The problem. Find all the countries in the world without an ‘A’ in their name.

1. Find a list of the world’s countries. [http://www.listofcountriesoftheworld.com(http://www.listofcountriesoftheworld.com)
2. Cut/paste the list to a file. countries.txt
3. Note the file is a list of numbers and names. Need to remove the numbers and filter out the ones without ‘A’s.

    def remove_country_line_numbers():
       return [l.strip() for l in  open('countries.txt').readlines() \
                    if not l.strip().isdigit() and l.lower().find('a')==-1]
   

Usage:

In [81]: ", ".join(remove_country_line_numbers())
Out[81]: "Belgium, Belize, Benin, Brunei, Burundi, Chile, Comoros, Congo, 
Republic of the, Cote d'Ivoire, Cyprus, Czech Republic, Djibouti, Egypt,
 Fiji, Greece, Guernsey, Hong Kong, Jersey, Lesotho, Liechtenstein, Luxembourg,
