如何让我的 Python 脚本无限运行（循环）？

Question

I am building a Telegram bot that tells me the price of Bitcoin in USD whenever I send the bot a "/price" command on Telegram. It works, however the price does not update unless I re-run the Python script. How can I keep the script running forever so that I do not need to constantly click "run"? Here is my code:

import requests
import telebot


# BITCOIN DATA
url = 'https://api.coinbase.com/v2/prices/USD/spot?'
response = requests.get(url).json()



# BOT STUFF
bot = telebot.TeleBot("1135809125:AAHHx7sZ5276Kg34VWYDuwHIJB76s5QS9UQ")


@bot.message_handler(commands=['price'])
def send_welcome(message):
    bot.reply_to(message, "The current price of Bitcoin in USD is " + response['data'][0]['amount'])


@bot.message_handler(func=lambda message: True)
def echo_all(message):
    bot.reply_to(message, message.text)


bot.polling()

Answer 1

Maybe try with itertools :

import itertools
for x in itertools.repeat(1):
    bot.polling()

Or itertools.count() :

import itertools
for elt in itertools.count():
    bot.polling()

Or according to link , you can try this:

if __name__ == '__main__':
     bot.polling(none_stop=True)

Answer 2

response should be inside send_welcome to get the current price everytime you send a /price command.

    @bot.message_handler(commands=['price'])
    def send_welcome(message):
        response = requests.get(url).json()
        bot.reply_to(message, "The current price of Bitcoin in USD is " + response['data'][0]['amount'])

Answer 3

Use a while loop:

import requests
import telebot

# BITCOIN DATA
url = 'https://api.coinbase.com/v2/prices/USD/spot?'
response = requests.get(url).json()



# BOT STUFF
bot = telebot.TeleBot("1135809125:AAHHx7sZ5276Kg34VWYDuwHIJB76s5QS9UQ")


@bot.message_handler(commands=['price'])
def send_welcome(message):
    bot.reply_to(message, "The current price of Bitcoin in USD is " + response['data'][0]['amount'])


@bot.message_handler(func=lambda message: True)
def echo_all(message):
    bot.reply_to(message, message.text)

while True:

    bot.polling()
