Answer 1

From what I see you have an error in line 7 as it's pointed out in the traceback.

In the line of code you define your path you're trying to use an absolute path.

PATH ="/Users/kaikeichan/Desktop/python_webpage/chromedriver"

The problem in here may be that you are not writing the right path to the chromedriver file. Your path should have a C: before user (that is if you have your project stored in your computer and not an external hard drive or something similar) like this:

 PATH ="C:/Users/kaikeichan/Desktop/python_webpage/chromedriver"

Another thing you could try is adding a ".exe" in the end of chromdriver as it is a .exe file and you should specify that.

 PATH ="C:/Users/kaikeichan/Desktop/python_webpage/chromedriver.exe"

I really hope this helps and I would suggest you try to use a relative path because it could be simpler to you. If your ".py" python file is in the same folder your chromdriver file is allocated then you could just define the path as "chromedriver.exe" and that would be an effective use of a relative path.
