title: Python min, max, mean, median code function define error
body: <p><strong>Here's my code:</strong> Any help would be appreciated. Stuck on returning an error 'int' is not iterable and not sure where to go from there. Receiving error when running first part of my function at #minimum.</p>
  
  <pre><code> #Minimum
  min_val = min(input_list)
  int(min_val)
  return min_val
  
  #Maximum
  max_val = max(input_list)
  int(max_val)
  return max_val
  
  #Mean
  total = sum(input_list)
  length = len(input_list)
  for nums in [input_list]:
      mean_val = total / length
      float(mean_val)
      return mean_val
  
  #Median
  sorted(input_list)
  med_val = sorted(lst)
  lstLen = len(lst)
  index = (lstLen - 1) // 2
  
  if (lstLen % 2):
      return med_val[index]
  else:
      return (med_val[index] + med_val[index + 1])/2.0
  
  return min_val, max_val, mean_val, med_val
  </code></pre>
