Web Scraping shopee.sg with selenium and BeautifulSoup in python

The issue was that the products that you were trying to scrape load dynamically as you scroll down the page. There may be more elegant solutions than mine, but I implemented a simple javascript scroller, using driver.execute_script (additional resource: https://www.geeksforgeeks.org/execute_script-driver-method-selenium-python)

Scroller

which scrolls to a tenth of the page's height, pauses for 500 milliseconds, and then continues.

driver.execute_script("""
    var scroll = document.body.scrollHeight / 10;
    var i = 0;
    function scrollit(i) {
       window.scrollBy({top: scroll, left: 0, behavior: 'smooth'});
       i++;
       if (i < 10) {
           setTimeout(scrollit, 500, i);
       }
    }
    scrollit(i);
""")

Additionally, you had two for loops, for item_n in soup.find_all(...), for item_c in soup.find_all(...) that were iterating over divs in the same class. I fixed that, in my code, so that you can get both the price and the name of each item while only using one for loop.

You also had try-except statements (in case there was an AttributeError, i.e. if the items you were finding in soup.find_all were NoneTypes). I simplified those into if statements, like this one

name = item.find('div', {'class': 'yQmmFK _1POlWt _36CEnF'})
if name is not None:
    name = name.text.strip()
else:
    name = ''

And finally, you were using zip for two different lists (names and prices), to add to a csv file. I combined those individual lists into a nested list in the for loop, instead of appending to two separate lists and zipping at the end. This saves a step, though it is optional and may not be what you need.
