An alternative method to accomplish the same result would test whether the current item in the tuple is even (using if not num % 2:) and, if true, would add the current item to the running total.

实现相同结果的另一种方法是测试tuple中的当前项是否是偶数(使用if not num % 2：)，如果为真，那么将当前项添加到运行总和中。

If I'm inside this FOR, OK, and I'm running around, if I ever hit a place where this test is true, I'm going to execute that return, return that return returns from the entire procedure.

如果我是在这个for循环里面，我正在运行，如果我运行到test的值为真的地方，我就会执行，这个return将会返回整个程序的值，明白了吗？

youdao

So what's going to happen here? If I'm inside this FOR, OK, and I'm running around, if I ever hit a place where this test is true, I'm going to execute that return, return that return returns from the entire procedure. OK? So the return comes back from the procedure.

那么这里发生了什么呢？,如果我是在这个for循环里面，我正在运行，如果我运行到test的值为真的地方，我就会执行,这个return将会返回整个程序的值,明白了吗？所以它将会从整个程序中返回值。
