Question

我有以下文字

04/20/2009; 04/20/09; 4/20/09; 4/3/09
Mar-20-2009; Mar 20, 2009; March 20, 2009; Mar. 20, 2009; Mar 20 2009;
20 Mar 2009; 20 March 2009; 20 Mar. 2009; 20 March, 2009
Mar 20th, 2009; Mar 21st, 2009; Mar 22nd, 2009
Feb 2009; Sep 2009; Oct 2010
6/2008; 12/2009
2009; 2010

我的想法是将所有日期替换为一种格式，但是我需要将所有日期设置为一个pd.Series列对象。

这是我到目前为止所做的。

with open('dates.txt') as file:
    for row in file:
        doc.append(line)

我想要类似
