问题
I am having issues with my below class. I keep getting the below traceback, butI am not sure were I am going wrong. I am expecting to see a dictionary with photo tags. Any help would be great.
Traceback:
File "project.py", line 231, in <module>
new_photo = Photo(result_get_photo_data)
File "project.py", line 228, in __init__
for diction in photo_diction["photo"]["tags"]["tag"]:
TypeError: list indices must be integers, not st
My Code:
class Photo(object):
def __init__(self,photo_diction):
self.tags = []
for diction in photo_diction["photo"]["tags"]["tag"]:
return self.tags.append(diction)
new_photo = Photo(result_get_photo_data)
print new_photo.tags
Some Contents of Photo Diction, its a list that contains several dictionaries.

I see two issues here.
Your photo_dictation is a list. You need either:
for dictation in photo_diction[0]["photo"]["tags"]["tag"]:or a double loop:
for photo in photo_dictation: for dictation in photo["photo"]["tags"]["tag"]you are returning within your loop. I think you probably want:
class Photo(object): def __init__(self,photo_diction): self.tags = [] for diction in photo_diction["photo"]["tags"]["tag"]: self.tags.append(diction) return
