Trouble Extracting Review from Yelp

Question

Started web scraping and I've been trying to get the rating off this yelp review.

my code:

rating = review.find('img', attrs={'class': 'offscreen__373c0__1KofL'}).get('alt')

rating = float(re.findall('\d+', rating)[0])

print(rating)

result:

Traceback (most recent call last):
  File "/Users/joseochoa/PycharmProjects/webbscraper/Tutorial_scraper.py", line 40, in <module>
    rating = float(re.findall('\d+', rating)[0])
IndexError: list index out of range

Any help or suggestions would be appreciated. Thank you.

Answer 1

It seems that re.findall('\d+', rating) returns empty list.
For this reason when you try to get the first element of the list you have this error.

You can modify your code like this:

rating = review.find('img', attrs={'class': 'offscreen__373c0__1KofL'}).get('alt')
rating_list = re.findall('\d+', rating)

if len(rating_list) > 0:
   rating_float = float(rating_list[0])
   print(rating_float)
else:
   print("No matches have been found")
   # manage with specific actions if you want
