Your requirement is contradicting the data in your Excel sheet. One problem I can find is that you are now clearing the list after each row ..

    for i in range(2, sheet.nrows):
        sheetinlist = sheet.row_values(i)
        rowdata[:] = []
        for cell in sheetinlist:
                    if cell is not '':
                            rowdata.append(cell)
        print rowData
