how to put a quit loop in a bubble sort with user input in python code example

Example 1: bubble sort in python

def bubble_sort(arr):
    x=-1
    n=len(arr)#length of array 6
    for i in range (0,n):
        for j in range(1,n-i):
            if arr[j-1]>arr[j]:
                arr[j-1],arr[j]=arr[j],arr[j-1]
        if (n-i)<=1:
            break
    return arr
            
if "__main__"==__name__:
    arr=[7,1,2,6,9,3,8,4]
    result=bubble_sort(arr)
    print(result)

Example 2: bubble sort python

def bubble_sort(arr):
    def swap(i, j):
        arr[i], arr[j] = arr[j], arr[i]

    n = len(arr)
    swapped = True
    
    x = -1
    while swapped:
        swapped = False
        x = x + 1
        for i in range(1, n-x):
            if arr[i - 1] > arr[i]:
                swap(i - 1, i)
                swapped = True
                    
    return arr
