use range , format

for in range(1,5):     contenta = tree.xpath("//table[@class='yfnc_tabledata1']/tr[1]/td/table/tr[2]/td[{i}]".format(i=i))[0].text_content().strip()     print(contenta)

output

total revenue 31,821,000 30,871,000 29,904,000 
for in range(1,5):     contentb = tree.xpath("//table[@class='yfnc_tabledata1']/tr[1]/td/table/tr[3]/td[{i}]".format(i=i))[0].text_content().strip()     print(contentb)

output

cost of revenue 16,447,000 16,106,000 15,685,000

edit

in [22]: d = {}  in [23]: d.setdefault('revenue', []) out[23]: []  in [24]: in range(2,5):    ....:     contentb = tree.xpath("//table[@class='yfnc_tabledata1']/tr[1]/td/table/tr[3]/td[{i}]".format(i=i))[0].text_content().strip()    ....:     d['revenue'].append(int(contentb.replace(',', '')))    ....:       in [25]: d out[25]: {'revenue': [16447000, 16106000, 15685000]}
