Python 为什么我的while命令不起作用？

我不明白为什么我的代码在打印“从8开始”时停止工作

为什么不把数字8和数字5，8，12，18，22进行比较

#Sum of two lowest integers
numbers = [5,8,12,18,22]
keep_ans = []
limit = len(numbers)
for i in numbers:
    print("Start with "+str(i))
    run = 0
    check_in = 0
    Done = False #It's stop here, when i = 8
    while Done == False:
        if i <= numbers[check_in]:
            print("Compare "+str(i)+" with "+str(numbers[check_in])+" round:"+str(run))
            run += 1
            check_in += 1
        if run == limit-1:
            keep_ans.append(i)
            Done = True
ans = sum(keep_ans)
print(ans)

您陷入了

的while

循环中，因为在第二次迭代中，您没有输入第一个

if

-条件，因此从未向

运行
和
签入中添加1

要解决此问题，您需要更改缩进：

while Done == False:
    if i <= numbers[check_in]:
        print("Compare "+str(i)+" with "+str(numbers[check_in])+" round:"+str(run))
    run += 1
    check_in += 1

完成时==False:
如果我我得到了我的答案！，多谢各位

numbers = [5,8,12,18,22]
keep_ans = []
print("Number => "+str(numbers))
for i in numbers:
    print("Start with  >  "+str(i)+"  <")
    point = 0
    round = 0
    limit = len(numbers)
    for i2 in numbers:
        print("     Compare with :"+str(numbers[point]))
        if i < i2:
            round += 1
            #print("     get")
        point += 1
        if round == limit-2:
            #print("Added!!!!!")
            keep_ans.append(i)
            break
    #print(keep_ans)
print("Two lowest numbers = "+str(keep_ans))
print("Sum of two lowest numbers = "+str(sum(keep_ans)))

Two lowest numbers = [5, 8]
Sum of two lowest numbers = 13

number=[5,8,12,18,22]
保持一致性=[]
打印（“数字=>”+str（数字））
以数字表示的i：
打印（“开始>”+STR（i）+“考虑在您的代码中发生了什么”，而<>代码>循环，如果它内部的条件都没有被评估为真。
