title: How can I get this Tkinter program to detect files properly?
body: <p>I am brand new to Python, and decided to jump headfirst into a small project.
  I'm using Tkinter to make a GUI, and I will have a score that updates when certain things are done on a VM.</p>
  <p>Problem- I am trying to have a variable be updated (Higher Score) when a file is not present on the computer. I have the file present, but it always tells me that it's not there. When I    try and print the variable, the score isn't where it should be.</p>
  <p>I've been looking for a way to fix this, but I haven't found anything.</p>
  <p>Here is my code-</p>
  <pre><code>import tkinter as tk
  window = tk.Tk()
  
   # Heading
  Word = tk.Label(text=&quot;Score: &quot;)
  Word.pack()
  
   # Variable for score
  x = 0
  Score = tk.Label(text=x)
  Score.pack()
   # File exists
  # Issue: Files always maked as false
  import os
  PATH = 'file.txt'
  if os.path.isfile(PATH) and os.access(PATH, os.R_OK):
   p(x + 0)
  else:
   (x + 10)
  print(x)
  window.mainloop()import os
  
  </code></pre>
