Question

我正在努力在电报机器人上创建键盘。我想创建一些按钮。我有一个问题，我想创建一个向下滑动的键盘。有一个问题，json 你可以通过代码 n1 创建它，但在 python 我找不到解决方案。那么我如何转换'lista = ["New York","Los Angeles","Miami","Toronto","Berlin","Rome"]'in json（代码 n1）？

#code n1 (JSON)
{"keyboard": [[{"text": "New York"}, {"text": "Los Angeles"}],
                         [{"text": "Miami"}, {"text": "Toronto"}],
                         [{"text": "Berlin"}, {"text": "Rome"}]]}


#code2
import json
import time
from pprint import pprint
import telepot
from telepot.loop import MessageLoop
bot = telepot.Bot("token")
lista = ["New York","Los Angeles","Miami","Toronto","Berlin","Rome"]
kdict = []
for i in lista:
    kdict.append({"text": i})
    print(kdict)
keyboard = {"keyboard": [kdict]}



def handle(msg):
    content_type, chat_type, chat_id = telepot.glance(msg)
    print(content_type, chat_type, chat_id)

    if content_type == "text":
        bot.sendMessage(chat_id, msg["text"], reply_markup=keyboard)


MessageLoop(bot, handle).run_as_thread()
while 1:
    time.sleep(10)

Answer 1

要对列表中的项目进行配对，您可以从列表中创建一个迭代器，将迭代器与自身压缩，然后使用列表推导式对压缩对进行迭代：

seq = iter(lista)
[[{'text': i} for i in pair] for pair in zip(seq, seq)]

这个returns:

[[{'text': 'New York'}, {'text': 'Los Angeles'}],
 [{'text': 'Miami'}, {'text': 'Toronto'}],
 [{'text': 'Berlin'}, {'text': 'Rome'}]]

然后您可以使用 json.dumps 将其转换为 JSON。

使用blhsing答案

#code n1 (JSON)
{"keyboard": [[{"text": "New York"}, {"text": "Los Angeles"}],
                         [{"text": "Miami"}, {"text": "Toronto"}],
                         [{"text": "Berlin"}, {"text": "Rome"}]]}


#code2
import json
import time
from pprint import pprint
import telepot
from telepot.loop import MessageLoop
bot = telepot.Bot("token")
lista = ["New York","Los Angeles","Miami","Toronto","Berlin","Rome"]

seq = iter(lista)

keyboard = {"keyboard": [[{'text': i} for i in pair] for pair in zip(seq, seq)]}



def handle(msg):
    content_type, chat_type, chat_id = telepot.glance(msg)
    print(content_type, chat_type, chat_id)

    if content_type == "text":
        bot.sendMessage(chat_id, msg["text"], reply_markup=keyboard)


MessageLoop(bot, handle).run_as_thread()
while 1:
    time.sleep(10)
