title: Find on beautiful soup in loop returns TypeError
body: <p>I'm trying to scrape a table on an ajax page with Beautiful Soup and print it out in table form with the TextTable library.</p>
  
  <pre><code>import BeautifulSoup

  <p>Although the URL for the HTML in question I'm trying to scrape is shown in the code, here is an example of it:</p>
  
  <pre><code>&lt;table cellspacing="0" cellpadding="0"&gt;

  <p>Whenever I try to run this script function, it aborts with <code>TypeError: find() takes no keyword arguments</code> on the line <code>header_append = th.find(text=True)</code>. I'm sort of stumped, as it seems that I'm doing what is shown in code examples and it seems it should work, yet it doesn't.</p>
  
  <p>In short, how do I fix the code so that there is no TypeError and what am I doing wrong?</p>
  
  <p>Edit:
  Articles and documentation that I referred to when writing the script:</p>
