How to download photos from Flickr by Flickr API in Python 3

noob question series...

I am a new learner of python, recently want to create a small python application that can collect photos from flickr based on different search input. (eg: if i input "dog", it will download all dog images from flickr)

I did some research online and notice that flickr API might be the best way and the method flickr.photos.getSizes should be the one I need to use.

However, I have few stupid questions when coding:

I have applied my key and secret for flickr API, I just don't know what to do next with flickr.photos.getSizes in python to download photos. Like, how to call this method in python? (and I noticed required arguments for this method are keys and photo_id, how to get photo_ids based on search input "dog")

Then I followed a tutorial from https://github.com/alexis-mignon/python-flickr-api/wiki/Tutorial but when I imported flickr_api I got error message:

Could not load all modules
<class 'ImportError'> No module named 'objects'
Traceback (most recent call last):
  File "D:/Agfa/Projects/Image/flickr.py", line 2, in <module>
    import flickr_api
  File "D:\Application\Anaconda3\lib\site-packages\flickr_api\__init__.py", line 32, in <module>
    from auth import set_auth_handler
ImportError: cannot import name 'set_auth_handler'

Then I took a look at the _ init _.py:

try:
    from objects import *
    import objects
    import upload as Upload
    from upload import upload, replace
except Exception as e:
    print "Could not load all modules"
    print type(e), e

from auth import set_auth_handler
from method_call import enable_cache, disable_cache
from keys import set_keys
from _version import __version__

Seems like this library does not support python 3 but I don't know what to do. (I cannot install methond_call, keys, _version on my python 3) guess I will use flickrapi

Thank you so much for your time and again thanks in advance.

Solution

I think I finally got the proper way to use FlickrAPI:

there are many ways but I figured out 2:

def flickr_walk(keyward):
    count = 0
    photos = flickr.walk(text=keyward,
                 tag_mode='all',
                 tags=keyward,
                 extras='url_c',
                 per_page=100)

    for photo in photos:
        try:
            url=photo.get('url_c')
            urllib.request.urlretrieve(url, path+'\\' + str(count) +".jpg")
        except Exception as e:
            print('failed to download image')

flickr.walk uses Photos.search API, I can use the API directly as well:

def flickr_search(keyward):
    obj = flickr.photos.search(text=keyward,
                           tags=keyward,
                           extras='url_c',
                           per_page=5)

    for photo in obj:
        url=photo.get('url_c')
        photos = ET.dump(obj)
        print (photos)

Remember to get the key and secret first:

api_key = 'xxxxxxxxxxxxxxxx'
api_secret = 'xxxxxxxxxxxxx'

flickr=flickrapi.FlickrAPI(api_key,api_secret,cache=True)
