1、写函数采用 %2 的方式来算。 >>> binary = lambda n: '' if n==0 else binary(n/2) + str(n%2) >>> binary(5) '101' >>> 2、采用python自带了方法 bin 函数,比如 bin(12345) 回返回字符串 '0b11000000111001', 这个时候在把0b去掉即可: >>> bin(12345).replace('0b','') '11000...

bin(x) Convert an integer number to a binary string. The result is a valid Python expression. If x is not a Python int object, it has to define an __index__() method that returns an integer. oct(x) Convert an integer number to an octal string. The result is a valid Python expre...
使用Python内置函数:bin()、oct()、int()、hex()可实现进制转换。 先看Python官方文档中对这几个内置函数的描述: bin(x) Convert an integer number to a binary string. The result is a valid Pyth
