Python函數，返回False和None

Question

我有這個功能

def postData():
    data = doPOst()
    if data.result == "success":
       return data
    if data.result == "fail":
       return false

然后我根據回報我必須做類似的事情

if ret is None:
   pass # 1
if ret is False:
   pass # 2
else:
   normal

我想知道None和False會混在一起嗎

Answer 1

如果您明確檢查None和False ，則不會，它們將不會合並。

if ret is None: # entered only on None
    pass
elif ret == False: # entered only on False or 0
    pass
else:
    pass

如果僅檢查真實/錯誤值，它們將被合並：

if ret:
    pass
else: # entered on None or False
    pass
