我有一个看起来像这样的数据框：
Film Description
0 Batman Viewed in 2021-10-04T14:30:31Z City Hall, London
1 Superman Aired 2012-01-04R11:01:10Z in the USA first
2 Hulk 2010-07-04S07:22:02Z Still being produced
我想从“说明”列的每一行中删除日期时间，如下所示：
Film Description
0 Batman Viewed in City Hall, London
1 Superman Aired in the USA first
2 Hulk Still being produced
我已经尝试过此字符串正则表达式：
df['Description'] = df['Description '].str.replace(r'\^(\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2})Z', '')
\^ 匹配插入符号。
除此之外T，我看R和S在日期时间的邮票，他们必须加入。
使用
\s*\b\d{4}-\d{2}-\d{2}[TRS]\d{2}:\d{2}:\d{2}Z\b
见证明。
