Here is the updated viersion:

files =et([file for file in glob.glob('Flag_of_*.svg')])
for file in files:
file =ile[8:-4]
if file.startswith('the_'):
file =ile[4:]
if countries.has_key(file):
b =flag-'+ countries[file] + '.svg'
print b
rename(file, b)
But I cannot get the rename to take effect and I get an error:
$ python rename_svg.py
Uganda flag-ug.svg
Traceback (most recent call last):
File "rename_svg.py", line 21, in <module>
rename(file, b)
OSError: [Errno 2] No such file or directory
What am I missing?

When I run this I get:
Flag_of_Uganda
...
The problem is that for example the file Flag_of_the_United_States.svg when I
use the strip('.svg') it is returned as Flag_of_the_United_State
Also, How do I remove 'Flag_of', 'Flag_of_the_'
I suggest you use glob.glob() instead of os.listdir():
files =lob.glob('Flag_of_*.svg)
Then you know that each file name starts with Flag_of_ and ends with
.svg. To remove them, since they are fixed strings you can just use
slicing;
file =ile[8:-4]
if file.startswith('the_'):
file =ile[4:]

(Please don't top-post on this mailing list. It hopelessly confuses which
order the quoted messages come.)
One reason the rename() will fail is that you're changing file between
the for loop and the rename. Incidentally, file is a lousy name to use,
since it already has a meaning in the std lib. It's the type of the
object you get from open(), or from glob.glog().
I didn't check the rest, but for this change, you'd get:
for infile in files:
country = infile[8:-4]
if country.startswith('the_'):
country = country[4:]
if countries.has_key(file):
b = 'flag-'+ countries[country] + '.svg'
print b
rename(file, b)
BTW, several other characters were dropped in your email. Did you
retype the code (bad), or use cut/paste?
