Hey, just passing and I don't really know the code enough to do a PR. Just to let you know I tried your branch and it did not work for me, although the issue is not related with the user agent I think.

twitter_scraper/modules/profile.py

            self.location = None

+        # TODO unfixed
        self.birthday = html.find(".ProfileHeaderCard-birthdateText")[0].text


Not too familiar with the code (and appreciate it's not the issue you are fixing), but I would assume to make the code work it would be better to put this in a try except IndexError block?

Hi, thank you for the response!
The error is an error due to the empty list, I have added an exception catch for all elements, please try again.
I did not use specific IndexError is because the original code did not specify Errors, so I think it will be better to use the same style.

Once again thank you for disclosing the problem!

profile = Profile(f"{user_id}") print(profile.to_dict())

You could try using the code by the fixed version above, I use "BarackObama" as user_id to gets the output below:

output

{'name': 'Barack Obama', 'username': 'BarackObama', 'birthday': None, 'biography': 'Dad, husband, President, citizen.', 'location': 'Washington, DC', 'website': 'obama.org', 'profile_photo': 'https://pbs.twimg.com/profile_images/822547732376207360/5g0FC8XX_normal.jpg', 'banner_photo': None, 'likes_count': None, 'tweets_count': 15921, 'followers_count': 122418592, 'following_count': 601466, 'is_verified': True, 'is_private': False, 'user_id': None}

New version is working! Thanks a lot!

@yeachan153 Thank you too ~ could you please confirm the review request?

@yeachan153 Thank you too ~ could you please confirm the review request?

Seems valid. Could you please merge it? It's been quite a while, everything is better than the current version that is not working with profiles at all.

The last time I checked, the code is working! That's really nice!

I am still a bit concerned about the bare try except blocks; while keeping in the style of the code can give unexpected results in the future. I.e. if the HTML changes, then user attributes can be assigned None without raising an explicit error and could lead to confusing situations and raise cases where mistakes are caught much later because we assume that everything is working as intended.

I am not sure what a perfect solution would be. Maybe errors should be logged even if the scraper continues, so we are aware what went wrong even if the final result is outputted? Just a suggestion.

But nice work on getting everything to work :-)

Thanks for the fix @yimingStar

Seems that soon enough we'd be needing to delegate these properties to a general function because it follows a pattern (find from selector, get first, get text, return value else default to None), and any deviation from that would have to become it's own function.
Generally it's simple and works as it is right now.

I left a suggestion. Let me know what you think.

Suggested change

stats_table = None

stats = None

try:

stats_table = html.find('table.profile-stats')[0]

stats = stats_table.find('td div.statnum')

if not stats:

self.tweets_count = None

self.following_count = None

self.followers_count = None

except:

self.tweets_count = None

self.following_count = None

self.followers_count = None

try:

stats_table = html.find('table.profile-stats')[0]

stats = stats_table.find('td div.statnum')

except:

stats_table = None

stats = None

How about this?

@aldnav Thank you for your suggestion. Your suggestion is definitely better!
I just make an adjustment in this refactor.
The fixed is in this comment f13ec7f

stats - tweets_count - following_count - followers_count

yimingStar · 2020-09-29T07:00:49Z

@yeachan153 Genuinely agree with your suggestion for the purpose of letting the user notice the missing web elements.
So I added the exception function into this Profile class, which will print out the missing attributes.

The fixed is in this commit c7bbf55

aldnav

The fix works. Left a minor comment. Overall LGTM. Thanks @yimingStar 👍

You shouldn't ignore a fatal error.

that was in the original package, so it's not related to this PR. Still, it should be ignored

HJoentgen · 2021-03-16T13:29:31Z

Is this solution still working?
When I use the new profile.py, I still get the same "local variable 'html' referenced before assignment" error, because of a 400 response.

So this:

from twitter_scraper import Profile
profile = Profile(f"BarackObama")
print(profile.to_dict())

leads to:

Unable to get is_private in html, exception - local variable 'html' referenced before assignment
