title: Detect lowest value from user input in Python 3.6
body: <p>I have to calculate the average grade for a set of values based on user input, while dropping the lowest grade before calculating the average. I have everything except for the code to drop the lowest value. I tried using the min function, but when printed inside the loop I get "TypeError: 'int' object is not iterable." Any idea how to fix this? Thanks!</p>
  
  <pre><code>numuser=eval(input("How many users are there?: "))
  numgrade=eval(input("How many grades will there be for each user?: "))
  usercount=0
  gradecount=0
  
  while usercount &lt;= numuser:
      name=input("Please enter the user's first and last name: ")
      gradetot=0
      while gradecount &lt; numgrade:
          gradeval=eval(input("Please enter the grade: "))
          gradetot=gradetot+gradeval
          gradecount=gradecount+1
  
  low = min(gradeval)
  tot = gradetot-low
  
  print("The average grade for", name, "is :", tot/gradecount)
  numuser=numuser-1
  usercount=usercount+1
  gradecount=0
  </code></pre>
