def bubbleSort(numbers):
    for j in xrange(len(numbers)-1,-1,-1):
        for i in xrange(j):
            if numbers[i] > numbers[i+1]:
                numbers[i],numbers[i+1]=numbers[i+1],numbers[i]#在python中，元组其实是由逗号“,”来界定的，而不是括号
    return numbers

def main():
    numbers=[23,12,9,15,6]
    numbers=bubbleSort(numbers)
    for num in numbers:
        print num,#不输出换行
    print "n",
    print numbers
if __name__ == '__main__':
    main()

6 9 12 15 23
[6, 9, 12, 15, 23]
