from bs4 import BeautifulSoup
import requests


r = requests.get(
    "http://www.federalreserve.gov/econresdata/researchdata/feds200628_1.html")
soup = BeautifulSoup(r.content)

 # column headers
 h = data.find_all("th", scope="col")
 # get all the tr tags after the headers
 final = [[t.th.text] + [ele.text for ele in t.find_all("td")] for t in h[-1].find_all_next("tr")]
 headers = [th.text for th in h]

The final out list is all the rows in individual lists:

Answer 2

There are a lot of issues in your code.

1. There is no table with class 'tablestats'.
2. There are no 'th' fields with class 'header'.

3. Following line-

   table_items = [(a.text, b.text) for ele in data for a, b in [ele.find_all("td")]]

doesnt return just 2 values, so cant assign to a, b
