Python yfinance: Fehlgeschlagene Downloads - "Keine Daten gefunden, Symbol kann gelöst werden" ⇐ Python

[Anonymous]

Ich versuche nur, historische Schlusspreise für bestimmte Ticker herunterzuladen, die in einer .csv -Datei gefunden wurden. Ich habe jedoch Probleme damit, dass YFInance aus irgendeinem bizarren Grund die Daten abzieht. Ich habe eine andere Datei, die auf die gleiche Weise zu funktionieren scheint und mir die Daten fehlerfrei gibt, die ich auch einbeziehen werde. Was könnte den Fehler verursachen, den ich empfange? kann so sauber ausgeführt werden, während die Verwendung von .csv zu einem Fehler ohne verfügbare Daten führt. >

Code: Select all

import pandas as pd
import yfinance as yf
from datetime import datetime

today = datetime.today().strftime('%Y-%m-%d')

tickers = pd.read_csv("Hardware.csv")
tickers = tickers["Symbol"].to_list()
print(tickers)

df = yf.download(tickers,'2022-1-1',today, auto_adjust=True)['Close']
print(df.head())

Original Arbeitscode:

Code: Select all

import yfinance as yf
import pandas as pd
from datetime import datetime

today = datetime.today().strftime('%Y-%m-%d')

# Read and print the stock tickers that make up S&P500
tickers = pd.read_html(
'https://en.wikipedia.org/wiki/List_of_S%26P_500_companies')[0]
print(tickers.head())

# Get the data for this tickers from yahoo finance
df = yf.download(tickers.Symbol.to_list(),'2022-1-1',today, auto_adjust=True)['Close']
print(df.head())
