            Consider a string blessing = 'Stay Happy n Healthy'. For each of the five rows of the following table,
            write the appropriate slicing statement in the space provided in the table that produces the output given in the
            second column.

            Ans.
                      Verified Command

                  blessing[:6]
                  blessing[2:10:4]
                  blessing[3:10]
                  blessing[-1::-1]
                  blessing[-3:-12:-2]

            Program 25

            Consider the following strings:

            Ans. code1 = 'Stay Safe'
                 code2 = 'stay alert and stay safe'
                 code3 = 'STAY AWARE'

                 code4 = '999999999'
                 code5 = 'Call@999'
                 code6 = 'Call999'
                 code7 = '  '

                 code8 = '  Be ethical   '
                 code9 = 'safetyfirst'
            For each of the commands given in the second column of the table given below, write the output in the third column
            that will be produced on the execution of the statements (in the second column) by Python interpreter.
