[Tutor] renaming files within a directory

[davidwilson at Safe-mail.net]

OK, I know that.

Here is what I have so far, but I get stuck on the mapping of the filename with the csv file.

>>> import os
>>> files = [file for file in os.listdir(os.getcwd()) if file.endswith('svg')]
>>> files
['Flag_of_Abkhazia.svg', 'Flag_of_Afghanistan.svg', 'Flag_of_Albania.svg', 'Flag_of_Algeria.svg', 'Flag_of_Andorra.svg', 'Flag_of_Angola.svg', 'Flag_of_Antigua_and_Barbuda.svg', 'Flag_of_Argentina.svg', 'Flag_of_Armenia.svg', 'Flag_of_Australia.svg']

>>> import csv
>>> reader = csv.reader(open("country.csv"))
>>> for row in reader:
...     print row   

['"km";"Comoros"']
['"dj";"Djibouti"']
['"er";"Eritrea"']
['"et";"Ethiopia"']
....

Here is where I am at.
Not sure how to map the two.

Dave
