TypeError: Type str doesn't support the buffer API # find method?

python, python-3.x

Solution

You can't use `bytes.find()` to find a `str` object inside a `bytes` object(since they're different types, a `str` can't be inside `bytes`). You can, however, look for a bytes object inside it. This should work:

start_link = input.find(b' <p class="js-tweet-text tweet-text" ')

Btw, you should be using an html parser if you're parsing html.

Problem

Here is my input: ``` <!DOCTYPE html> .......... <div class="content"> <div class="stream-item-header"> <a class="account-group js-account-group js-action-profile js-user-profile-link js-nav" href="https://twitter.com/jimcramer" data-user-id="14216123"> <img class="avatar js-action-profile-avatar" src="Twitter%20_%20Search%20-%20%23tsla_files/988b4c2369623b634782f4c0469ec38f_normal.jpg" alt=""> <strong class="fullname js-action-profile-name show-popup-with-id">Jim Cramer</strong> <span>‏</span><span class="username js-action-profile-name"><s>@</s><b>jimcramer</b></span> </a> <small class="time"> <a href="https://twitter.com/jimcramer/status/405348028417994752" class="tweet-timestamp js-permalink js-nav js-tooltip" title="3:51 PM - 26 Nov 13"><span class="_timestamp js-short-timestamp " data-time="1385477475" data-long-form="true">26 Nov</span></a> </small> </div> <p class="js-tweet-text tweet-text">Love this spirited &amp; rigorous <a href="https://twitter.com/search?q=%24TSLA&amp;src=ctag" data-query-source="cashtag_click" class="twitter-cashtag pretty-link js-nav" dir="ltr"><s>$</s><b>TSLA</b></a> defense !

Here is my code: ``` start_link = input.find(' <p class="js-tweet-text tweet-text" ') ``` if i run it, i'll get the following error: ``` start_link = input.find('<p class="js-tweet-text tweet-text" ') TypeError: Type str doesn't support the buffer API ``` How can I fix this? NOTE: type of my input variable is: `class 'bytes'`
