title: TypeError: create_purple() takes 0 positional arguments but 2 were given
body: <p>I am brand new to Python programming and trying to make this program work. </p>
  
  <p>I have made this program work by using "if" and "else" statements only, however, I wanted to make this same program with the method below. When I run the program I keep getting an error "TypeError: create_purple() takes 0 positional arguments but 2 were given" and I cannot figure out why.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>#*******************************************************************************************
  #
  # This program will take any two primary colors and create a secondary color.
  #
  # Primary colors are:
  # Blue, Red, Yellow
  # 
  # Secondary colors are:
  # Green, Orange, Purple
  #
  
  #Clear the screen
  import os
  os.system('cls') 
  
  RED = "red"
  BLUE = "blue"
  YELLOW = "yellow"
  
  def main():
      print ('\n')
      # Tell the user the objective of the program.
      print ('*****************************************************************************')
      print ('*****************************************************************************')
      print ('\n')
      print ('The objective of this program is to create a secondary color from two primary')
      print ('colors. When asked, choose two primary colors (Red, Blue, or Yellow) to create')
      print ('a secondary color ')
  
      # Choose your colors
      color1 = input('Enter your first primary color: ')
      color2 = input('Enter your second primary color: ')
  
      # Determine the secondary color
      if color1 == RED and color2 == BLUE:
      create_purple(color1,color2)
  
  
  def create_purple():
  
      # Determine the color is purple
      if color1 == RED and color2 == BLUE:
          print ('\n')
          print ('You have made the color.... Purple ')
      else:
          if color1 == BLUE and color2 == RED:
              print ('\n')
              print ('You have made the color.... Purple ')
  
  # Call the main function
  main()
  </code></pre>
