Question

我到处搜索并找到re.split以查找正常的字符串，但无法在df中使用它

这是与类似问题的不同之处-我需要语法将我的解决方案一次应用于整个列，而不仅仅是一个字符串

我以前使用过

但是有时候我有4或5个空格很好，而其他时候我有10个空格，所以我得到空列

我需要定义4个或更多空格并在熊猫中工作的东西

任何帮助，不胜感激！

Answer 1

尝试此正则表达式

(\s{4,})

的空白 {4，}至少4次

Answer 2

您可以尝试以下方法：

keeptemp = myalerts['Temp'].str.split(" +",expand = True)

“ +”表示一个或多个空格

将熊猫数据框字符串拆分为多个空格
