title: How is the syntax to apply inputs in jupyter-notebook for windows (python3)?
body: <p>I have this code that runs on PyCharm without problems:</p>
  
  <pre><code>dia = input()
  with open(f"FSC_{dia}.log", mode="r") as file, open(f"FSC_{dia}_saltopag.txt", mode="w") as wFile:
       for (...)
  </code></pre>
  
  <p>I'm trying to adapt it to jupyter-notebook - py3, but I got this syntax error:</p>
  
  <p><a href="https://i.stack.imgur.com/zenF7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zenF7.png" alt="unicodeescape error"></a></p>
  
  <p>I found in stackoverflow that I should type r before the path instead f to indicate it is a raw string, but when I set it as raw string it doesn't recognize me the input function:</p>
  
  <pre><code>FileNotFoundError                         Traceback (most recent call last)
  &lt;ipython-input-21-f4b2926639f7&gt; in &lt;module&gt;
  ----&gt; 1 with open(r"C:\Users\14122\PycharmProjects\LOGS_FSC\FSC_**{dia}**.log", mode='r') as file:
        2     counter = 0
        3     for f in file:
        4         counter = counter + 1
        5     print(counter)
  
  FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\14122\\PycharmProjects\\LOGS_FSC\\**FSC_{dia}.log**'
  </code></pre>
  
  <p>I think it is related to the way I set this raw string, anyone knows about it?</p>
  
  <p>Thanks in advance!</p>
