Color formatting excel file row in python

I have dataframe where I have 2 Date columns. I have to compare them and if they are different then whole row should be colored. Please check the picture.

Please guide me how can I do that in python. Thanks in advance.

Answer

Create styles in helper DataFrame and export to excel:

df = pd.DataFrame({'Date1':['19/3/2011','15/5/2015','18/8/2018'],
                   'Date2':['19/3/2011','1/1/2019','18/8/2018']})

print (df)
       Date1      Date2
0  19/3/2011  19/3/2011
1  15/5/2015   1/1/2019
2  18/8/2018  18/8/2018

def highlight_diff(x): 
   c1 = 'background-color: red'
   c2 = '' 
   m = x['Date1'] != x['Date2']

   df1 = pd.DataFrame(c2, index=x.index, columns=x.columns)
   df1.loc[m, :] = c1
   return df1

(df.style
   .apply(highlight_diff,axis=None)
   .to_excel('styled.xlsx', engine='openpyxl', index=False))
