I have a datestring in thew following format which is month/day/year and then time

print(df):
Date
6/06/20 4:41pm
6/06/20 5:41pm

I am trying to convert using pd.to_datetime and have used the following:

df['Date'] =  pd.to_datetime(df['Date'], format='%m%d%Y:%H:%M.%f')

but I cant match the format. Does anyone know the format for this particular sting? thank you very much!

Thanks so much. as a follow up question. If I wanted to filter only rows for today how would I do that? I have tried today = date.today() and tomorrow = today + timedelta(days=1) and then df= df[[df['Date']<tomorrow]] but getting an TypeError: Invalid comparison between dtype=datetime64[ns] and date error
Based on your latest comment. If wanted to select todays date df.assign(Dates=pd.to_datetime(df['Date']).dt.date)==pd.Timestamp('today')#Boolean selection df[df.assign(Dates=pd.to_datetime(df['Date']).dt.date)==pd.Timestamp('today')].dropna()#DataFrame

you are missing part of the format

df['Date'] =  pd.to_datetime(df['Date'], format='%m/%d/%Y %H:%M.%f')
