求解方法：
1、整数求余
2、重复进行，整数除2再求余，直到除数为0
3、拼接余数
4、反转字符串
def int2two(intNo): twoStr=‘‘ if intNo == 0: twoStr = ‘0‘ while intNo != 0: intMod = intNo % 2 intNo = intNo//2 twoStr = twoStr + str(intMod) return ‘0b%08d‘ %int(twoStr[::-1]) if __name__ == ‘__main__‘: print(int2two(2796202)) print(bin(2796202))
运行结果：
