[英]Python: How to change a UTC timestamp from mm/dd/yyyy hh:mm:ss AM to dd/mm/yyyy hh:mm:ss AM
I am trying to change the format of a UTC timestamp in a csv file but nothing seems to be working.我正在尝试更改 csv 文件中 UTC 时间戳的格式,但似乎没有任何效果。 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一直说有一个 ValueError
does not match format '%m/%d/%Y %I:%M:%S %p'
下面是 CSV 列的示例
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)
df['UTC Event Timestamp'] = pd.to_datetime(df['UTC Event Timestamp'])
df['UTC Event Timestamp'] = df['UTC Event Timestamp'].apply(lambda x: x.strftime('%d/%m/%Y %I:%M:%S %p'))
You can use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'))
to convert the column in to datetime format.将列转换为日期时间格式。
