StockListing 함수 직접 만들기 (22년 1월 이후 FinanceDataReader의 StockListing 함수 결과값이 달라짐) 강의편에서 크롤링 함수 오류가 납니다.

알려주신대로,

def StockListing() :

import requests

import pandas as pd

import json

try :

from pandas import json_normalize

except importError:

from pandas.io.json import json_normalize

data = {'bld':'dbms/comm/finder/finder_stkisu', 'locale':'ko_KR',}

r = requests.post('http://data.krx.co.kr/comm/bldAttendant/getjsondata.cmd', data=data)

jo = json.loads(r.text)

df = json_normalize(jo,'block1')

df_info = df[['short_code', 'codeName']]

df_info.columns = ['Symbol','Name']

return df_info

df = StockListing()

    356         return obj, end

JSONDecodeError: Expecting value: line 16 column 3 (char 36)

이런 오류가 나는데, 어떻게 해결해야 할까요?

pip install -U finance-datareader

import FinanceDataReader as fdr
print(fdr.__version__)

import pandas as pd

# KRX 상장 기업 목록 (코자존이 올려둔 GitHub 백업 데이터)
df_krx = pd.read_csv("https://raw.githubusercontent.com/corazzon/finance-data-analysis/main/krx.csv")

# 확인
print(df_krx.head())
