title: Check pytesseract version using python
body: <p>Is there a way to check pytesseract version in python?<br>
  According to <a href="https://pypi.org/project/pytesseract/" rel="nofollow noreferrer">PyPi documentation</a> of pytesseract, there is a built-in function <code>get_tesseract_version</code> to get pytesseract version. But when I run it in python, I get the following:  </p>
  
  <pre><code>&gt;&gt;&gt; import pytesseract
  &gt;&gt;&gt; pytesseract.get_tesseract_version
  &lt;function get_tesseract_version at 0x7f4b9edd4598&gt;
  &gt;&gt;&gt; print(pytesseract.get_tesseract_version)
  &lt;function get_tesseract_version at 0x7f4b9edd4598&gt;
  </code></pre>
  
  <p>I know that I can get pytesseract version using <code>pip freeze</code>, but I want to get it using python. Is that possible?</p>
