Python Pandas Conversion of days

Question

I am trying to change string to a datetime64[ns] format in format days.month.year, but I get this error:

ValueError: time data '01.02.2016' does not match format '%dd.%mm.%YYYY' (match)

df['Start Date 2']= pd.to_datetime(df['Start Date'], format = "%dd.%mm.%YYYY")

Or Can I somehow modify this code? To have desired output in format of days.month.year?

df['Start Date 1']=df['Start Date'].astype('datetime64[ns]')

This is how the input values look like: '01.02.2016' it is in format days.months.years

I want the output look like this but being a datetime64[ns] format

Answer 1

This is the correct format:

df['Start Date 2']= pd.to_datetime(df['Start Date'], format = '%d.%m.%Y')
