Python Pandas无法打印使用Jupyter笔记本中的xpath从web收集的对象列表

这是我使用的代码。我使用的是Jupternotebook网络版。我升级了XML，python版本是3.8

import numpy as np
import requests 
from lxml import html
import csv
import pandas as pd

# getting the web content

r = requests.get('http://www.pro-football-reference.com/years/2017/draft.htm')
data = html.fromstring(r.text)

收集具体数据

pick = data.xpath('//td[@data_stat="draft_pick"]//text()')
player = data.xpath('//td[@data_stat="player"]//text()')
position = data.xpath('//td[@data_stat="pos"]//text()')
age= data.xpath('//td[@data_stat="age"]//text()')
games_played = data.xpath('//td[@data_stat="g"]//text()')
cmp = data.xpath('//td[@data_stat="pass_cmp"]//text()')
att = data.xpath('//td[@data_stat="pass_att"]//text()')
college = data.xpath('//td[@data_stat="college_id"]//text()')

data = list(zip(pick,player,position,age,games_played,cmp,att,college))

df = pd.DataFrame(data)
df

在我尝试的两个单独的文件上显示了两个错误：

AttributeError:“list”对象没有属性“xpath”

---

代码没有提供我想要的网页数据列表。有人能帮我解决这个问题吗？提前感谢。

您可以使用

read\u html

将html表格直接加载到数据框中：

import pandas as pd

df = pd.read_html('http://www.pro-football-reference.com/years/2017/draft.htm')[0]
df.columns = df.columns.droplevel(0) # drop top header row
df = df[df['Rnd'].ne('Rnd')] # remove mid-table header rows 

输出：
