Python crawls the data and gets a list, but how to remove the span tag in it?

Question

I used p6ython3.6 to crawl down some data, but what was finally displayed was a list containing span tags. When I used get_text, contents, etc., an error would be reported. Why is this?
The initial results returned are as follows:

[<span>2017.5.2</span>]
[<span>2017.4.26</span>]
[<span>2017.4.24</span>]
[<span>2017.4.19</span>]
[<span>2017.3.23</span>]
[<span>2017.3.17</span>]
[<span>2017.2.14</span>]
[<span>2017.2.9</span>]
[<span>2017.2.6</span>]
[<span>2017.2.6</span>]

My code is as follows:

import requests
from bs4 import BeautifulSoup
import re

# def url_list():
#     for number in range(1,21):
#         url_links=[]
#         url="X".format(i=number)
#         url_links.append(url)

h={"User-Agent":"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.81 Safari/537.36"}
r=requests.get("url",headers=h)
soup=BeautifulSoup(r.text,'lxml')

for data in soup.find("p",{"class":"list-main-eventset-finan"}).find_all("li"):
    content=data.find("i",{"class":"cell date"}).find_all("span")
    print(time)

Answer 1

I don’t remember the API of bs very clearly. There should be a function that can directly obtain the text. It should be get_text()这个函数吧。由于你用的是find_all(). Then I need to traverse the returned result again, that’s it

rs = list()
for data in soup.find("p",{"class":"list-main-eventset-finan"}).find_all("li"):
    contents=data.find("i",{"class":"cell date"}).find_all("span")
    for content in contents:
        rs.append(content.get_text())
  

In addition, you can also use regular expressions to match directly <span>(.*?)<this pattern. But you have to traverse the contens list as above.

Answer 2

The questioner can try the text_content() method

Answer 3

Regular expressions or split+SUBSTRING can also be used, use them flexibly
