It seems that MKD30015 not working since 20200917 about pykrx

[mr-yoo]

MKD30015 can be called directly as follows:

from pykrx.website.krx.market.core import MKD30015

df = MKD30015().fetch(date="20200916", market="ALL")
df.head()

It is recommended to use stock.get_market_cap_by_ticker as a user-friendly API.

from pykrx import stock
df = stock.get_market_cap_by_ticker(date="20200916", market="ALL")

In my environment, the API prints out the correct results. If you attach the code you wrote, I will check it in detail.

[mr-yoo]

In the current version, the business day of the stock market should be passed by variable date of the API.

[mr-yoo]

targetDayStr="20200917"
print(stock.get_market_ticker_list("20200921"))
dfTargetDay = stock.get_market_cap_by_ticker(targetDayStr)
if (dfTargetDay.empty):
print('targetDay empty. day: ' + targetDayStr)

It seems to be a version problem or a module dependency problem. Please check PYKRX version first.

import pykrx
print(pykrx.__version__)

If the version is lower than 0.1.41, upgrade to the latest version.
pip install -U pykrx

If the latest version does not fix the problem, please attach a list of installed modules that you see as a result of pip freeze.

The code works well in a virtual environment made from a list of modules you provide.

$ python --version
Python 3.7.6

$ virtualenv venv
$ source venv/Script/activate
venv $ pip intall -r requirement.txt

I will check the code with the latest Python (version 3.8.4). If it goes well, I think you'd better reinstall Python.

[mr-yoo]

It operates normally in the pure python 3.8.4 and the latest Anaconda (3.8.3).

• I tested the codes with python 3.8.4 on https://repl.it/languages/python3 website and with anaconda on my desktop.

I don't think there's anything I can help with given information.
