title: New to Python.. Gradepoint AVG?
body: <p>Rather than asking the user to enter a number, modify gpa.py to enter 5 grades, but make it letter grades
  (A, A-, B+, etc). Please input these grades, convert them to 4 point scale equivalents, (a=4.0, a- = 3.7, B+ =3.3, B= 3.0, B- = 
  2.7, C+ =2.3, C = 2.0, C- =1.7 etc.). Print out the numeric equivalent of the average of these 5 grades.</p>
  
  <p>originally for the first program i did i had</p>
  
  <pre><code>print("This program calculates grade point average.")
  g1 = float(input("Enter course 1 grade -&gt; "))
  g2 = float(input("Enter course 2 grade -&gt; "))
  g3 = float(input("Enter course 3 grade -&gt; "))
  g4 = float(input("Enter course 4 grade -&gt; "))
  g5 = float(input("Enter course 5 grade -&gt; "))
  sum = g1 + g2 + g3 + g4 + g5
  count = 5
  print ("Your GPA for last semester was -&gt; ", sum / count)
  </code></pre>
  
  <p>but after reading this it tells me it wants me to assign grades, so i made it this</p>
  
  <pre><code>print("This program calculates grade point average.")
  g1 = a
  g2 = b
  g3 = c
  g4 = c+
  g5 = b-
  sum = g1 + g2 + g3 + g4 + g5
  count = 5
  print ("Your GPA for last semester was -&gt; ", sum / count)
  </code></pre>
  
  <p>how can i make the grades from strings to ints and then give the grade point average?</p>
