How can I iterate through and extract values from the following list, the code I am using below only gets the key values.
> [{'filename': <docxtpl.InlineImage object at 0x040038D0>, 'desc':
> u'dfgdgfdfg'}, {'filename': <docxtpl.InlineImage object at
> 0x04014930>, 'desc': u'dfgdfgdfg'}, {'filename': <docxtpl.InlineImage
> object at 0x04014A90>, 'desc': u'fghfghfh'}]
Code:
for k,v in audit_items_list:
print audit_items_list
print k
print v
If I use k.value(). I get the following error :
AttributeError: 'str' object has no attribute 'values'
Update: Thanks for all the help, but i actually want to grab the values of filename and desc on each iteration...

The outer item is a list, and the inner items are dictionaries. You just need to go one level deeper.
for audit_item in audit_items_list:
for k, v in audit_item.items():
# iterate over key value pairs.
# Or get the entire list of each by doing item.keys() or item.values()
Use audit_items_list.items() if you are using Python 3 or audit_items_list.iteritems() if you are using Python 2.
for tdict in audit_items_list: # To iterate over all dictionaries present in the list
# print tdict
for key in tdict: # To iterate over all the keys in current dictionary
# print key
print tdict[key] # To get the value corresponding to that key
Clearly, this is a list of dictionaries where every dictionary has one key-value pair.
for item in audit_items_list:
(key, val) = item.items()
print(key,value)
Hope this helps!
