# Python 100 project #4: Capital City Quiz -Which is city is further north?

I’m making some quiz as a preparation to deploy fun games on Alexa. This would be one of them. Game is quite simple to prompt two random capital cities, and you need to answer which city is further north than the other.

Output Example:

```shogokobayashi 100p \$ python3 capital_quiz.py

Do you want to try again? [Y]es or any other key to quit

Thank you for playing. You answered correctly 2 times out of 3 trials.
```

```import random

from data_source import countryinfo

def further_north():
capitals = countryinfo.capitals

city_lat = {}
for capital in capitals:
city, latitude = capital['CapitalName'], capital['CapitalLatitude']
if city != "N/A":
city_lat[city] = float(latitude)

trial, correct = 0, 0

while True:
trial += 1
city1, city2 = random.sample(city_lat.keys(), 2)

print(f"[Y]es or [N]o: City {city1} is further north than City {city2}.")
YesNo = ""
while YesNo not in ["y", "n"]:

if (YesNo == "y" and city_lat[city1] > city_lat[city2]) or (YesNo == "n" and city_lat[city1] < city_lat[city2]):
print("Correct!")
correct += 1

else:
print("Wrong.")

print("Do you want to try again? [Y]es or any other key to quit")
if input().lower() != "y":
break

print(f"Thank you for playing. You answered correctly {correct} times out of {trial} trials.")
