A Steem price watching bot written in Python!

4년 전

My bot is named Steempy, and "he" will monitor the steem price 6 times a minute and if the price changes he will print out the difference in the console.

Steempy is still in version 0.0.2 and has a few bugs, like the change in price not displaying in a "pretty" way but, the logic behind Steempy is correct. That bug is the only one I could find so far! So give it a test and let me know what you think!

If you have any experience with displaying floats/decimals in Python in a pretty way, please comment your suggestions bellow. I tried the decimal module but, it didn't seem to help a whole lot.


Now for the code: Steempy.py:

# Steempy: a bot that monitors a CryptoCompare API  v0.0.2
# Bugs: having trouble with like 19 & line 24 displaying the change
# correctly.  Example: displays 2.0E-7 as a change.

from decimal import Decimal
import requests
import time
url = "https://min-api.cryptocompare.com/data/histominute?fsym=STEEM&tsym=BTC&limit=1&aggregate=0&e=CCCAGG"
coin_price = [0.0000001]
while True:
	minutechart = requests.get(url).json()
	print("Sleeping...")
	time.sleep(5)
	# list indexing from multiple nested lists/dicts
	a = minutechart['Data'][-1]['close']
	coin_price.append(a)
	b = coin_price[0]
	if a > b:
		diff = Decimal(a) - Decimal(b)
		print("a higher difference of {} BTC since last price".format(
					round(Decimal(diff),8)))
		coin_price.pop(0)
		print(a)
	elif a < b:
		diff = Decimal(b) - Decimal(a)
		print("a lower difference of {} BTC since last price".format(
					round(Decimal(diff),8)))
		coin_price.pop(0)
	else:
		coin_price.pop(0)
		print("Current Price: {} ".format(coin_price))

Nice, I'd really like to get into writing some scripts to interface with Steem (and steemit). I know a fair bit of JavaScript but my python is still lacking. I think I should just give it a try and learn by practice. Thanks for your post,

You're welcome, I've only been writing with python for about 1.5 months. It's actually not too hard to pick up. I really want to start working with the steem blockchain and steemits Python libraries. If your interested, I would check out this github: https://github.com/steemit/steem-python It has alot of the tools you'll need to work with steemit. I just haven't got around to working with it yet. When I do though, I'll be sure to upload some code of the projects that I put together! Thanks for the comment by the way. Engaging with my followers always keeps me motivated.
