Truncate `TimeStamp` column to hour precision in pandas `DataFrame`

Question

I have a pandas.DataFrame called df which has an automatically generated index, with a column dt:

df[\'dt\'].dtype, df         


        

Answer 1

A method I've used in the past to accomplish this goal was the following (quite similar to what you're already doing, but thought I'd throw it out there anyway):

df['dt2'] = df['dt'].apply(lambda x: x.replace(minute=0, second=0))
