方法一:使用for循环遍历字符串 最常见的遍历字符串的方法是使用for循环。在Python中,字符串被视为一个序列,可以像遍历其他序列一样遍历字符串。下面是一个示例代码: string="Hello, World!"forcharinstring:print(char) 1. 2. 3. 上述代码中,我们定义了一个字符串string,然后使用for循环遍历字符
void output_postion(const char* a, const char* b); 如：a = "abdbcc" b = "abc"...

循环若干次这里用了while循环,可以使用for _ in range(x)的方式替代 把随机数字当作索引然后从字符串中取值,可以直接使用random.choice()函数替代 RandomChar中的对象属性和对象方法,可直接定义成类属性和类方法 ‘ABCDEFGHIJKLMNOPQRSTUVWXYZ’ 这类字符集合不需要手工书写,使用string模块即可获取,如string.ascii_upper...
The string whose method is called is inserted in between each given string. The result is returned as a new string. Example: '.'.join(['ab', 'pq', 'rs']) -> 'ab.pq.rs' 连接任意数量的字符串。 调用其方法的字符串被插入到每个给定字符串之间。
