Python function, returning False and None

Question

I have this function

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

Then i based on return i have to do something like

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

I want to know that will None and False get mixed

Answer 1

If you check for None and False explicitly, then no, they will not get combined.

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

If you just checked for truthy/falsey values, they would get combined:

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