pysnmp报错caused by <class 'TypeError'>: <lambda>() takes 3 positional arguments but 4 were given

这个错误通常是因为在使用 `pysnmp` 库时,传递了不正确的参数或参数数量不匹配。具体来说,可能是因为您在使用回调函数时,参数个数不正确。
例如,在使用 `pysnmp` 库时,如果您使用了类似于以下的代码:
```python
from pysnmp.hlapi.asyncore import *
def cbFun(snmpEngine, sendRequestHandle, errorIndication,
errorStatus, errorIndex, varBinds):
# do something
snmpEngine = SnmpEngine()
getCmd(snmpEngine,
CommunityData('public', mpModel=0),
UdpTransportTarget(('demo.snmplabs.com', 161)),
ContextData(),
ObjectType(ObjectIdentity('SNMPv2-MIB', 'sysDescr', 0)),
cbFun)
```
则可能会出现 `TypeError` 错误,因为 `cbFun` 函数需要 6 个参数,但是在这里只传递了 5 个参数。
如果您可以提供更多的代码和错误信息,或者进一步描述您的问题,我可以给出更详细的解决方案。

TypeError: __init__() takes 6 positional arguments but 23 were given
This error message means that you are calling the `__init__` method of a class with too many arguments. The `__init__` method is the constructor method of a class, and it is called when you create a new instance of the class.
In this case, you are passing 23 arguments to the `__init__` method, but it only expects 6. This could be caused by a number of things, such as passing in too many arguments when creating a new instance of the class, or passing in the wrong types of arguments.
To fix this error, you should review the code that is creating the instance of the class and make sure that you are passing in the correct number and types of arguments. You may also need to review the definition of the class to make sure that the `__init__` method is expecting the correct number of arguments.
