I have one column in I don\'t understand how but there is two different format in a single column.
df[\'Date\'] = [6/24/2019,6/14/2019,2019-09-06 00:00:00,6/
import pandas as pd
df = pd.DataFrame()
df['Date'] = ['6/24/2019','6/14/2019','2019-09-06 00:00:00','6/14/2019','6/14/2019']
df['newDate'] = pd.to_datetime(df['Date'])
print (df)
Date newDate
