从字典创建变量的最佳方法是什么

Question

To be able to increase my dictionary while not changing much else in the code, I want to iterate through the dictionary keys and create dataframes.

The way I have found is through creating global variables with global(). However, is this the most pythonic way, or the best way? I know global variables are a nono, but it seems to be the only fix here.

stocks = {
    'Tencent':'TCEHY',
    'Blizzard' : 'ATVI',
    'EA':'EA',
    'Rockstar':'TTWO'
}

def create_dataframes(stock_dict):
    for stock in stock_dict:
        globals()[stock] = pd.read_csv('{}.csv'.format(stock_dict[stock]))

This results in new variables with the key names, which is of course what I want. I just want to know if I should do this in another way?

Thanks!

Don't create global variables at runtime, just use a dictionary.

dfs = {}
for stock_name, stock_code in stock_dict.items():
    dfs[stock_name] = pd.read_csv(f'{stock_code}.csv')

You can then access them using their names

dfs['EA'].describe()
