Python模拟中的模拟属性？

您正在将字符串传递给bin()函数：>>> bin('10')Traceback (most recent call last):  File "<stdin>", line 1, in <module>TypeError: 'str' object cannot be interpreted as an index给它一个整数来代替：>>> bin(10)'0b1010'通过将raw_input()结果转换为int()：n = int(raw_input())提示：您可以通过给负片跨度轻松地反转字符串：>>> 'forward'[::-1]'drawrof'因此您可以将功能简化为：def reversebinary():    n = int(raw_input())    bin_n = bin(n)[2:]    revbin = bin_n[::-1]    return int(revbin, 2)甚至：def reversebinary():    n = int(raw_input())    return int(bin(n)[:1:-1], 2)
