Question

我想从用户那里获得一系列字符串，并将其放入列表中，然后打印出来

我也想在完成后关闭列表并打印

list = []
for i in list:

    list[a]=input('the name of stings:')
    list.append(list[a])
    a +=
    print(list)

Answer 1

尝试一下：

list_ = []
not_done = True
while not_done:
    inp = input('name of string : ')
    if inp.lower() != 'done': # Put any string in stead of 'done' by which you intend to not take any more input
        list_.append(inp)
    else:
        break
print(list_)

输出：

name of string : sd
name of string : se
name of string : gf
name of string : yh
name of string : done
['sd', 'se', 'gf', 'yh']

Answer 2

您可以执行以下操作：

n = int(input())

my_list = list()
for i in range(n):
    my_str = input('Enter string ')
    my_list.append(my_str)
    print('You entered', my_str)
    print(my_list)

以下是示例（第一行采用数字，表示要输入多少次）：

4
Enter string abc
You entered abc
['abc']
Enter string xyz
You entered xyz
['abc', 'xyz']
Enter string lmn
You entered lmn
['abc', 'xyz', 'lmn']
Enter string opq
You entered opq
['abc', 'xyz', 'lmn', 'opq']

Answer 3

N = 10  # desired number of inputs

lst = []  # don't use `list` as it's resereved
for i in range(N):
    lst.append(input('the name of strings: ')

print(lst)

Answer 4

示例如下：

startService()

输出：

    public BackgroundTaskWorker(@NonNull Context context, @NonNull WorkerParameters workerParams) {
        super(context, workerParams);
    }
    @Override
