Что выведет следующий код на Python?


a = 256
b = 256
c = 257
d = 257

print(a is b) # #1
print(c is d) # #2

print(True + True + True == 3) # #3
print(True is 1) # #4
print(False == 0) # #5
print(False is 0) # #6

D)

True
False

False


Правильный ответ: B

💡 Почему?
-
a is bTrue, потому что int от -5 до 256 кэшируются.
-
c is dFalse, число 257 не кэшируется.
-
True + True + True == 3True, более того, True == 1.
-
True is 1False — это разные типы (bool и int).
-
False == 0True, False is 0False.
