How to a pull a specific "data-stat" value? (python)

Question

So the code so far pulls up a page from https://www.basketball-reference.com and grabs any data in tr_body with the data-stat class(???).

I need a way to pull specific values of data stat, for example for https://www.basketball-reference.com/players/l/lowryky01.html output for data-stat="pos" = PG.

from bs4 import BeautifulSoup
import requests

first = ()
first_slice = ()
last = ()


def askname():
    global first
    first = input(str("First Name of Player?"))
    global last
    last = input(str("Last Name of Player?"))
    print("Confirmed, loading up " + first + " " + last)
# asks user for player name

askname()


first_slice_result = (first[:2])
last_slice_result = (last[:5])
print(first_slice_result)
print(last_slice_result)
# slices player's name so it can match the format bref uses
first_slice_resultA = str(first_slice_result)
last_slice_resultA = str(last_slice_result)

first_last_slice = last_slice_resultA + first_slice_resultA

lower = first_last_slice.lower() + "01"

start_letter = (last[:1])
lower_letter = (start_letter.lower())
# grabs the letter bref uses for organization

print(lower)
source = requests.get('https://www.basketball-reference.com/players/' + lower_letter + '/' + lower + '.html').text

soup = BeautifulSoup(source, 'lxml')
tbody = soup.find('tbody')
pergame = tbody.find(class_="full_table")
classrite = pergame.find(class_="right")
tr_body = tbody.find_all('tr')
print(pergame)


# seperates data-stat, apparently you can use .get to get obscure classes
for trb in tr_body:
    print(trb.get('id'))

    th = trb.find('th')
    print(th.get_text())
    print(th.get('data-stat'))


    for td in trb.find_all('td'):
        print(td.get_text())
        print(td.get('data-stat'))

Started this project maybe 4 months ago and I'm having trouble remembering how to split and pull specific data-stats.
