当你执行声明时
a = myfunction()
如果不是什么,你想成为什么?

When you execute the statement
a = myfunction()
What do you want to be in a, if not None?

什么都不是,或者不是吗?
你可能打印这个功能,当然你需要什么。你可以称之为:
def x():
通过
print x()#call打印
x()#只打电话
x()打印什么都没有,甚至不打印;-)

Nothing is None, or isnt?
You probably print the function, what you neednt, of course. You can just call it:
def x():
pass
print x() # calling with printing
x() # calling only
x() prints really nothing, even not None ;-)

你是什么意思不要 t返回任何,反对返回
无?假设我有其中一个功能,并做了:
foo = noReturnValue()
print foo
您期望(想要?)发生什么?
What do you mean by "don''t return anything", as oppossed to returning
None? Let''s say I had one of those functions, and did:
foo = noReturnValue()
print foo
what would you expect (want?) to happen?
