Determining the Percentage of Voter Population

[snippsat]

Some hints.
If i run the code,i can loop over data like this.

>>> for country in data:
...     print(country.name, country.population, country.voters)
... 
allegheny 1000490 645469
philadelphia 1134081 539069
montgomery 568952 399591
lancaster 345367 230278
delaware 414031 284538
chester 319919 230823

If eg make this function for percentage.

def percentage(voters, population):
    return 100 * voters / population

>>> for country in data:
...     print(country.name, percentage(country.voters, country.population))
... 
allegheny 64.51528750912053
philadelphia 47.53355359978696
montgomery 70.23281401594511
lancaster 66.67631823538439
delaware 68.72383951926305
chester 72.15045058280377
bucks 72.0064662984719

So this is stuff that you can have in highest_turnout function.
Now can try find highest voter percentage in the loop,or collect data and use max() if that allowed.
Place this function highest_turnout outside of class,not in the class as you have in first code.
Can place a function in class,as just a function with using @staticmethod.
