如何从 Python 中的日期时间序列中返回单个日期？

Question

I have a datetime column in a data frame. From that column i want to return every single day. In that df, I have 14 days and each day has so many values with even miliseconds.

So I want a output like [2022-07-18, 2022-07-19,………………]

Answer 1

You can standardize the format with .dt.date . If it has not yet been converted into datetime, then use:

df['Dates'] = pd.to_datetime(df['Dates'],infer_datetime_format=True).dt.date

Answer 2

Did you read the official documentation of pandas about this topic? https://pandas.pydata.org/docs/reference/api/pandas.to_datetime.html
