str转化为list/tuple,直接进行转换即可。而由list/tuple转换为str,则需要借助join()函数来实现。join()函数是这样描述的: """ S.join(iterable) -> str Return a string which is the concatenation of the strings in the iterable. The separator between elements is S. ...

result = "".join(strings) 这里的操作是线性的,时间复杂度为 O(n)。 解决方案示例 假设我们有一个包含大量字符串的列表,我们想要将它们连接成一个单一的字符串: 代码语言:txt 复制 # 使用 + 运算符(不推荐) result = "" for s in large_list_of_strin...
In Python, joining a list of strings involves concatenating the elements of the list into a single string, using a specified delimiter to separate each element. This operation is particularly useful when you need to convert a list of strings into a single string, such as when you want to sa...
