import pandas as pd 
my_dict={'NAME':['Ravi','Raju','Alex','Ron','King','Jack'],
         'ID':[1,2,3,4,5,6],'MATH':[30,40,50,60,70,80],
         'ENGLISH':[20,30,40,50,60,70]}
my_data = pd.DataFrame(data=my_dict)
my_data=my_data.add_suffix('_Col')
print(my_data)

  NAME_Col  ID_Col  MATH_Col  ENGLISH_Col
0     Ravi       1        30           20
1     Raju       2        40           30

my_s=pd.Series([1,5,7,9,10])
my_s=my_s.add_suffix('_Ser')
print(my_s)

0_Ser     1
1_Ser     5
