输出beautifulsoup数据到CSV

Question

我想我的输出数据beautifulsoup与2列的CSV：1.标题，背景

所以标题栏应该有soup.Title然后描述应该是print语句是在与开始在courselinks X环......

**#This is what I tried:** 
with open('newcsv.csv','wb') as f: 
    writer = csv.writer(f, delimiter='\t') 
    writer.writerow('Title') 

for x in courselinks[0:3]: 
    data = requests.get(("http:"+x) 
    soup = bs(data.text) 
    print soup.title #This I want in the Title column 
    for header in soup.find_all(text='Description'): 
     nextNode = header.parent 
     while True: 
      nextNode = nextNode.nextSibling 
      if nextNode is None: 
       break 
      if isinstance(nextNode, Tag): 
       print (nextNode.get_text(strip=True).strip().encode('utf-8')) **#This I want in the Description column** 
      if isinstance(nextNode, NavigableString): 
       print (nextNode.strip().encode('utf-8')) **#This I want in the Description column** 
      if isinstance(nextNode, Tag): 
       if nextNode.name == "h2": 
        break 

这就是我想要的......

当写一行到CSV，你只是写数组或列表中的文件。列表或数组中的每个值都是该行中的一个值。如果你想在第一列中的数组中的第一个项目，你把它放在第一位，0索引。该行中的每个后续项目都是数组/列表中的后续索引。

for x in courselinks[0:3]: 
    data = requests.get(("http:"+x) 
    soup = bs(data.text) 
    current_row = [soup.title,''] #This I want in the Title column 
    for header in soup.find_all(text='Description'): 
     current_row[1] = '' 
     nextNode = header.parent 
     while True: 
      nextNode = nextNode.nextSibling 
      if nextNode is None: 
       writer.writerow(current_row) 
       break 
      if isinstance(nextNode, Tag): 
       current_row[1] += nextNode.get_text(strip=True).strip().encode('utf-8') **#This I want in the Description column** 
      if isinstance(nextNode, NavigableString): 
       current_row[1] += nextNode.strip().encode('utf-8') **#This I want in the Description column** 
      if isinstance(nextNode, Tag): 
       if nextNode.name == "h2": 
        writer.writerow(current_row) 
        break
