布尔在Python [英] Boolean in Python
问题描述
Python中是否实际包含一个布尔值?我知道,你可以这样做:
检查= 1
如果检查:
#做东西
不过,我很迂腐,享受在Java中看到的布尔值。例如:
布尔检查;
如果(someDecision)
{
检查= TRUE;
}
如果(检查)
{
//一些东西
}
有没有这样的事情,因为这在Python?我似乎无法找到文档中这样的事情。
检查=无#没有必要如果some_decision:
检查=真如果检查:
#一些东西
有关详细信息:<一href=\"http://docs.python.org/library/functions.html#bool\">http://docs.python.org/library/functions.html#bool
您code工作过,因为1转换为真时,必要的。
其实Python中没有一个boolean型的很长一段时间(如在老C),以及一些程序员利用窗台的整数,而不是布尔值。
Does Python actually contain a Boolean value? I know that you can do:
checker = 1
if checker:
#dostuff
But I'm quite pedantic and enjoy seeing booleans in Java. For instance:
Boolean checker;
if (someDecision)
{
checker = true;
}
if(checker)
{
//some stuff
}
Is there such a thing as this in Python? I can't seem to find anything like it in the documentation.
checker = None # not necessary
if some_decision:
checker = True
if checker:
# some stuff
[Edit]
For more information: http://docs.python.org/library/functions.html#bool
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 sill use integers instead of booleans.
