当我们尝试在列表而不是字符串上调用split()方法时,会出现“AttributeError: 'list' object has no attribute 'split'”。 要解决该错误,我们要么必须更正变量的赋值并确保对字符串调用split(),要么对列表中字符串类型的元素调用split()。 我们可以访问特定索引处的列表,例如my_list[0]或者
Lastly, an important application of strings is thesplitmethod, which returns a list of all the words in the initial string and it automatically splits by any white space. It can optionally take a parameter and split the strings by another character, like a comma or a dot 4. Formatting str...
第 17 行使代码用 split 函数用逗号将字符串拆分成一个列表,列表中的每个值都是这行中某一列的值,然后,将列表赋给变量 row_list。 这里指定了这个分隔符参数,是为了防备你处理的输入文件或要写入的输出文件具有不同的分隔符,例如,分号(;)或制表符(\t)。
