fin.close

Answer 1

# Python3

infname, outfname = 'cities.txt', 'squeeze.txt'

with open(infname, 'r') as fin, open(outfname, 'w') as fout:
    for line in fin.readlines():
        city, population, area, country = line.split()
        population, area = map(float, [population, area])
        density = population / area
        if density > 10000:
            fout.write(' '.join(map(str, [city, density, country])) + 'n')
