Answer 1

Note: Implemented as asked. Please comment for further help. Please uprate.

Also update time to 45 in line 23.

Code:

from graphics import *
import random
import time

def main():
win = GraphWin('Message', 400, 400,autoflush=False) # give title and dimensions
listOfMessages=['First Message','Second Message','Third Message'] #list of messages
while True: #infinite loop
timeBegin = time.time() #variable to store start time
choosenMessage = random.choice(listOfMessages) #randomly select message from list
message = Text(Point(win.getWidth()/2, win.getHeight()/2), choosenMessage) #mid point of screen
message.draw(win) #draw message
win.update() #update window
timeEnd = time.time() #take end time
timeElapsed = timeEnd - timeBegin #calculate timeElapsed
time.sleep(max(0, 5-timeElapsed)) #sleep for 5 seconds. Update it to 45 for 45 seconds
message.undraw() # remove message from screen
  
win.getMouse() #on mouse click close window
win.close()

main()
