为什么编写爬虫,idle什么也不运行,也不报错呢?
如题,代码完全照视频或作业答案,同时也照书上代码打了,都无法运行。。。 为啥不放代码?谁知道你在说啥?问问题养成贴代码的习惯,否则和纸上谈兵没什么区别

from bs4 import BeautifulSoup
def main():
url = "http://baike.baidu.com/view/284853.htm"
headers = {'User-Agent': 'Firefox'} # 得改header防反扒
req = request.Request(url, headers=headers)
r = request.urlopen(req)
html = r.read().decode('utf-8')
soup = BeautifulSoup(html, "html.parser")
for each in soup.find_all(href=re.compile("view")):
print(each.text, "->", ''.join(["http://baike.baidu.com", each["href"]]))
