You don't mention what environment you're running in, which makes a big difference because there isn't a pure Python web browser that's capable of rendering HTML.

But if you're using a Mac, I've used <a href="http://www.paulhammond.org/webkit2png/" rel="nofollow noreferrer">webkit2png</a> with great success. If not, as others have pointed out there are plenty of options.

On the Mac, there's <a href="http://www.paulhammond.org/webkit2png/" rel="noreferrer">webkit2png</a> and on Linux+KDE, you can use <a href="http://khtml2png.sourceforge.net/" rel="noreferrer">khtml2png</a>. I've tried the former and it works quite well, and heard of the latter being put to use. 

I recently came across <a href="http://www.blogs.uni-osnabrueck.de/rotapken/2008/12/03/create-screenshots-of-a-web-page-using-python-and-qtwebkit/" rel="noreferrer">QtWebKit</a> which claims to be cross platform (Qt rolled WebKit into their library, I guess). But I've never tried it, so I can't tell you much more.

The QtWebKit links shows how to access from Python. You should be able to at least use subprocess to do the same with the others.

Using a web service s-shot.ru (so it's not so fast), but quite easy to set up what need through the link configuration.
And you can easily capture full page screenshots

<pre><code>import requests

BASE = 'https://mini.s-shot.ru/1024x0/JPEG/1024/Z100/?' # you can modify size, format, zoom
url = 'https://stackoverflow.com/'#or whatever link you need
url = urllib.parse.quote_plus(url) #service needs link to be joined in encoded format
print(url)

path = 'target1.jpg'
response = requests.get(BASE + url, stream=True)

if response.status_code == 200:

I created a library called pywebcapture that wraps selenium that will do just that:
<pre><code>pip install pywebcapture
</code></pre>
Once you install with pip, you can do the following to easily get full size screenshots:
<pre><code># import modules
from pywebcapture import loader, driver

# load csv with urls
csv_file = loader.CSVLoader(&quot;csv_file_with_urls.csv&quot;, has_header_bool, url_column, optional_filename_column)
uri_dict = csv_file.get_uri_dict()

# create instance of the driver and run
d = driver.Driver(&quot;path/to/webdriver/&quot;, output_filepath, delay, uri_dict)
d.run()
</code></pre>
Enjoy!
