Python: TypeError: must be str, not bytes

Question

I was trying to write the code for processing an html webpage and create an excel sheet out of it. There is the error throwing up. Please let me know if anyone can help. A lot of code which i ran is commented. I wanted to include that too.

book = xlwt.Workbook(encoding="utf-8")
sheet1 = book.add_sheet("Product List")

i=0
for row in soup.findAll('li', { "class" : "product-link" }):
    link = row.a['href']
    #print(link)
    #print(link[23:])

    conn = http.client.HTTPSConnection("www.sanjamar.com")
    conn.request("GET", link[23:])
    req = conn.getresponse()
    #print(req.status, req.reason) 
    data2 = req.read()
    soup2=BeautifulSoup(data2)

    Name=soup2.find('title')
    Name_text = Name.text
    words = Name_text.split('|')
    Name = words[0]
    print(Name)

    if len(soup2.find_all("div", {"id":"productDescription"})) > 0:
        Desc = soup2.find('div', {"id":"productDescription"})
        ProdDesc = Desc.p
        #print(ProdDesc)

        if ProdDesc != None:
            Desc == ProdDesc.text

    if len(soup2.find_all("div", {"id":"productBenefits"})) > 0:
        Feat = soup2.find('div',{"id":"productBenefits"})
        ProdFeat = Feat.ul
        #print(ProdFeat)

        if ProdFeat != None:
            Feat == ProdFeat.text

    if len(soup2.find_all("table", {"class":"mceItemTable"})) > 0:
        Spec = soup2.find('table',{"class":"mceItemTable"})
        #print(Spec)
        if Spec != None:
            specrow = ''
            for row in Spec.findAll('tr'):
                specrow = specrow + ',' + row.text

        if specrow != None:
            Spec = specrow[1:]

        words = Spec.partition(",")[2]        


    record = (Name,Desc.text,Feat.text[20:],words)
    print(record)

        sheet1.write(i, col_index, item)
    i += 1
