Guessing random number game python

My program is supposed to ask the user to guess a number between 0 and 100 however I can't seem to get the output right. At the moment if the the User number is greater than the random number, it prints out an infinite amount of "Your number is too high." Also if the first UserGuess is low, then all the following numbers will have the same prompt: ("Your number is too low") despite them being actually bigger than the random number. I have no idea what I am doing wrong. Any help would be greatly appreciated. Thank you!

from random import randint

def main():

guessesTaken = 0

randomNumber = randint(0,100)
#print(randomNumber)
giveUp = -1
UserGuess = int(input("Take a guess" + "(The random number is: " + str(randomNumber) + "): "))

while UserGuess != randomNumber:

    guessesTaken += 1

    if UserGuess < randomNumber:
        print("Your guess is too low.")

    elif UserGuess > randomNumber:
        print("Your guess is too high.")

    elif UserGuess == randomNumber or UserGuess == giveUp:
        break

if UserGuess  == randomNumber:
    guessesTaken = str(guessesTaken)
    print("Yes, that is right!")
    print("It took you " + guessesTaken +  " guesses")
if UserGuess == giveUp:
    guessesTaken = str(guessesTaken)
    randomNumber = str(randomNumber)
    print("Better luck next time.")
    print("You tried"+ guessesTaken +  " guesses")


return
print (main())

if __name__ == "__main__":
     main()
