title: Python 3 : Rock, Paper, Scissor game - how to define counts for the wins and picks
body: <p>I'm new to Python. Need to create the game Rock, Paper, Scissors in Python 3 that prints out at the end of the game:</p>
  
  <pre><code>The number of rounds the computer has won.
  The number of rounds the user has won.
  The number of rounds that ended in a tie
  The number of times the user selected each weapon (Rock, Paper, Scissors).
  </code></pre>
  
  <p><strong>Note</strong>: Computer should select the weapon most likely to beat the user, based on the user’s previous choice of weapons, but its choice will not be displayed until later so the user doesn’t see it. For that computer keeps a count of how many times the user has selected each weapon (Rock, Paper or Scissors). </p>
  
  <p>Example, if the user has selected Rock and Paper 3 times each and Scissors only 1 time, or if the user has selected each of the weapons an equal number of times, then there is no single weapon that has been used most frequently by the user; in this case the computer may select any of the weapons.</p>
  
  <p>My code is next:</p>
  
  <pre><code># Import random function
  import random
  
  # After the round ask the user if he/she would like to play the game again
  def display_intro():
      print("Welcome to Rock, Paper and Scissors Game!")
      play_game = input("Would you like to play with me?\n"
                    "y/n").lower()
      if play_game == "y" or play_game == "yes" or play_game == "Y":
          print("Let\'s start playing!")
          get_comp_choice()
      elif play_game == "n" or play_game == "no" or play_game == "N":
          print("Thanks for playing")
          print("Computer won", compWinCt, "times.")"" \
          print("User won", userWinCt, "times.")
          print("Draw games count is: ",drawCt)
          print("User picked Rock", userRockCt, "times.")
          print("User picked Paper", userPaperCt, "times.")
          print("User picked Scissors", userScissors, "times.")
          quit()
      else:
          print("That's now a valid choice. Please try again!")
      display_intro()
  
  
  # define random choice pick

      comp_choice = random.randint(1, 3)

          comp_choice = "p"
      elif comp_choice == 3:
          comp_choice = "s"
      return comp_choice
  
  # define computer choice base on what user has chosen in previous rounds
  def get_comp_choice():
      if userRockCt == 0 and userPaperCt == 0 and userScissorsCt == 0:
          return get_random_choice()

  main()
  </code></pre>
  
  <p>I don't know if I am misplacing the order of define function or missing something. When I run the code I get this error.</p>
  
  <pre><code>Traceback (most recent call last):
    File "C:/Users/.../Test", line 123, in &lt;module&gt;
      main()
    File "C:/Users/.../Test", line 64, in main
      comp_choice = get_comp_choice()
    File "C:/Users/.../Test", line 43, in get_comp_choice
      if userRockCt == 0 and userPaperCt == 0 and userScissorsCt == 0:
  NameError: name 'userRockCt' is not defined
  
  Process finished with exit code 1
  </code></pre>
  
  <p>And just looking at the code I can tell that the same issue will be with userPaperCt, userScissorsCt at get_comp_choice</p>
  
  <p>and at def display_intro() with compWinCt, userWinCt and DrawCt</p>
  
  <p>I've seen some examples of using global but I'm trying to avoid using it.</p>
