• 二进制、八进制和十六进制转换

x = 1234

print(bin(x))
print(oct(x))
print(hex(x))
print(format(x, 'b'))
print(format(x, 'o'))
print(format(x, 'x'))

x = -1234
print(format(x, 'b'))
print(format(x, 'x'))
print(format(2 ** 32 + x, 'b'))
print(format(2 ** 32 + x, 'x'))
print(int('4d2', 16))
print(int('10011010010', 2))
