Iterate a Nested Dictionary in Python

Question

My dictionary is structured as such:

stockData = {
    \'AAPL\': {
        \'beta\': 1.01833975315094,
        \'company_name\': \'Apple\',
        \'dividend\':         


        

Answer 1

If I understand you question correctly, you may try as follows (I just copied the stockData below):

stockData = {
    'AAPL': {
        'beta': 1.01833975315094,
        'company_name': 'Apple',
        'dividend': 1.9341673320912078, 'total': 300},
    'GOOG': {
        'beta': 1.01833975315094,
        'company_name': 'Apple',
        'dividend': 1.9341673320912078, 'total': 300}}

I guess this is what you meant:

def get_portfolio_value(stocks, item='total'):
     portValue = 0
     for v in stocks.values():
        portValue += v[item]
     for k in stocks.keys():
        stocks[k].update({'percentage': stocks[k]['total'] / portValue})
    print(portValue)

get_portfolio_value(stockData, 'total')
