Pandas DataFrame sort_values()

import pandas as pd 
my_dict={'NAME':['Ravi','Raju','Alex','Ron','King','Jack'],
         'ID':[1,2,3,4,5,6],
         'MATH':[80,40,70,70,70,30],
         'ENGLISH':[80,70,40,50,60,30]}
my_data = pd.DataFrame(data=my_dict)
print(my_data.sort_values(by=['MATH']))

   NAME  ID  MATH  ENGLISH
5  Jack   6    30       30
1  Raju   2    40       70
2  Alex   3    70       40
3   Ron   4    70       50
4  King   5    70       60
0  Ravi   1    80       80

Using two columns

print(my_data.sort_values(by=['MATH','ENGLISH']))

   NAME  ID  MATH  ENGLISH
5  Jack   6    30       30
1  Raju   2    40       70

4  King   5    70       60
0  Ravi   1    80       80

print(my_data.sort_values(by=['MATH'],ascending=False))

   NAME  ID  MATH  ENGLISH
0  Ravi   1    80       80
2  Alex   3    70       40
3   Ron   4    70       50
