Syntax for an If statement using a boolean
提问by Lucidity
I just recently joined the python3 HypeTrain. However I just wondered how you can use an if statement onto a boolean. Example:
我最近才加入了 python3 HypeTrain。但是我只是想知道如何在布尔值上使用 if 语句。例子：
RandomBool = True
# and now how can I check this in an if statement? Like the following:
if RandomBool == True:
#DoYourThing
And also, can I just switch the value of a boolean like this?
而且，我可以像这样切换布尔值吗？
RandomBool1 == True #Boolean states True
if #AnyThing:
RandomBool1 = False #Boolean states False from now on?

if randombool == False
but you can also use:
但你也可以使用：
if not randombool:
