使用字符串制作熊猫数据框

Question

大家好，

我尝试将数据框列设为“日期”并将日期时间添加到列行。日期时间在字符串列表中每 5 次出现一次。

我认为像 range(start,end,step) 这样的方法会很好，但在实践中如何实现呢？

这是我的代码：

import requests, re, pandas
from bs4 import BeautifulSoup

r=requests.get("http://www.hltv.org/?pageid=188&statsfilter=2816&offset=0")
c=r.content

soup=BeautifulSoup(c,"html.parser")


for string in soup.find_all("div",{"class":"covSmallHeadline"})[6:]:
    print(string.text.replace("(","").replace(")",""))

这是输出（实际列表大小更大）：

5/3 17
 Astralis 16
 FaZe 13
inferno
IEM Katowice 2017
5/3 17
 Astralis 16
 FaZe 12

先将数据转成CSV：

import re
In [83]: for row in table.find_all('div', style=re.compile(r'width:606px;height:22px;background-color')):
   ...:      print(row.get_text(strip=True, separator=','))


5/3 17,Astralis (16),FaZe (13),inferno,IEM Katowice 2017
5/3 17,Astralis (16),FaZe (12),nuke,IEM Katowice 2017
5/3 17,Astralis (16),FaZe (12),overpass,IEM Katowice 2017
