title: Saying to no to a command in jupyter
body: <p>I am executing a terminal command inside of a for loop in Jupyter Notebook. However, the command doesn't run because you need to enter y or n after running it. I have tried adding a -y to the end, but that doesn't help. I also tried adding a ! y after but that didn't help as well. I am not getting an error though.</p>
  <p><code>! python3 nii2png.py -i /Users/coder/Desktop/Training_Data/HGG/HGG1.nii -o /Users/coder/Desktop/Training_Data_Output/HGG</code></p>
  <p>Then it returns &quot;Would you like to rotate the orientation? (y/n)&quot;, but no prompt to enter it.</p>
  <p>I would really appreciate any help with this!</p>
