这是小川的第377次更新,第404篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第238题(顺位题号是1009).每个非负整数N都具有二进制表示.例如,5可以二进制表示为"101",11可以二进制表示为"1011",依此类推. 请注意,除N = 0外,任何二进制表示中都没有前导零. 二进制表示的补码是将1改为0和将0改为1时得到的二进制数.例如,二进制中"101"的补码是二进制的"010". 对于…

问题描述: 在用pthon写脚本得过程中,发生错误,ValueError: invalid literal for int() with base 10,这种错误是值得类型转换错误,int()函数是可以将字符串转换为整形,但是这个字符串如果是带小数得,比如‘470.00’,这个时候如果你再用int(‘470.00’)转换得话,就会出现上面报得错误. 解决方案: 这个时候可以用float()函数处理这个问题,在你不确定这个字符串是整形还是浮点数得情况下,用float()比较好,这样可以避免出现错误…
