Answers for "do we have to change datetime format from string in dataframe"

convert column to datetime format python

df['Dates'] = pd.to_datetime(df['Dates'], format='%y%m%d') 

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

dtype = pd.SparseDtype(np.dtype('datetime64[ns]'))
series = pd.Series(df.date, dtype=dtype)
df['date']=np.array(series)

apply format to pandas datetime column

formatted_df = df["Date"].dt.strftime("%m/%d/%y")
