Not understanding the While(True) loop - Python 2.7 - python-2.7

Question

Having a hard time figuring out how the while(True) function is supposed to be fitted in the code. Also no idea if that is the right thing to use as I am trying to loop the game until the computer or the user hits the desired amount of points ( which the user inputs as rounds in the beginning)
import random
def main():
print
print "----------------------------------"
print "Welcome to Rock, Paper, Sciccors! "
print "----------------------------------"
rounds = input("How many points to win?: ")
user_choice = input("Choose Rock = 1 , Paper = 2 or Sciccors = 3: ")
user_score = 0
computer_score = 0
if user_choice == 1:
print "You chose Rock"
elif user_choice == 2:
print "You chose Paper"
elif user_choice == 3:
print "You chose Sciccors"
else:
print " Wrong! Choose 1, 2 or 3!"
computer_choice = random.randrange(1, 4)
if computer_choice == 1:
print "Computer chose Rock"
elif computer_choice == 2:
print "Computer chose Paper"
elif computer_choice == 3:
print "Computer chose Sciccors"
def checkResults(computer_choice, user_choice):
checkResults = computer_choice - user_choice
if computer_choice - user_choice == 0:
print("Draw!")
user_score += 1
computer_score += 1
elif computer_choice - user_choice == 1 or computer_choice - user_choice == -2:
print("Computer wins")
computer_score += 1
elif computer_choice - user_choice == -1 or computer_choice - user_choice == 2:
print("You win!")
user_score += 1
print (" Computer {} , You {}" .format(computer_score, user_score))
while(True):
if computer_score == rounds or user_score == rounds:
main()
else:
break

Answer 1

You can make this a bit shorter:
while computer_score == rounds or user_score == rounds:
' Your code returning computer_score and user_score
Basically a while True is an infinite loop that can only be ended using a break statement or via keyboard interrupt.

Answer 2

while True: is an infinite loop that can only be stopped via the command break. In your example, you have created a loop that will infinitely run the main() method (which you defined earlier, by saying def main():). The only time the loop will end is if you kill the process (i.e. using task manager on Windows), or if computer_score and user_score both become unequal to rounds (which is what your else statement is implying on the second to last line). When this happens, the program calls break which forcibly ends the loop immediately and moves on... to the end of the file (which then ends the program).
It should be noted that using a while True ... break loop is sometimes frowned upon by programmers, because it is not seen as "elegant". It is totally fine code to do, but another way to re-write the last few lines is the following:
while computer_score==rounds or user_score==rounds:
main()
This achieves the same result by running the while loop until computer_score and user_score both do not equal rounds. At that point, the while loop ends itself cleanly and ends the program by getting to the end of the file.
