title: Jupyter does not see changes in the imported module
body: <p>I have a file called &quot;Notebook.ipynb&quot;. I want to import my own module into it patterns.py. Let's say in patterns.py I have a variable <code>a=1</code>. If I print it in Jupyter after importing it, I expect to get 1. But if I change the value of the variable to patterns.py Jupyter will continue to think that the variable <code>a</code> is equal to one. At the same time, of course, I restart the cell in which the variable is imported from patterns.py</p>
  <p>What do I need to do to make Jupyter understand that the value of the variable has changed?</p>
