│ │ └── NYSE_symbols.csv
│ ├── excel
│ └── json

Setup:

clone application: git clone https://github.com/Larz60p/PySymbol

With internet access update environment: pip install -r requirements.txt
From PySymbol directory, run application to get current symbol files: python src/PySymbol.py

To import class in an application: see example: src/TrySymbolFetch.py

To force updates, instantiate sym as: sym = PySymbol.PySymbol(force_update=True)

To run interactively:

>>> import PySymbol
>>> sym = PySymbol.PySymbol()
>>> lookup = sym.Lookup
>>> lookup('NYSE', company_name='Raytheon Company')
'RTN'
>>> lookup('NYSE', ticker='RTN')
'Raytheon Company'
>>>

This class can be expanded by adding market information links in module: StkMktPaths.py
there is a dictionary named self.symbols, each market entry looks like:

'NASDAQ': {
                'url': 'https://old.nasdaq.com/screening/companies-by-name.' \
                    'aspx?letter=0&exchange=nasdaq&render=download',
                'filename': self.csvpath / 'NASDAQ_symbols.csv',
                'json_filename': self.jsonpath / 'NASDAQ_symbols.json',
                'dictname': self.dicts['NASDAQ'],
                'companies': {},
                'symbols': {}

            },

attributes:
url -- download url for markets symbol list (looking for csv file)
filename -- a pathlib path to save csv download
json_filename -- a pathlib path to save generated json file
dictname -- Name to be assigned to this market's information dictionary
companies -- placeholder for generated company dictionary
symbols -- placeholder for generated symbol information

the json file contains a lot of other information that you may find useful.
What's here depends on the source of the downloaded file, but for those in the package, contains (one cell):

"2362": {
        "Symbol": "RMAX",
        "Name": "RE/MAX Holdings, Inc.",
        "LastSale": "37.7",
        "MarketCap": "$1.15B",
        "IPOyear": "2013",
        "Sector": "Finance",
        "industry": "Real Estate",
        "Summary Quote": "https://old.nasdaq.com/symbol/rmax",

    },

There's a problem with the PyPi version. Git clone is OK, I'll post when corrected.
