Removing timestamp from a column name in a pandas dataframe

Question

I have the following dataframe:

    ID  2019-01-31 00:00:00
 0  R01 1

How can I remove the time from the column name, so that I can slice the df by df['31/01/2019']?

Answer 1

You can do something like that:

from datetime import datetime

df.columns = [i.strftime('%Y-%m-%d') if isinstance(i, datetime) else i for i in df.columns]
