[SOLVED] Download file with urlretrieve() to subfolder

Download file with urlretrieve() to subfolder

Is it possible to use urlretrieve() in order to download something into a subfolder without expressing it in an absolute but relative manner? For example:

urllib.request.urlretrieve(url, '/downloads/2017/foo.txt')

Everytime I add a path to the filename python throws following error:

File "C:\Program Files\Python36\lib\urllib\request.py", line 258, in urlretrieve tfp = open(filename, 'wb') FileNotFoundError: [Errno 2] No such file or directory: '/downloads/2017/foo.txt'

But when I use this code:

urllib.request.urlretrieve(url, 'foo.txt')

it happily downloads the file.

I think I am missing something basic here, but after searching the interwebs for quite a while I haven't found an answer yet. Does anyone know how relative filepaths should be expressed in the urlretrieve() method?

Solution

When using urllib.request.urlretrieve(), you need to make sure that, if you want to save the file somewhere else than the program's location, the folders you are referencing already exist. Alternatively you can use the following code to generate the folders you need if they do not exist:

for i in directories:
    if not os.path.isdir(i):
        os.makedirs(i)

Check for spelling mistakes if you still get a FileNotFoundError.
