How to break between loop by creating a condition in python

lst = []
while True:
    try:
        arr = int(input("Enter number of elements: "))
        if arr == "Quit":
            break
    except ValueError:
        print("Invalid Input")
        continue
    else:
        break
while True:
    try:
        for i in range(0, arr):
            ele = int(input("Enter the elements:"))
            lst.append(ele)
            print(lst)
    except ValueError:
        print("Invalid Input")
        continue
    else:
        break

How can I create a condition to exit the program at any point in the loop by specifically entering the conditioned term? Like when it asks me to enter an element, but i want to break the program right at that point by entering "Quit". How to do that in this code? (Learner)
