使用python将helloworld字符串倒序排序

def bubbleSort(string):
    lst = [ord(i) for i in string]
    for i in range(len(lst) - 1):
        for j in range(len(lst) - 1 - i):
            if lst[j+1] > lst[j]:
                temp = lst[j+1]
                lst[j+1] = lst[j]
                lst[j] = temp
    return lst


if __name__ == '__main__':
    string = 'helloworld'
    sortData = bubbleSort(string)
    newlst = []
    for k in sortData:
        newlst.append(chr(k))
    print(''.join(newlst))
