Python 将十进制整数转为二进制

import math
n=16
def ten_two(n,num):
    """
    将num转换为二进制
    :param n:
    :param num: num<n
    :return:
    """
    result = [0 for i in range(int(math.log(n,2)))] #二进制初始化
    num_two = bin(num)  # 将num转换为二进制 如5结果为0b101
    num_two = str(num_two[2:])  # 去除0b 格式为字符
    geshu = int(len(result)) - int(len(num_two))
    result1 = [0 for i in range(geshu)]
    result1.extend([int(i) for i in num_two])
    return result1

print(ten_two(16,15))
