str.join() 列表中的多个字符串拼接 高效 f-string 变量嵌入和格式化(Python 3.6+) 高效 StringIO 循环中频繁拼接 高效 总结 少量拼接:直接用 + 或 f-string。 批量拼接:优先用 str.join()。 格式化需求:f-string 或 format()。 高性能场景:StringIO 或列表缓存后 join()。
The split() method is the most common way to convert a string into a list by breaking it at a specified delimiter. string = "apple,banana,cherry" list_of_fruits = string.split(",") print(list_of_fruits) # Output: ['apple', 'banana', 'cherry'] Copy 2. Using List Comprehension ...
