来自@ m.wasowski的更清洁的方法，我正在结合他的想法尝试解决这个问题（仍然不确定这是否正是OP想要的，因为句子中的单词长度不一致）：

def text_to_bin(text, n_bin=16):
    if n_bin < 16 or n_bin > 36:
        print "n_bin must be >= 16 and <= 36"
    else:
        for word in text.split():
            word_ord = ['{}'.format(bin(int(hashlib.md5(word).hexdigest(), n_bin)))]
            print '{} {}'.format(word, ''.join(word_ord)[2:])

text_to_bin('A cat in the woods', 16)

Answer 2

>>> import hashlib
>>> s="cat"
>>> hashcode=hashlib.md5(s).hexdigest()
>>> bin(int(hashcode,16))
'0b11010000011101111111001001000100110111101111100010100111000011100101111010100111010110001011110110000011010100101111110011011000'

Answer 3

你可以使用bin（）函数

bin(d077ff) # Result: '0b11...'

删除0b你可以这样做：

int(str(temp)[2:])

Answer 4

有点晚了，但是尝试一下：

binhashcode = ''.join(bin(int(i,16)).zfill(4) for i in hashcode)
