如果list变量和list函数重名,会有什么后果呢?我们可以参考如下代码: list = ['泡芙', '汤圆', '鱼儿', '骆驼'] tup_1 = (1, 2, 3, 4, 5) tupToList = list(tup_1) print(tupToList) 代码运行后出错了,出错原因是TypeError: 'list' object is not callable Traceback (most recent call last): File "D:/python_workshop/…

跟着欢迎进入Flask大型教程项目!的教程学习Flask,到了重构用户模型的时候,运行脚本后报错: TypeError: 'bool' object is not callable 这是用户模型: class User(db.Model): id = db.Column(db.Integer, primary_key=True) nickname = db.Column(db.String(64), index=True, unique=True) email = db.Column(db.St…
