                  问题描述

                  Python 是否真的包含布尔值?我知道你可以这样做:

                  Does Python actually contain a Boolean value? I know that you can do:

                  checker = 1
                  if checker:
                      #dostuff
                  

                  但我很迂腐,喜欢在 Java 中看到布尔值.例如:

                  But I'm quite pedantic and enjoy seeing booleans in Java. For instance:

                  Boolean checker;
                  if (someDecision)
                  {
                      checker = true;
                  }
                  if(checker)
                  {
                      //some stuff
                  }
                  

                  Python 中是否有布尔值之类的东西?我似乎在文档中找不到类似的东西.

                  Is there such a thing as a Boolean in Python? I can't seem to find anything like it in the documentation.

                  推荐答案

                  checker = None 
                  
                  if some_decision:
                      checker = True
                  
                  if checker:
                      # some stuff

                  您的代码也可以工作,因为必要时 1 会转换为 True.实际上 Python 很久没有布尔类型了(就像在旧的 C 中一样),一些程序员仍然使用整数而不是布尔值.

                  Your code works too, since 1 is converted to True when necessary. Actually Python didn't have a boolean type for a long time (as in old C), and some programmers still use integers instead of booleans.
