How to move random string to variable every second in python?

Question

Python

I am writing a python discord bot that displays a random line from a .txt file in response to a command. How can I loop a random string input into a variable?

The answer proposed by Sergey will most likely not work in the context of discord.py, as it will block the event loop every second. An asyncio solution is needed here.
In general, discord.py has a built-in tool for tasks: discord.ext.tasks

random_strings = ["abc", "bcd", "etc"]  # список строк, из файла/откуда угодно. Для чтения больших файлов может пригодиться https://github.com/Tinche/aiofiles
@tasks.loop(seconds=1)
async def update_text():
    text_variable = random.choice(random_strings)  # если список большой, возможно может понадобиться run_in_executor, но я в этом не уверен
