SOme interesting notes:

X // y: Floor division

Unlimited prevision integers are convenient

Complex numbers:  (2+1j)**3

Octal literals: 0o1, 0o20, 0o377, oct(64)

Hex literals: 0x01, 0x10, 0xFF, hex(64)

Binary: 0b1, 0b10000, 0b111111, bin(64)

string formatting: '%o, %x, %X' %(64, 64, 255)

Bitwise operations: | << >> &

Decimals are fixed point float
