here I have a plug.
It is clear that I am doing everything wrong. but how should it be? where to read? What should I add to this code to make it work? Useful, I think it will be all

How to read from a file? Python
Help me figure it out or throw a lesson where about it?
in the main lesson how to read and display. I don't need a conclusion.
I need the word to be taken from the file and substituted into the blacklist construction
There are about 1000 words to block.
So the search must be made fast

I think that you need to write something blacklist=[' '] here, but I can understand the line-by-line principle of
inputfile operation - we turned to the
open file, opened it and read
further what?
how to make it so that if the word in the blacklist was removed from the message or the entire message?

inputfile = '1.txt'
open(inputfile, mode='r', encoding='utf-8')
blacklist=[' what?']

@bot.message_handler(content_types=["text"])
def handle_text( message):
for x in blacklist:
if (x in message.text):
bot.delete_message(message.chat.id, message.message_id)
else:
pass

if __name__ == "__main__":
bot.infinity_polling()

Please help me understand how this all works line by line

There are many answers to this question on the Internet, I will try to explain it very simply ..
You have a blacklist.txt file:

with open(f'blacklist.txt', encoding = "utf-8") as f:
  lines = f.read()
if message.text.lower() in lines:
  print("Слово из ЧС")
