How to convert multiple excel sheets to csv python

I want to convert all the excel document(.xls) sheets into csv, If excel document has one sheet only then I am converting like as follow-

   wb = open_workbook(path1)
    sh = wb.sheet_by_name('Sheet1')
    csv_file = open(path2, 'w')
    wr = csv.writer(csv_file, quoting=csv.QUOTE_ALL)
    for rownum in range(sh.nrows):
        wr.writerow(sh.row_values(rownum))
    csv_file.close()

If my excel(.xls) document have more than one sheet i.e.('Sheet1', 'Sheet2', 'Sheet3', 'Sheet4') than how to convert all sheets into csv.

Any help would be appreciated.

Answer

wb.sheet_names() to get all the sheet names, and then loop it and dynamically put the name in the sheet_name
