When I make requests using Beautiful Soup, I get blocked as a "bot".

import requests
from bs4 import BeautifulSoup

reddit1Link = requests.get("

    I used to use Mechanize for stuff like this, it has been a couple of years, but it should still work.

    Try something like this:

    from mechanize import Browser
    from bs4 import BeautifulSoup
    
    b = Browser()
    b.set_handle_robots(False)
    b.addheaders = [('Referer', 'https://www.reddit.com'), ('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')]
    
    b.open('https://www.reddit.com/r/tensorflow/comments/650p49/question_im_a_techy_35_year_old_and_i_think_ai_is/')
    soup = BeautifulSoup(b.response().read(), "html.parser")
    

    EDIT:

    I just realized that, sadly, mechanize is only availble for python 2.5-2.7, there are however, other options available. See Installing mechanize for python 3.4

    There can be various reasons for being blocked as a bot.

    As you are using the requests library "as is", the most probable reason for the block is a missing User Agent header.

    A first line of defense against bots and scraping is to check the User Agent header for being from one of the major browsers and block all non-browser user agents.

    Short version: try this:

    import requests
    from bs4 import BeautifulSoup
    
    headers = requests.utils.default_headers()
    headers.update({
        'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0',
    })
    
    reddit1Link = requests.get("https://www.reddit.com/r/tensorflow/comments/650p49/question_im_a_techy_35_year_old_and_i_think_ai_is/", headers=headers)
    reddit1Content =BeautifulSoup(reddit1Link.content,"lxml")
    print(reddit1Content)
