Not thoroughly tested but here is the one with even more capabilities … Python v3.x with yfinance, lxml, logging, and gzip libraries will be needed to work which will create prices.csv in current directory.
# --- Start of script ---
from lxml import etree
import logging
import gzip
import sys
import yfinance as yf
onlyMultiple = True
createQuotes = False
if len(sys.argv) > 3:
if "quotes" in sys.argv[3].lower():
createQuotes = True
if len(sys.argv) > 2:
if "all" in sys.argv[2].lower():
onlyMultiple = False
if len(sys.argv) > 1:
data_file = sys.argv[1]
else:
print ("\nProvide one or two positional parameters:")
print (" Required first argument: GNC data file.")
print (" Required second argument: 'all' to display all tickers, not just those with multiple namespaces; else any non blank string.")
print (" Optional third argument: 'quotes' to create an importable 'prices.csv' file.\n")
exit()
namespaces = dict()
logger = logging.getLogger("yfinance")
logger.disabled = True
logger.propagate = False
try:
with gzip.open(data_file, "rb") as f:
context = etree.iterparse(f, tag='{http://www.gnucash.org/XML/gnc}commodity')
for event, elem in context:
symbol = elem[1].text
namespace = elem[0].text
elem.clear()
if symbol in namespaces:
namespaces[symbol] = namespaces[symbol] + ", " +namespace
else:
namespaces[symbol] = namespace
with open("prices.csv", "w", encoding="utf-8") as file:
if not file.writable():
createQuotes = False
for ticker in sorted(namespaces.keys()):
if onlyMultiple:
if namespaces[ticker].count(",") > 0:
print ("{}:{}".format(ticker, namespaces[ticker]))
else:
print ("{}:{}".format(ticker, namespaces[ticker]))
namespace = namespaces[ticker].split(",")[0]
if namespace != "CURRENCY" and createQuotes:
try:
quotes = yf.Ticker(ticker)
info = quotes.info
prices = quotes.history(period="1wk", auto_adjust=True)
if not prices.empty:
currency = "USD"
prices.reset_index(inplace=True)
prices['Date'] = prices['Date'].dt.strftime('%m/%d/%Y')
prices.drop(['Dividends','Stock Splits'], inplace=True, axis=1)
prices.to_dict(orient='records')
infoAttr = info.keys()
if 'financialCurrency' in infoAttr:
currency = info['financialCurrency']
if 'currency' in infoAttr:
currency = info['currency']
for i in prices.index:
close = prices['Close'][i]
date = prices['Date'][i]
high = prices['High'][i]
low = prices['Low'][i]
volume = prices['Volume'][i]/100
with open("prices.csv", "a", encoding="utf-8") as file:
file.write('"{}","{}","{}",{},"{}"\n'.format(namespace, ticker, date, close, currency))
except Exception as e:
pass

Well, I guess I was able to goad the sleepyhead to up his game! ;)
Thanks for the upgrade!

David – yeah I think the guy that wrote the script was probably sleep deprived when he did it 😊 …. here is the one that meets new requirements as well as a bit more 😊.
Since spacing matters in Python, attached one should fully run if saved as a file.

Kalpesh,
It is nice to see how a user could use Python to get at this information, but it seems to me that having to supply a list of symbols to the script defeats the point of trying to find those symbols that have secondary namespaces.
I wonder whether there is a Python analog for "find all securities that are not currencies" that Wm provided in his SQL...

Script attached in-case spaces gets munged up by the list server which I already show done so.

Here is the Python script that will do so. You'll need to provide full path to your compressed XML data file as the first argument, followed by list of symbols to find namespace(s) for. All parameters separated by one or more spaces.
Example
c:\CloudDrives\OneDrive\QuickenStuff\HELPERS>python display_namespaces.py c:\data\gnucash\example.gnucash NANC NANC:CBOE NANC:CBOE - US
You will need Python 3.X installed, along with lxml and gzip libraries installed in Python for the script to work. You would copy & paste everything between '# ---' delimiters to a file for a fully running script.
Now you have both ways to do it. Hope these helps.
# --- Start of Script
from lxml import etree
import gzip
import sys
if len(sys.argv) > 2:
tickers = [ticker.strip() for ticker in sys.argv[2:]]
data_file = sys.argv[1]
else:
print ("\nProvide two positional parameters:")
print (" File name as the first.")
print (" Specify one or more tickers as second and onward separated by a space.")
exit()
with gzip.open(data_file, "rb") as f:
context = etree.iterparse(f, tag='{http://www.gnucash.org/XML/gnc}commodity')
for event, elem in context:
symbol = elem[1].text
namespace = elem[0].text
elem.clear()
if any(symbol.lower() == ticker.lower() for ticker in tickers):
print ("{}:{}".format(symbol, namespace)) # --- End of Script

I don't think you can do it in gnc but here is some SQL that does it
_____
with m_cnt as (
select mnemonic, count(*) as cnt
from commodities
group by mnemonic
having cnt > 1
)
select namespace, mnemonic
from commodities
where mnemonic in (select mnemonic from m_cnt)
;
