How can I get the max value from specific key in nested dictionary

I have this dictionary and I want to get the max value of the ratio key only

I did this:

company_dict = {0: {'link': 'www.facebook.com', 'ratio': 0.91, 'size': 3},
                1: {'link': 'www.google.com', 'ratio': 0.92, 'size': 4}}
max_value = 0
for key, value in company_dict.items():
    for k, v in value.items():
        if k == 'ratio':
            if v > max_value:
                max_value = v

print(max_value)

Output:
0.92

Is there a better way ?

>Solution :

This also gives you the entire dictionary in addition to the max ratio:

best_company = max(company_dict.values(), key=lambda d: d["ratio"])
best_ratio = best_company["ratio"]
