[Python] Why is '(x in list_1) == True' is True but 'x in list_1 == True' is False? [duplicate]

I know this is can be a very basic question, but I found something curious on Python. I will try to explain this with the following example:

l = [1,2,3,4,5]
n1 = 1


We know the following:

print( n1 in l ) # True # is n1 in the list l1?
print( not(n1 in l) ) # False # is n1 not in the list l1?


instead of not I can use:

print( (n1 in l) == True ) # True
# this will be like
# True == True
# True


My question is when I don't use the parentheses, ex:

print( n1 in l == True ) # False


Here the answer from the console is False

I was trying to understand the logic about this

So if I try to do it step by step

n1 in l == True
l == True # this is False, l es not a boolean True, it is a list
n1 in False # this is not False, actually if you run it it will be an error

print( n1 in False) # TypeError: argument of type 'bool' is not iterable


Therefore, why if I run:

print( n1 in l == True )


The answer on the console is False?

Thanks a lot in advance.

print( n1 in l == True ) # True


to be the same as:

print( (n1 in l) == True ) # True
