BeautifulSoup Absoute URLs Print to CSV - python-3.x

Question

I've been going through tons of threads on here to see if I can find a way to fix this code but cant quite seem to get this to work. I'm trying to scrape links from a site then write to csv. Here's the code:
I found a way to get 95% of the way there but am missing something for getting just the href:
from bs4 import BeautifulSoup
import urllib.request
import urllib.parse
import csv
j = urllib.request.urlopen("http://cnn.com")
soup = BeautifulSoup(j, "lxml")
data = soup.find_all('a', href=True)
for url in soup.find_all('a', href=True):
#print(url.get('href'))
with open('marcel.csv', 'w', newline='') as csvfile:
write = csv.writer(csvfile)
write.writerows(data)

Answer 1

Here is probably what you want to do.
from bs4 import BeautifulSoup
import requests #better than urllib
import csv
j = requests.get("http://cnn.com").content
soup = BeautifulSoup(j, "lxml")
data = []
for url in soup.find_all('a', href=True):
print(url['href'])
data.append(url['href'])
print(data)
with open("marcel.csv",'w') as csvfile:
write = csv.writer(csvfile, delimiter = ' ')
write.writerows(data)

I use openpyxl to get it
from openpyxl import Workbook,load_workbook
I think it is very easy.
it is a part of my project,you could try it
def createExcel(self):
wb = Workbook(optimized_write=True)
ws = wb.create_sheet(title='书籍列表')
row0 = ['编号','条码号','题名','责任者','借阅日期','归还日期','馆藏地']
ws.append(row0)
save_path = 'book_hist.xlsx'
wb.save(save_path)
def saveToExcel(self,data_list):
wb = load_workbook(filename='book_hist.xlsx')
ws = wb.get_sheet_by_name('书籍列表')
for i in range(len(data_list)):
ws.append(data_list[i])
save_path = 'book_hist.xlsx'
wb.save(save_path)
