[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.

[warning] suggest parentheses around assignment used as truth value [-wparentheses]

[警告]建议在将赋值用作真值时加上括号[-wparentheses]

这个警告是由于在条件语句中使用了赋值语句而产生的。在Python中，赋值语句是有返回值的，但是它们的返回值通常不是我们想要的。因此，建议在条件语句中使用括号来明确赋值和比较的优先级，以避免出现意外的结果。例如：

if (x := 5) == 5:
print("x is 5")

这里，我们使用括号将赋值语句和比较语句分开，以避免出现警告。
