mojito - The First Attempt (2022.04.27)

mojito ; a wrapper module for OPEN API including KIS Developers

• Very convenient!

Installation

$ pip install mojito2

mojitoTest.py

import mojito
import pprint
import Key

# print(mojito.__version__)                                         # test : ok

key = Key.key
secret = Key.secret

broker = mojito.KoreaInvestment(api_key=key, api_secret=secret)
resp = broker.fetch_price("005930")
# pprint.pprint(resp)                                               # success; full data in json
print(resp['output']['stck_prpr'])                                  # success

※ Caution

Don't name the file as mojito.py that causes an error like the below (☞ see) :

AttributeError: partially initialized module 'mojito' has no attribute 'KoreaInvestment' (most likely due to a circular import)

Inquire Price (2022.04.26)

Call a specific stock's current price and daily price-related data
※ Need to improve not to call the API access token more than once
