可能有更快的方法来执行此操作，但不使用其他模块：
def tobits(s): result = [] for c in s: bits = bin(ord(c))[2:] bits = '00000000'[len(bits):] + bits result.extend([int(b) for b in bits]) return resultdef frombits(bits): chars = [] for b in range(len(bits) / 8): byte = bits[b*8:(b+1)*8] chars.append(chr(int(''.join([str(bit) for bit in byte]), 2))) return ''.join(chars)
