Instead of constructing the data string by hand, you can pass a 
dictionary or list of 2-item tuples to urllib.urlencode() and get a 
properly formatted string:

my_data = urllib.urlencode({'Amount':1,'From':'EUR','To':'USD'}) # or...
my_data = urllib.urlencode([('Amount',1),('From','EUR'),('To','USD')])
a = urllib.urlopen('http://www.suckerservice.com/convert.cgi', my_data)
