If you forget them, then you won’t be calling the function but referencing it as a function object. To make your functions return a value, you need to use the Python return statement. That’s what you’ll cover from this point on. Remove ads...

The standard operation of division, which is performed by the/operator, generally returns a floating-point result. The returned result (quotient) can be an integer only if the first operand (dividend) is evenly divisible by the second operand (divider), or, in other words, it is divided wit...
When an exception occurs, it may have an associated value, also known as the exception’sargument. The presence and type of the argument depend on the exception type. 当发生异常时,它可能有个关联值,也叫做异常的参数。这个参数的类型以及是否有这个参数取决于异常类型。
