I just stumbled across this and I couldn't find a sufficient answer:
x = ""
Why then is:
x == True
False
x == False
False
x != True
True
x != False
True
Am I supposed to conclude that x is neither True nor False?
to check whether x is True or False:
bool("")
> False
bool("x")
> True
for details on the semantics of is and == see this question
Am I supposed to conclude that x is neither True nor False?
That's right. x is neither True nor False, it is "". The differences start with the type:
>>> print(type(""), type("x"), type(True), type(False))
builtins.str, builtins.str, builtins.bool, builtins.bool
Python is a highly object oriented language. Hence, strings are objects. The nice thing with python is that they can have a boolean representation for if x: print("yes"), e. g.. For strings this representation is len(x)!=0.
