I have a list of stock indexes (indizies) and several lists of stock tickers (eg gdaxi, mdaxi).
I want to download the stocks from yahoo in two loops.
Background: In the real program the user can choose which index, indexes he wants to download.
The problem is, that the type of index_name is a string and for the second loop index_name has to be a list. But the second loop takes index_name as a string.
Result:It trys to download the csv for g,d,a,x,i
Question: How can I transform index_name from string to list?
from pandas_datareader import data as pdr
indizies = ['GDAXI', 'MDAXI']
gdaxi = ["ADS.DE", "AIR.DE", "ALV.DE"]
mdaxi = ["AIXA.DE", "AT1.DE"]
for index_name in indizies:
for ticker in index_name:
df = pdr.get_data_yahoo(ticker)
df.to_csv(f'{ticker}.csv')
In ticker in index_name
you are iterating over the letters in given strings.
I guess you to change your code to something like:
from pandas_datareader import data as pdr
gdaxi = ["ADS.DE", "AIR.DE", "ALV.DE"]
mdaxi = ["AIXA.DE", "AT1.DE"]
indizies = [gdaxi, mdaxi]
for index_name in indizies:
for ticker in index_name:
df = pdr.get_data_yahoo(ticker)
df.to_csv(f'{ticker}.csv')```
