Using the data you supplied as is, you could try something like:
def print_cities(filename):
# cnt is used just to know if it's time for a newline
cnt = 0
cities = open(filename,'r').readlines()
for city in cities:
# Make sure we have a valid population
if re.match('\d+$',city.split(',')[-1].strip()):
cnt += 1
c, p = city.split(',')
print "{:25} {:15,}".format(c.strip().replace('"',''),int(p.strip())),
if cnt % 2 == 0: print
Call it this way: print_cities('/path/to/Cities.txt'). The city names need to
be <= 25 characters in length and the numbers <= 15 characters in length
including commas but that would give you a number that is bigger than any city
I know of :-) You can adjust the column sizes as you wish and print the rest of
the letter formatted around the cities.
