Unable to display website on chrome when ran the program

I had recently started learning automation with python using selenium. I had installed chromedriver but when i run the code chrome displays no output. My code:
from selenium import webdriver
PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)
driver.get("www.wikipedia.com")
Output
Output :
C:\Users\Admin\PycharmProjects\untitled\venv\Scripts\python.exe C:/Users/Admin/PycharmProjects/untitled/1.py
Traceback (most recent call last):

Please help as I'm unable to proceed.
Thanks!

URL should contain scheme. Simply replace
"www.wikipedia.com"
with
"https://www.wikipedia.com"

Unable to store a function in a variable in Selenium

Okay so I was writing my first selenium code which is:
browser.get('https://www.jetbrains.com/pycharm/')
browser.find_element_by_link_text('Download')
<selenium.webdriver.remote.webelement.WebElement (session="69f43bf4a5e98baf24ad3746dd01b514", element="0fa96685-d871-464f-aaaa-af02238a5f08")>
I wanted to simply go to the pycharm website and click on downloads, which worked fine.
But when I tried to store the previous function in a variable like so:
elem = browser.find_element_by_link_text('Download')
I got all these errors:
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "C:\Users\admin\AppData\Local\Programs\Python\Python37-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 428, in find_element_by_link_text

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.NoSuchWindowException: Message: no such window: window was already closed
(Session info: chrome=87.0.4280.66)
I have no idea what they mean or what ive done wrong. Help much appreciated.
PS: I am using pycharm and selenium chromedriver if thats helpful.

No issues in this.
from selenium import webdriver
browser = webdriver.Chrome(executable_path='C:/bin/chromedriver.exe')
browser.get('https://www.jetbrains.com/pycharm/')
element = browser.find_element_by_link_text('Download')
element.click()

Python Selenium-Debug a Simple Code with YouTube

I followed this tutorial for Selenium with Python:
So I did the same as the tutorial:
from selenium import webdriver
driver=webdriver.Chrome()
driver.get('https://www.youtube.com/')
searchbox = driver.find_element_by_xpath('//*[#id="search-input"]')
searchbox.send_keys('cooking')
But I get this error:
Traceback (most recent call last):
File "C:/ANGUS/DATA_ANALYSIS/WEBSCRAPING/TextXXX.py", line 7, in <module>
searchbox.send_keys('cooking')
File "C:\Users\Angus\PycharmProjects\Test\venv\lib\site-packages\selenium\webdriver\remote\webelement.py", line 477, in send_keys
self._execute(Command.SEND_KEYS_TO_ELEMENT,
File "C:\Users\Angus\PycharmProjects\Test\venv\lib\site-packages\selenium\webdriver\remote\webelement.py", line 633, in _execute
return self._parent.execute(command, params)
File "C:\Users\Angus\PycharmProjects\Test\venv\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
self.error_handler.check_response(response)
File "C:\Users\Angus\PycharmProjects\Test\venv\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.ElementNotInteractableException: Message: element not interactable
(Session info: chrome=81.0.4044.138)
How can I fix this?

Another way to do that in order not to use the search is by inserting the query itself.
Code:
your_query = "cooking"
driver.get("https://www.youtube.com/results?search_query=" + str(your_query))
time.sleep(5)
In this way, it is like you are going immediately in the output that you want after searching a specific query of yours. So, let's say that instead of typing cooking, you can .get() to the URL you want by adding your query into this URL.

Encountering selenium.common.exceptions.WebDriverException only on specific web page

I'm trying to create a content scraper to gather a list of medical terms and I'm using https://www.merriam-webster.com/browse/medical for that task. All I have in my code right now is:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("https://www.merriam-webster.com/browse/medical/a")
driver.close()
The following error message is shown after every run of the program using this or any https://www.merriam-webster.com URL:
Traceback (most recent call last):
File "mw-download.py", line 5, in <module>
driver.get("https://www.merriam-webster.com/browse/medical/a")

self.execute(Command.GET, {'url': url})
File "/usr/local/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 256, in execute
self.error_handler.check_response(response)
File "/usr/local/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: Reached error page: about:neterror?e=dnsNotFound&u=https%3A//nop.xpanama.net/if.html%3Fadflag%3D1%26cb%3DKHg6C73w9F&c=UTF-8&f=regular&d=Firefox%20can%E2%80%99t%20find%20the%20server%20at%20nop.xpanama.net.
I have tried changing the URL to different sites, with and without https support to test if it was something with https, but I haven't encountered this error with any other site. I also tried removing the driver.close() command at the end of the script to see if trying to close the driver before the page contents were loaded is what was causing the problem but the problem persists even without that line of code.
Any help in understanding this error and fixing it would be greatly appreciated!

It looks like you've got a problem with your file encoding. I'm not sure if that's the BOM or not, but you should check your file with a hex editor.
