Question

有人可以帮我确定为什么我会在代码中出现循环错误之外的问题吗？我也尝试将它包含在if语句中，我也得到了同样的错误。

12:20:32＃。/ datasource_config.py 文件“./datasource_config.py”，第90行打破 SyntaxError：'break'在循环外部

有问题的代码：

print " Checking for the existence of JAASAUTHDATA :"+ alias1

您的break 在循环之外。缩进问题：

for jaasAuthId in jaasAuthDataList:
    getAlias = AdminConfig.showAttribute(jaasAuthId, "alias")
    if (cmp(getAlias,alias1) == 0):
        print " JAASAuthData exists with name :"+ alias1
        print " Removing JAASAuthData with name :"+ alias1
        AdminConfig.remove(jaasAuthId)
        print " JAASAuthData removed " 
        AdminConfig.save()
        print " Saving Configuraion " 
        matchFound = 1
    break

你可能还需要在下面缩进多行，我不能确定这一点，但这很重要。
