下面是我们所实现代码的类图,它展示了与字符串转整数相关的逻辑。 "requests input""throws error"UserInput+get_input()+check_digit()StringConverter+to_integer()ErrorHandler+handle_conversion_error() 结束语 总结一下,字符串强转为整数在Python中相对简单,但为了处理各种异常情况,我们需要有周全的考虑。确保...
题目来源: https://leetcode.com/problems/string-to-integer-atoi/ 题意分析: 这道题也是简单题,题目意思是要将字符串转化成int。比如‘123’转成123. 题目思路: 由于有一些其他的输入直接用int()函数肯定是不可以的。比如说‘123b’用int()函数肯定是报错的。那么我们可以用一个ans = 0来初始化得到的int...
