Here is the updated viersion:
---
import glob
import csv
from os import rename
countries = {}
reader = csv.reader(open("countries.csv"))
for row in reader:
code, name = row
countries[name] = code
files = set([file for file in glob.glob('Flag_of_*.svg')])
for file in files:
file = file[8:-4]
if file.startswith('the_'):
file = file[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?
