title: Why doesn't my script display the newly created file?
body: <p>I am writing a Python script that opens a file and for each test case, it should write the total number of items gathered in that case and display the total amount $ that it costs. </p>
  
  <p>When running my code:</p>
  
  <pre><code>f = open("shopping.txt", "r")
  outFile = open("results.txt", "w")
  t = int(f.readline().strip())
  for z in range(t):
      # Assuming prices are unique
      myList = {}
      items = int(f.readline().strip())
      ind = 1
      # Read each line for each item
      for i in range(items):
          p, w = map(int, f.readline().strip().split())
          myList[p] = [w, ind]
          ind+=1
      weights = []
      F = int(f.readline().strip())
      for i in range(F):
          weights.append(int(f.readline().strip()))
          RES = []
          values = []
      for weight in weights:
          sortedPrice = sorted(myList.keys())[::-1]
          m = 0
          p = 0
          tmp = []
  
          # Grabbing all possible results using greedy method
          # Max price stored into values array and item # in RES array.
      for i in range(len(myList)):
          R = []
          s = 0
          p = 0
          if myList[sortedPrice[i]][0]&lt;=weight:
              s=myList[sortedPrice[i]][0]
              p=sortedPrice[i]
              R+=myList[sortedPrice[i]][1],
      for j in range(i+1, len(myList)):
          if myList[sortedPrice[j]][0]+s&lt;=weight:
              s+=myList[sortedPrice[j]][0]
              p+=sortedPrice[j]
              R+=myList[sortedPrice[j]][1],
          if m&lt;p:
              m = p
              tmp = R
              tmp.sort()
              RES.append(tmp)
              values.append(m)
      outFile.write("Test Case %d\n" %(z+1))
      outFile.write("Total Price: %d\n" %(sum(values)))
      outFile.write("Member Items:\n")
      for i in range(len(RES)):
          outFile.write("%d: %s" %(i+1, " ".join(map(str, RES[i]))))
          f.close()
          outFile.close()
  </code></pre>
  
  <p>I get the result:</p>
  
  <pre class="lang-none prettyprint-override"><code>Test Case 1
  Total Price: 0
  Member Items:
  Test Case 2
  Total Price: 0
  Member Items:
  </code></pre>
  
  <p>When I expected something like this:</p>
  
  <pre class="lang-none prettyprint-override"><code>Test Case1
  Total Price 72
  Member Items
  1: 1
  Test Case2
  Total Price 568
  Member Items
  1: 3 4
  2: 3 6
  3: 3 6 
  4: 3 4 6
  </code></pre>
  
  <p>I am relatively new to programming in general so if there is any insight anyone could give for my code, I would appreciate it. Adding to this, my guess is that the <code>sum()</code> and/or the <code>map</code> commands may be breaking and not working as intended, as I'm writing to the file to get the total value and items of the case.</p>
