My Python thread starts but doesn't do anything

Question

I'm working on custom basic functions to simplify coding for me, like wait(seconds) or msg(...), and now I'm working on the window setup and updating, it works, but when I put it in a thread, it just won't do anything. I don't get any errors, so I'm confused and frustrated. I dont need you to debug it or anything, I just need help to know where the problem is and why it's a problem.

Here's my script so far (the script is at the bottom):

#   Imports
if True:
    import pygame, math, random, time, sys, threading
    from pygame.locals import *
    pygame.init()


#   Setup
if True:
    win_n = "New Project"
    win_w = 800
    win_h = 600
    win_c = (0, 0, 0)

#   Code
if True:
    def wait(seconds):
        time.sleep(seconds)
    def wait_until(bool):
        while not bool:
            wait(0.001)

#   Execute
if True:
    def e_ws():
        mainClock = pygame.time.Clock()
        pygame.display.set_caption(win_n)
        monitor_size = [pygame.display.Info().current_w, pygame.display.Info().current_h]
        screen = pygame.display.set_mode((win_w, win_h), pygame.RESIZABLE)
        fullscreen = False
        while True:
            screen.fill(win_c)
            for event in pygame.event.get():
                if event.type == QUIT:
                    pygame.quit()
                    sys.exit()
                if event.type == VIDEORESIZE:
                    if not fullscreen:
                        screen = pygame.display.set_mode((event.w, event.h), pygame.RESIZABLE)
                if event.type == KEYDOWN:
                        if fullscreen:
                            screen = pygame.display.set_mode(monitor_size, pygame.FULLSCREEN)
                        else:
                            screen = pygame.display.set_mode((screen.get_width(), screen.get_height()),
                                                             pygame.RESIZABLE)
            pygame.display.update()
            mainClock.tick(60)
    t_ws = threading.Thread(target=e_ws)
    t_ws.start()
    print("done")

Run a script with python yourscriptname.py from the command line.
