I'm looking at this URL.
https://en.wikipedia.org/wiki/Wikipedia:Unusual_place_names

If I hit F12 I can see tags such as these:
<a title=
<a class=
And so on and so forth.  

I'm wondering if someone can share a script, or a function, that will allow me to pass in variables and download (or simply print) the results.  I saw a sample online that I thought would work, and I made a few modifications but now I keep getting a message that says: ValueError: All objects passed were None

Here's the script that I'm playing around with.

import requests
import pandas as pd
from bs4 import BeautifulSoup

#Get the relevant webpage set the data up for parsing
url = "https://en.wikipedia.org/wiki/Wikipedia:Unusual_place_names"
r = requests.get(url)
soup=BeautifulSoup(r.content,"lxml")

#set up a function to parse the "soup" for each category of information and put it in a DataFrame
def get_match_info(soup,tag,class_name):
    info_array=[]
    for info in soup.find_all('%s'%tag,attrs={'class':'%s'%class_name}):
        return pd.DataFrame(info_array)

#for each category pass the above function the relevant information i.e. tag names
tag1 = get_match_info(soup,"td","title")
tag2 = get_match_info(soup,"td","class")

#Concatenate the DataFrames to present a final table of all the above info 
match_info = pd.concat([tag1,tag2],ignore_index=False,axis=1)

print match_info

I'd greatly appreciate any help with this.
