Preparation notes for running Selenium ChromeDriver & Python on Mac
selenium-test.py
# coding:utf-8
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from time import sleep
import chromedriver_binary
#Open your browser.
driver = webdriver.Chrome()
#Open the Google search TOP screen.
driver.get("https://www.google.co.jp/")
#Type "selenium" as the search term and press Enter.
search = driver.find_element_by_name('q')
search.send_keys("selenium automation")
search.send_keys(Keys.ENTER)
#The title is "Selenium-Click the link that matches "Web Browser Automation".
#element = driver.find_element_by_partial_link_text("SeleniumHQ Browser Automation")
#element = driver.find_element_by_link_text("WebDriver")
element = driver.find_element_by_partial_link_text("Selenium")
element.click()
#Wait for 5 seconds.
sleep(5)
#Quit the browser.
driver.close()
Execute
$ python3 selenium-test.py
It is OK if the browser closes after 5 seconds after automatically transitioning from google to the selenium page

I installed the Chrome driver while checking the version, but it was not used correctly. Import and solve
import chromedriver_binary
Once installed, you may want to add /usr/local/lib/python3.7/site-packages/chromedriver_binary/ to your PATH or import chromedriver_binary at the beginning of your Python script.

It seems that I could not find the search window below, so
driver.find_element_by_id("lst-ib").send_keys("selenium")
Replace with the following to solve
search = driver.find_element_by_name('q')
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"link text","selector":"SeleniumHQ Browser Automation"}
Traceback (most recent call last):

It seems that I could not search for "Selenium HQ Browser Automation" in the following part, so
element = driver.find_element_by_partial_link_text("SeleniumHQ Browser Automation")
This time, find_element_by_partial_link_text ("Selenium") is used for partial search to solve the problem.
element = driver.find_element_by_partial_link_text("Selenium")
