[warning] suggest braces around empty body in an 'if' statement [-wempty-bod

This warning suggests that it is a good practice to use braces around the body of an `if` statement even if it is empty. For example:

if (condition) {
    // do something
}

is preferred over:

if (condition)
    // do something

The latter is legal but can lead to mistakes or misunderstandings, especially when multiple statements are added to the `if` body later on. The suggestion is to use braces consistently to make the code more readable and maintainable.

suggest parentheses around assignment used as truth value

这个警告是Python中常见的一个警告。它通常出现在你试图将一个赋值语句用作条件表达式时。

在Python中，赋值语句本身并不返回任何值。因此，如果你使用一个赋值语句作为条件表达式，Python就会发出这个警告。

为了避免这个警告，你可以在赋值语句周围添加括号，明确地告诉Python你想要将赋值语句的结果作为条件表达式的值。例如，你可以这样做：

if (x := some_function()) is not None:
    # do something with x

在这个例子中，我们使用括号将赋值语句 `(x := some_function())` 括起来，以避免警告。同时，我们使用了 `is not None` 来判断赋值语句的结果是否为 None。
