I have an Excel workbook that I have already loaded and put all the sheets together, now I would like to add a column where I have the name of each original sheet, I don't know if I have to do it before I put everything together, and if that's how I could do it , I am using pandas. This is my code so far, I want the sheet name or number to be in the "Week" column.
xlsx= pd.ExcelFile('archivo.xlsx')
hojas=[]
for hojaslibro in xlsx.sheet_names:
hojas.append(xlsx.parse(hojaslibro))
estado=pd.concat(hojas,ignore_index=True)
estado['Week']=0
estado.Week = <all_sheet_names_list>?
