End-To-End Example: European Country Locator

In this example, we will load in json data for European countries. We will write a program to prompt to input a country then tell the user which part of Europe the country is located in and what are the neighboring European countries.



In [ ]:

    
## todo list
# load europe data into Python
# loop
#   input a country name
#   if country name is quit, exit loop
#   for each country in europe
#        if input name equals country name
#              get info on country (region and neighbors)
#              print country info

# input: none
# output: Python object of data in JSON file

    with open('ETEE-europe.json', encoding='utf8') as f:
        data = f.read()
        europe = json.loads(data)
        return europe

# input: country and europe data
# output: dictionary of country info (name, region and neighbors)
def extract_country_info(country, europe):
    info = {}
    info['name'] = country['name']
    info['subregion'] = country['subregion']
    info['borders'] = []
    for country_code in country['borders']:
        for country in europe: 
            if country['alpha3Code'] == country_code:
                info['borders'].append(country['name'])
    return info

# main program 
europe = load_europe_data()
print("EUROPEAN COUNTRY LOCATOR")
while True:
    name = input("Enter a country name, or type 'quit': ").title()
    if name == 'Quit':

            print("%s is in %s.\nBordering countries are %s" % (info['name'], info['subregion'], info['borders']))
