Why Can't I Update The Pygame Window In Real Time Using The Python Command Line

Question

I am trying to make a program in Python using the Pygame Library. I want to give the pygame window information from the python command line while the window is active. Everything seems to be working but it is not drawing the Shapes to the screen and Crashes the pygame window when i try to draw to it. I can't seem to find the problem or cause for this and i've run into this problem before. The code is provided below and is messy as i'm learning. Is it possible to circumvent this or do i have to completely recreate the code.

Multithreading is an option but i am not sure how to implement it to fit my code.

    import pygame
    import sys

    Black = 0,0,0
    White = 255,255,255
    Blue = 0,0,255
    Red = 255,0,0
    Green = 0,255,0
    Commands = ["Pygame Start", "Pygame End", "Help", "Exit", "Clear Screen", "DrawMode", "Display Update"]
    Types = ["Player", "Enemy"]
    PlayerRect = [0,0,0,0]
    DrawPlayer = False
    pygame.init()
    def Console():
        print "Commands: ", "\n", Commands[0],"\n", Commands[1],"\n", Commands[2], "\n", Commands[3], "\n", Commands[4], "\n", Commands[5], "\n", Commands[6]
        Input = raw_input("// ")

        if Input == Commands[0]:
            Window(True)

        if Input == Commands[1]:
            Window(False)

        if Input == Commands[2]:
            Help()

        if Input == Commands[3]:
            sys.exit()

        if Input == Commands[4]:
            pygame.draw.rect(screen,Blue,NewPlayerRect)

        if Input == Commands[5]:
            DrawMode()

        if Input == Commands[6]:
            DisplayUpdate()

    def Window(Active):
        if(Active == True):
            global screen
            screen = pygame.display.set_mode((640,480))



        elif(Active == False):
            pygame.display.quit()

    def Help():
        print "What Command Do You Need Explained?\n"
        KindOfHelp = raw_input("// ")

        if KindOfHelp == Commands[0]:
            print("\nTurns on the Pygame Module, which opens a pygame window")

        if KindOfHelp == Commands[1]:
            print("\nTurns off the Pygame Module, which closes a pygame window")

        if KindOfHelp == Commands[2]:
            print("\nOpens the Help Screen")

    def CLS():
        print "\n" * 100

    def DisplayUpdate():
        pygame.display.update()

    def DrawMode():
        print "Things you are able to  Create are a: ","\n", Types[0], "\n", Types[1]
        Type = raw_input("What Do you Want to Create? ")

        if Type == Types[0]:
            PlayerPosX = int(raw_input("Where Should The Player Spawn On The X Axis? "))
            PlayerPosY = int(raw_input("Where Should The Player Spawn On The Y Axis? "))
            PlayerSizeX = int(raw_input("What Should The Player X Size Be?"))
            PlayerSizeY = int(raw_input("What Should The Player Y Size Be?"))
            PlayerRect[0] = PlayerPosX
            PlayerRect[1] = PlayerPosY
            PlayerRect[2] = PlayerSizeX
            PlayerRect[3] = PlayerSizeY
            DrawPlayer = True



    while True:
        X = PlayerRect[0]
        Y = PlayerRect[1]
        XSize = PlayerRect[2]
        YSize = PlayerRect[3]
        NewPlayerRect = (X,Y,XSize,YSize)

        print(X,Y,XSize,YSize)
        Console()
