Python类自值错误，预期类型为'str'的是Tuple [str]，而是使ClientSecretCredential

问题描述

我已经创建了一个类，并尝试将其值之一分配给需要字符串的内容，但是它却说它正在获取Tuple[str]，而我不知道怎么做？

from azure.identity import ClientSecretCredential


class ServicePrincipal:
    """
    Service Principal class is used to authorise the service
    """
    def __init__(self):
        self.tenant_id = "123-xyz",self.client_id = "123-abc",self.client_secret = "123-lmn",def credentials(self):
        """
        Returns a ClientServiceCredential object using service principal details
        :return:
        """
        # ISSUE IS HERE 
        return ClientSecretCredential(
            tenant_id=self.tenant_id,# <---- Getting Tuple[str]
            client_id=self.client_id,# <---- Getting Tuple[str]
            client_secret=self.client_secret,# <---- Getting Tuple[str]
        )

如果我复制将字符串直接粘贴到参数中就可以了。那么self.value某种程度上引起了问题？

解决方法

您应在此处删除逗号：

def __init__(self):
        self.tenant_id = "123-xyz",# remove the comma
        self.client_id = "123-abc",# remove the comma
        self.client_secret = "123-lmn",# remove the comma

逗号使变量成为元组
