我使用requests和beautiful soup提取一些wikipedia数据，然后我想将其放入pandas数据框（所有单元格的列名为column1）。我在尝试调用 Dataframe 时遇到此错误：
valueerror:未正确调用 Dataframe 构造函数！
有人有什么建议吗？这是我的密码：
import pandas as pd
import requests
import bs4
result = requests.get("https://en.wikipedia.org/wiki/United_States")
# Put the data into BS
soup = bs4.BeautifulSoup(result.text,"lxml")
# select any soup element
soup.select('p')
# take the result from the list element
Results = soup.select('p')[2].getText()
# print to csv
df = pd.DataFrame(Results, columns=['Column1'])
print(df)

结果是一个文本字符串：
你可以使用
io```pd.DataFrame(io.StringIO(Results), columns=['Column1'])
pd.DataFrame([Results], columns=['Column1'])
Column1
