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


🔢 Варианты ответа:

A)

C)

False
True
False
True
False


D)

True
False
False
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.

How Does Bitcoin Mining Work?

Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
