title: what do i write to fill the space of the line 4 code such that it prints true if n is a prime since it returns true no matter what
body: <p>i mathematically find it difficult to compose a code to fill the line 4 in the below code</p>
  
  <pre><code>is_prime = True
  for i in range(2,n):
      if n%i == 0:
          print("impossible")
  print(is_prime)
  </code></pre>
  
  <p>i have been typing print(string) i.e</p>
  
  <p>print("this is not possible")
  in the blank and it output </p>
  
  <pre><code>true
  </code></pre>
  
  <p>what is the correct code to write. i want to believe it is a mathematics expression thing.i don't know the code to write after if.</p>
