Python why this if statement returns True?

Question

I am wondering why it returns True:

if False or True and True == True and (False == True or False == (not True)) or False and False and True:
    pass

doesn't it accept "and False" part in the end as False? doesn't all statements with "and" return True?

Answer 1

Starting with:

False or True and True == True and (False == True or False == (not True)) or False and False and True

Solve parentheses first:

(False == True or False == (not True))

Solve parentheses first - not True is False:

(False == True or False == False)

Next order of operation: ==:

((False == True) or (False == False))

Resulting in:

((False) or (True))

Next order of operation: or:

(True)

Now we have:

False or True and True == True and (True) or False and False and True

Next order of operation: ==:

False or True and (True == True) and True or False and False and True

Resulting in:

False or True and (True) and True or False and False and True

Next order of operation: and:

False or ((True and True) and True) or ((False and False) and True)

Resulting in:

False or ((True) and True) or ((False) and True)

And then:

False or (True) or (False)

Now the or operator:

((False or True) or False)

And then:

((True) or False)

Which results in True because True or False is True.
