value return obj def __init__(self, a, b): self.a = a self.b = b GREEN = 'a', 'b' BLUE = 'c', 'd'
或
from enum import Enum
class Items(Enum):
GREEN = ('a', 'b')
BLUE = ('c', 'd')
def __init__(self, a, b):
self.a = a
self.b = b>>> class Swatch(AutoNumber): ... def __init__(self, pantone='unknown'): ... self.pantone = pantone ... AUBURN = '3497' ... SEA_GREEN = '1246' ...

去写代码试试

会报错：

说是：要集成AutoNumber
-》自动赋给number=数字的值：从1到N
其他额外的值，可以自己赋值
但是此处，自己是 要赋值2个，一个是int，一个是str
好像必须集成一种？
比如IntEnum？
刚注意到，前面例子：
from enum import Enum
class Items(Enum):
GREEN = ('a', 'b')
BLUE = ('c', 'd')
def __init__(self, a, b):
self.a = a
self.b = b中，都是str值
那去试试AutoNumber
发现要额外定义AutoNumber
算了。
搜搜看
EnumWithAttrs
python EnumWithAttrs
没有
python Enum With Attrs
import enum class EnumWithAttrs(enum.Enum): def __new__(cls, *args, **kwds): value = len(cls.__members__) + 1 obj = object.__new__(cls) obj._value_ = value return obj def __init__(self, a, b): self.a = a self.b = b GREEN = 'a', 'b' BLUE = 'c', 'd'
原来是：EnumWithAttrs是自定义类的名字。。。
试试：
# class BaiduOcrApiError(AutoNumber): class BaiduOcrApiError(Enum): """Baidu OCR API call response error 错误码 - 文字识别OCR https://ai.baidu.com/ai-doc/OCR/dk3h7y5vr """ def __new__(cls, *args, **kwds): value = len(cls.__members__) + 1 obj = object.__new__(cls) obj._value_ = value return obj # def __init__(self, errCode=1, errMsg="Unknown error"): def __init__(self, errCode=1, errMsg="Unknown error"): self.errCode = errCode self.errMsg = errMsg DAILY_LIMIT_REACHED = (17, "Open api daily request limit reached") QPS_LIMIT_REACHED = (18, "Open api qps request limit reached") IMAGE_SIZE_ERROR = (216202, "image size error")
结果：
调试，初始化后：
第一个enum变量初始化
看起来没问题。
然后
第二次运行了：__new__
value=2
问题依旧：
Exception has occurred: TypeError __call__() got an unexpected keyword argument 'errCode'
突然想到，先去试试：
respErrEnum = BaiduOcrApiError(errorCode, errorMsg)
结果：
报错：
Exception has occurred: TypeError Cannot extend enumerations
去试试：
from collections import namedtuple
from enum import Enum
class Status(namedtuple('Status', 'name description'), Enum):
READY = 'ready', 'I am ready to do whatever is needed'
ERROR = 'error', 'Something went wrong here'
def __str__(self) -> str:
return self.name的：

IMAGE_SIZE_ERROR = (216202, "image size error")结果：
Exception has occurred: TypeError object.__new__(BaiduOcrApiError) is not safe, use tuple.__new__() File "/Users/crifan/dev/dev_root/crifan/EvernoteToWordpress/EvernoteToWordpress/libs/crifan/baiduOcr.py", line 67, in __new__ obj = object.__new__(cls)
改为：
# obj = object.__new__(cls) obj = tuple.__new__(cls)
报错：

感觉是：
errMsg是内置的属性，不能用。
看来是：
Python内置变量属性，是蓝色的。
-》蓝色的，是内置属性
-》自己不能用
估计改个名字即可
def __new__(cls, errorCode=1, errorMsg="Unknown error"): value = len(cls.__members__) + 1 # obj = object.__new__(cls) obj = tuple.__new__(cls) obj._value_ = value obj.errorCode = errorCode obj.errorMsg = errorMsg return obj
结果：
可以设置值，但是：
没有新增自定义属性errorCode和errorMsg
respErrEnum = BaiduOcrApiError(errorCode, errorMsg)
依旧报错：
Exception has occurred: TypeError Cannot extend enumerations
那去想办法，传入named tuple
python named tuple
Point = namedtuple('Point', 'x y')
pt1 = Point(1.0, 5.0)
import collections
#Create a namedtuple class with names "a" "b" "c"
Row = collections.namedtuple("Row", ["a", "b", "c"])
row = Row(a=1,b=2,c=3) #Make a namedtuple from the Row class we created
print row #Prints: Row(a=1, b=2, c=3)
print row.a #Prints: 1
print row[0] #Prints: 1去试试
RespError = namedtuple("RespError", "errorCode errorMsg")
curRespError = RespError(errorCode, errorMsg)
respErrEnum = BaiduOcrApiError(curRespError)结果：
Exception has occurred: ValueError RespError(errorCode=216202, errorMsg='image size error') is not a valid BaiduOcrApiError File "/Users/crifan/dev/dev_root/crifan/EvernoteToWordpress/EvernoteToWordpress/libs/crifan/baiduOcr.py", line 194, in imageToWords respErrEnum = BaiduOcrApiError(curRespError)
试试：
class BaiduOcrApiError(tuple, Enum): def __new__(cls, errorCode=1, errorMsg="Unknown error"): # value = len(cls.__members__) + 1 # obj = object.__new__(cls) obj = tuple.__new__(cls) obj._value_ = errorCode # obj.errorCode = errorCode obj.errorMsg = errorMsg return obj
调用：
respErrTuple = (errorCode, errorMsg) respErrEnum = BaiduOcrApiError(respErrTuple)
结果：
Exception has occurred: TypeError not enough arguments for format string
用：
respErrEnum = BaiduOcrApiError(errorCode, errorMsg)
结果：
Exception has occurred: TypeError Cannot extend enumerations
Python enum init tuple Cannot extend enumerations
python enum value returns tuple
python create tuple enum
python initialize tuple enum
python enum int and string
先试试：
respErrEnum = BaiduOcrApiError((errorCode, errorMsg))
结果：
Exception has occurred: ValueError (216202, 'image size error') is not a valid BaiduOcrApiError
那试试：
直接新建一个空的，然后再去赋值
respErrEnum = BaiduOcrApiError() respErrEnum.errCode = errorCode respErrEnum.errMsg = errorMsg
结果：
报错：
Exception has occurred: TypeError __call__() missing 1 required positional argument: 'value' File "/Users/crifan/dev/dev_root/crifan/EvernoteToWordpress/EvernoteToWordpress/debug/baiduOcr/debugErrorEnum.py", line 55, in <module> respErrEnum = BaiduOcrApiError()
试试：
respErrEnum = BaiduOcrApiError(value=(errorCode, errorMsg))
结果：
Exception has occurred: ValueError (216202, 'image size error') is not a valid BaiduOcrApiError
去安装aenum试试
pip install aenum pipenv install aenum
结果：
from aenum import AutoNumberEnum class BaiduOcrApiError(AutoNumberEnum): _init_ = "errorCode errorMsg" DAILY_LIMIT_REACHED = (17, "Open api daily request limit reached") QPS_LIMIT_REACHED = (18, "Open api qps request limit reached") IMAGE_SIZE_ERROR = (216202, "image size error") if __name__ == "__main__": errorCode = 216202 errorMsg = 'image size error' respErrEnum = BaiduOcrApiError(errorCode, errorMsg)
结果：
Exception has occurred: TypeError cannot extend enumerations via subclassing
respErrEnum = BaiduOcrApiError((errorCode, errorMsg))
结果：
Exception has occurred: ValueError (216202, 'image size error') is not a valid BaiduOcrApiError
python enum dynamic
”extend_enum in action:
from aenum import extend_enum
extend_enum(Color, ‘white’, 1)
print Color, list(Color)
print repr(Color.black), Color.black, repr(Color.white), Color.white
“
去试试
也不对，此处是：
对enum进行扩展
此处不是想要扩展，而是想要：
判断当前的值，是否在enum中
但是此处，暂时的需求是：
只需要得知errorCode，即可够用，去判断此处的是否是其中2种，如果不是，else处理即可
另外，此处调试发现：
from enum import Enum class BaiduOcrApiError(tuple, Enum): def __new__(cls, errorCode=1, errorMsg="Unknown error"): # value = len(cls.__members__) + 1 # obj = object.__new__(cls) obj = tuple.__new__(cls) obj._value_ = errorCode obj.errorCode = errorCode obj.errorMsg = errorMsg return obj DAILY_LIMIT_REACHED = (17, "Open api daily request limit reached") QPS_LIMIT_REACHED = (18, "Open api qps request limit reached") IMAGE_SIZE_ERROR = (216202, "image size error")
竟然是：
即：
- errorCode = 17, “Open api daily request limit reached”
- errorMsg = （默认的）”Unknown error”
而不是以为的：
- errorCode=17
- errorMsg = “Open api daily request limit reached”
改为：
DAILY_LIMIT_REACHED = 17, "Open api daily request limit reached" QPS_LIMIT_REACHED = 18, "Open api qps request limit reached" IMAGE_SIZE_ERROR = 216202, "image size error"
结果：
问题依旧。
改为：
# def __new__(cls, errorCode=1, errorMsg="Unknown error"): def __new__(cls, errTuple=(1, "Unknown error")): errorCode = errTuple[0] errorMsg = errTuple[1] # value = len(cls.__members__) + 1 # obj = object.__new__(cls) obj = tuple.__new__(cls) obj._value_ = errorCode obj.errorCode = errorCode obj.errorMsg = errorMsg return obj
结果：
输入的值是对的，tuple
也还是只有value属性
没有自己加的
errorCode
errorMsg
问题依旧：
Exception has occurred: ValueError (216202, 'image size error') is not a valid BaiduOcrApiError
目前没法完全实现需求：
（1）定义一个enum，name的value是tuple的int和string
（2）然后从int和string，去动态创建enum
目前只能实现前者：
（1）定义一个enum，name的value是tuple的int和string
代码：
from enum import Enum class BaiduOcrApiError(tuple, Enum): errorCode = errTuple[0] errorMsg = errTuple[1] # value = len(cls.__members__) + 1 # obj = object.__new__(cls) obj = tuple.__new__(cls) obj._value_ = errorCode obj.errorCode = errorCode obj.errorMsg = errorMsg return obj DAILY_LIMIT_REACHED = (17, "Open api daily request limit reached") QPS_LIMIT_REACHED = (18, "Open api qps request limit reached") IMAGE_SIZE_ERROR = (216202, "image size error")
调用：
if errorCode == BaiduOcrApiError.QPS_LIMIT_REACHED.errorCode:
无法实现：
（2）然后从int和string，去动态创建enum
