The python xlrd operating the EXCEL (a)

import xlrd  

# Open the Excel file to read the data 
filename = r'C: \ Users \ Administrator \ Desktop \ services company payroll water table \ TransferSample.xls' 
the Data = xlrd.open_workbook (filename) 
# Gets Book in a worksheet 
# table = data .sheets () [0] # through index order 
# acquired by name = data.sheet_by_name Table # ( 'name') 
Table data.sheet_by_index = (0) 


# line operation 
nrows = table.nrows # effective in obtaining the sheet rows 
table.row (0) # returns a list of all the cells in the row of objects 
table.row_slice (0) # returns a list of all the columns of the cell objects 
table.row_types (0, start_colx = 0, end_colx = None) # returns a list of the data types of all the cells in the row composition 
table.row_values (0, start_colx = 0, end_colx = None) # returns a list of all the data cells in that row composition 
table .row_len (0) # returns the effective column length of the cell 


operation # column 
the effective number of columns ncols = table.ncols # Get list
table.col (0, start_rowx = 0, end_rowx = None) # returns a list of all the columns of the cell objects 
table.col_slice (0, start_rowx = 0, end_rowx = None) # returns all of the column cell object list consisting 
table.col_types (0, start_rowx = 0, end_rowx = None) # returns a list of the data types of all the cells in the column consisting of 
table.col_values (0, start_rowx = 0, end_rowx = None) # this returns a list of all the data cells in that column composition 


# cell operation 
table.cell (0,0) # returns the cell object 
table.cell_type (0,0) # return data type in the cell 
table.cell_value (0,1) # returns the data in the cell

When you open a file and open the sheet tab, try to catch wrong:

filename = r'C: \ Users \ Administrator \ Desktop \ payroll services company flow table \ TransferSample.xlsx ' 
the try: 
    Data xlrd.open_workbook = (filename) 
the except FileNotFoundError AS E: 
    Print (f'Error: {E} \ n-. Please check the file path is correct ')? 

the try: 
    # = Table data.sheet_by_index (. 3) 
    Table data.sheet_by_name = (R & lt' first page ') 
the except IndexError AS E: 
    Print (' Error:. {} \ n-opened sheet fails, check sheet if there is? '. format (e))
