Answer :-

a =

print(Sales.T.append(Sales2.T).T)

b =

print(Sales.T)

c =

print(Sales['2017'])

d =

print(Sales['2017']['Madhu'])
print(Sales['2018']['Madhu'])
print(Sales['2017'][‘ Ankit’])
print(Sales['2018'][“ Ankit”])

e =

print(Sales['2017'][‘ Shruti’])

g =

del  Sales['2014']

h =

Sales=Sales.drop('Kinshuk', axis=0)]

i =

Sales.rename({'Ankit':'vivaan','Madhu':'Shailesh'}, axis='index')

j =

Sales['2018']['Shailesh']= 100000

k =

Sales.to_csv( 'e:/SalesFigures.csv', sep = ',', header = False, index= False)

l =

SalesRetrieved  = pd.read_csv('e:/SalesFigures.csv',sep =",",names=['2014',  '2015',  '2016',  '2017'])
SalesRetrieved.index=['Shailesh','Kusum','Kinshuk','vivaan','shruti']
