title: How to add a new folder to the directory you are in in jupyter notebook
body: <p>I am working with python and jupyter notebook, and I am writing code to save images to a folder. However, I am getting the error 'FileNotFoundError: [Errno 2] No such file or directory: 'plots/plot0.jpg'. I believe this is because I do not have a folder 'plots' in the current directory, and I was wondering how do add this. I have attached some code to see what is in the directory and how I am saving this image. Thank you!</p>
  <pre><code>img.save(&quot;plots/plot&quot; + str(j) + &quot;.png&quot;)
  </code></pre>
  <p>I ran this code:</p>
  <pre><code>import os
  os.listdir()
  </code></pre>
  <p>and 'plots' was not in there, does this mean I need to create a new folder, and if so, how do I do that? Thank you!</p>
