title: Max function in python returning wrong results
body: <p>I am trying to find the Max and Min in a set of numbers from a CSV file. My code keeps returning the wrong number for Max function for some rows. Here is my code:</p>
  
  <pre><code>with open('Cortex_vs_Liver_trial.csv', newline='') as infile:
      reader = csv.reader(infile)
  
      for row in reader:
          print(row)
          print('The maximun is:', max(row))
          print('The minimum is:', min(row))
  </code></pre>
  
  <p>An example of my output:</p>
  
  <pre><code>['86.21', '100.00', '96.30']
  The maximun is: 96.30
  The minimum is: 100.00
  </code></pre>
  
  <p>I am not sure what I have done wrong. Some advice would be appreciated.</p>
