以下の Selenium3での内容の修正点が多すぎなのでメモを残しておく
Windows 10 + Python3 + selenium + msedgedriver で headless edge(Chromium) を試してみる
Windows 10 + Python3 + selenium + chromedriver で headless chrome を試してみる
※BeautifulSoupは整形されたhtmlの出力用に使用している

モジュールのインストール

pip install -U selenium
pip install webdriver_manager 

サンプルコード

PS > python -V
Python 3.10.5

Chrome版

# Windows Add env PYTHONIOENCODING = UTF-8 & restart vscode
# coding:utf-8

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from bs4 import BeautifulSoup

options = Options()
options.add_argument('--headless')

# ダウンロードしたWebDriverのパスを直接記述する場合
# svc = Service('C:\\Dev\\tool\\webdriver\\chromedriver.exe')

svc = Service(ChromeDriverManager().install())
# [WDM] - ====== WebDriver manager ======

driver = webdriver.Chrome(service=svc, options=options)

# yahoo newsにアクセス
driver.get('https://news.yahoo.co.jp/')

# htmlを取得・表示
html = driver.page_source

# 整形されたソースを表示するため
soup = BeautifulSoup(html, 'html.parser')
print(soup.prettify())

# print(html)

# ブラウザーを終了
driver.quit()

Edge版

from selenium.webdriver.edge.service import Service
from selenium.webdriver.edge.options import Options

options = Options()
options.add_argument('headless')
