Iterate a Nested Dictionary in Python

Question

My dictionary is structured as such:

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


        

Answer 1

This is what you want:

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

stock_sum = sum(stock_data[item]['total'] for item in stock_data)

for item in stock_data:
    stock_data[item]['percentage'] = int((float(stock_data[item]['total']) / stock_sum) * 100)

Result:

>>> for item in stock_data:
...     print stock_data[item]['percentage']
...
