问题描述

我正在尝试更改csv文件中UTC时间戳的格式，但是似乎没有任何效果.它总是说有一个ValueError 与格式'％m/％d/％Y％I:％M:％S％p'不匹配下面是CSV列的示例

I am trying to change the format of a UTC timestamp in a csv file but nothing seems to be working. It keeps saying that there is a ValueError does not match format '%m/%d/%Y %I:%M:%S %p' Below there is an example of the CSV column

CSV列示例

df[' UTC Event Timestamp'] = df[' UTC Event Timestamp'].astype(str)
string_col = str(df)
string_col.strip()

datetime.strptime(string_col, '%m/%d/%Y %I:%M:%S %p')
datetime.strptime(string_col, '%m/%d/%Y %I:%M:%S %p').strftime('%d/%m/%Y %I:%M:%S %p')

print(string_col)

推荐答案

您可以使用

df['string_col'].apply(lambda row: datetime.strptime(row, '%m/%d/%Y %I:%M:%S %p').strftime('%d/%m/%Y %I:%M:%S %p'))

将列转换为日期时间格式.
