ENE 419 Computer Networks Assignment 1 -Solved

Programming Assignment (Application layer) 
You will create a chat-bot program that can collect Bit Coin prices from major exchanges and notify a user. 
Your program should be named as ‘coin-studentid.py’. It consists of following parts: 
A. Requesting Bit Coin (BTC) prices every starting minute exactly (e.g., 13:01:00, 13:02:00, and so 
on) via http request api from cryptocompare.com or similar services that you can find on your 
own. 
B. Sending message to you from your telegram chat-bot. 
C. Receiving command from your telegram chat-bot. 
**Part A. Request the following Bit Coin prices: Bitfinex (or else where that you like) in USD and EUR. 
Please refer to crytocompare api instruction for single or multi symbol(s) price: (if you want, you can use 
other similar api services, like Upbit or Bithumb for KRW price.)

To request data, please refer to the following instruction: 
http://docs.python-requests.org/en/master/user/quickstart/ 
Its request should be made every starting minute continuously. Please refer to the following instruction. 
You can find more APS scheduler examples on Google. Alternatively, you can use crontab or threading 
timer.

The collected information should be stored to csv file. It is similar to the following: 
$more price.csv 
Date, BTC-USD, BTC-EUR 
2021-08-30-00:00:00, 4567.8, 3000.0 
2021-08-30-00:01:00, 4572.7, 3000.0 
2021-08-30-00:02:00, 4582.7, 3000.0 
… 
**Part B. Send text message to your telegram using chat-bot. To do this, create your telegram chat-bot and 
send pricing up/down information every minute as well. 
Telegram chat-bot instruction: (please refer to BotFather) 
https://core.telegram.org/bots 
Recommended chat-bot api: 
http://telepot.readthedocs.io/en/latest/You need to create ‘TOKEN’ in order to send a message. You can do this manually for now. Read these 
instructions carefully. And your telegram chat window should be similar to the following (please ignore 
‘profit’ field in this example): 
**Part C. Add a “/stop” command if you want to stop receiving these messages. You don’t need “/start” 
button (you can assume that you can receive these messages when starting your program). This means you 
should be able to type “/stop” command in your telegram window and your program must receive this and 
act correspondingly. We can discuss this in class. 
NOTE: 
1. Python is recommended. If you are willing to use other programming languages, that’s fine too. 
But use it at your own risk. 
2. Any platform of your choice is fine, but I’d like to see many Linux as possible (e.g., Ubuntu). 
3. If you want, you can use Kakao Talk and others instead of telegram. 
SUBMISSION: 
 All followings should be in a single pdf file. Then submit to LMS. 
1. Your source code – “your-name.py” 
2. Screenshots of your telegram window (like the example above). 
3. Write one paragraph explaining your program and any difficulties you had.IMPORTANT: 
Do your best. Even if you can’t do the whole assignment, submit as much as you can (with explanation 
why you can’t do this). If you get caught cheating, I will deduct your other assignment marks. And to make 
sure that you do your own assignment, I will randomly select a few students in class and ask them to 
explain their code. 
TRIVIA: 
Google is your friend and teacher. Search! 
Discuss with your classmates! (DO NOT send me an email first) 
I will go over the assignment in class, so don’t worry too much.
