查询词典 bool

However, these methods can return any value, so if the comparison operator is used in a Boolean context (e.g., in the condition of an if statement), Python will call bool on the value to determine if the result is true or false.

但是这些方法也可以返回任何值，所以如果比较运算发生在布尔上下文中（例如 if 语句中的条件测试），Python会在返回值上调用函数 bool 确定返回值的真值。

Likewise, decrementing a bool sets the bool to its logically complemented value. C++ allows incrementing a bool (but marks the feature as deprecated, which means it might be removed in a future standard). C++ forbids decrementing a bool . C99 allows both.

同样的，对一个 bool 的递减把这个 bool 设置成它逻辑上的补码值。C++允许对 bool 的递增（但是把这个特性标记为弃用的，这表示它可能会在将来的标准中移出）。C++禁止对 bool 的递减。C99两者都允许。
