"I'm Feeling Lucky" script problem (again)
#1
I didn't get any replies to the other related thread; and, because one other person in that thread had the same problem as me with no answers I thought it appropriate to start a new thread.

Original question:

"Man, I'm having trouble with this project too. I'm getting no search results after passing the search terms into the run window."

My script returns this output:
"Googling...
None
Press any key to continue . . ."

My script:
#! python3
# lucky.py - Opens several Google search results.
 
import webbrowser, bs4, requests, sys
 
print('Googling...') # display text while downloading the Google page
res = requests.get('http://google.com/search?q=' + ' '.join(sys.argv[1:]))
print(res.raise_for_status())
 
# Retreive top search result links.
soup = bs4.BeautifulSoup(res.text, "html.parser")
 
# Open a browser tab for each result
linkElems = soup.select('.r a')
numOpen = min(5, len(linkElems))
for i in range(numOpen):
    webbrowser.open('http://google.com' + linkElems[i].get('href'))

print(linkElems)

If you look at the response you're getting, there are no links nested under a .r class. The page that google sends you is dependent upon whether or not you have javascript enabled. So, inspect what you're getting, and narrow your selector appropriately.

Hmmm. Wall

When I inspect the page I do see a .r
<div class="r"><a href="https://www.python.org/" for each link listed in the search: "python."

I added that code you posted to lines 19-20 of my script and I got the output:
Googling...
None
[]
Press any key to continue . . .

I tried just eliminating the .r class and I got the 5 browsers to open, but predictably I just got the first 5 links under the a class.

I checked in my Chrome settings and javascript was enabled

Thanks!!

Look at Web-scraping part-2,under "God dammit JavaScript, why do i not get all content".
I have done this task before look at hint on this line browser.page_source.
soup = BeautifulSoup(browser.page_source, 'lxml')
If do like this will get JavaScript(how in it look Browser) and can parse out links from Google as the look when inspect in browser.

I don't get why the script given to the readers in the Automate the Boring Stuff just doesn't work and why the author hasn't tried to provide additional guidance? I appreciate your help help here. I'm frustrated that I'm still having problems. Ugh.

I get this message when I try to run the script with Selenium in it... This is the script from the "God dammit Javascript..." I tried to figure out how to add the Selenium piece and the browser.page_source to my script and got a similar message.

Quote: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/...river/home
You most have chromedriver.exe in your Windows Path.
Also in Environment Variables Path i have C:\cmder\bin.

Test code.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
import time

#--| Setup
chrome_options = Options()
#chrome_options.add_argument("--headless")
browser = webdriver.Chrome(executable_path=r'C:\cmder\bin\chromedriver.exe')
#--| Parse or automation
browser.get('https://duckduckgo.com')
input_field = browser.find_elements_by_css_selector('#search_form_input_homepage')
input_field[0].send_keys('car' + Keys.RETURN)
time.sleep(3)
images_link = browser.find_elements_by_link_text('Images') # Or name your country use
images_link[0].click()
time.sleep(5)
browser.quit()

Bummer. I don't have admin rights to add this .exe to my PATH. I may just skip this project and move on to the next one. Thanks for your help on this one!

An other solution that work is to have chrome driver an python script in same folder.
browser = webdriver.Chrome(executable_path=r'chromedriver.exe')
