              21.  Consider the following code:                                                                [2022]
                 import pandas as pd
                 Sl=pd.Series ( [23,24,35,56], index= [ 'a', 'b', 'c',d'])
                 S2=pd.Series ( [27,12,14,15],
                 index=[ 'b','y' ,'c','ab'])
                 df=pd.DataFrame (S1+S2)
                 print (df)
                  Output for the above code will be:

              22.  Sudhanshu has written the following code to create a DataFrame with boolean index:          [2022]
                 import numpy as np
                 import pandas as pd
                 df=pd.DataFrame (data=[ [5,6,7]],index=[true, false, true])
                 print (df)
                  While executing the code, she is getting an error, help her to rectify the code:
                  a.  df=pd.DataFrame([True,False, True], data=[5,6,7])
                  b.  df=pd.DataFrame(data=[5, 6,7], index=[True, False, True])
                  c.  df=pd.DataFrame([true,false, true],data=[5,6,7])
                  d.  df=pd.DataFrame(index=[true,false, true],data[[5,6,7]])
             Ans.  b. df=pd.DataFrame(data=[5, 6,7], index=[True, False, True])
