title: Implement a function which takes a list of numbers as an argument and returns true if that list only contains prime numbers and false if it does not
body: <p>Any ideas? So far this just takes a single number and states if it is or isn't a prime number.</p>
  
  <pre><code>*a = input('enter a number: ')
      s = 0
      if a == 1:  
          print a, 'is a prime number'
  
      else : 
  
          for i in range (2, a ):
  
              if a%i == 0:
                  print a,' is not a prime number'
                  s = 'true'
                  break
  
          if s == 0 : print a,' is a prime number'*
  </code></pre>
