title: Trying to get all prime numbers in an array in Python
body: <p>I am trying to print out all prime numbers that are in an array called 'checkMe'. But I just can't get it to work. I've succesfully made a program that checks it for one number but it doesn't work for an array. If anyone knows what is wrong on please tell me. BTW: I am a big noob in python so it probably isn't the most beautiful code. </p>
  
  <pre><code>checkMe = range(1, 100)
  
  dividers = []
  primes = []
  
  for y in checkMe:
      x = y
      for x in range(2, x):
          if (y/x).is_integer():
              dividers.append(x)
      if len(dividers) &lt; 2:
          primes.append(y)
  
  print("\n"+str(checkMe)+" has "+str(len(primes))+" primes")
  print(primes)
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>range(1, 100) has 5 primes
  [1, 2, 3, 4, 5]
  </code></pre>
  
  <p>Expected Output:</p>
  
  <pre><code>range(1, 100) has 25 primes
  [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83,
  89, 97]
  </code></pre>
