In Python versions before 3.7 dictionaries were inherently unordered, so what you're asking to do doesn't really make sense.
If you really, really know what you're doing, use
Copyvalue_at_index = list(dic.values())[index]
Bear in mind that prior to Python 3.7 adding or removing an element can potentially change the index of every other element.

Let us take an example of dictionary:
Copynumbers = {'first':0, 'second':1, 'third':3}
When I did
Copynumbers.values()[index]
I got an error:'dict_values' object does not support indexing
When I did
Copynumbers.itervalues()
to iterate and extract the values it is also giving an error:'dict' object has no attribute 'iteritems'
Hence I came up with new way of accessing dictionary elements by index just by converting them to tuples.
Copytuple(numbers.items())[key_index][value_index]
for example:
Copytuple(numbers.items())[0][0] gives 'first'
if u want to edit the values or sort the values the tuple object does not allow the item assignment. In this case you can use
Copylist(list(numbers.items())[index])

August 9, 2018How to get (first) element from list of dicts where dict key equals a specific value?
This will work: next(item["foo"] for item in my_dict if item["key"] == 3] Although if you're looking up several values this way, it will be more efficient to convert the whole thing to a simple dict of key to foo: better_dict = {item["key"]: item["foo"] for item in my_dict} Now you can just look up by key directly.

November 20, 2019Using get() with nested dictionary.
When get misses, the default return is None, which can't itself be "get"ed. You could have get give a different miss, like a dictionary, which could then give you further misses. I might do that for a single layer, but with a bunch, I would probably do something like create a function to do the search for me, probably recursively. edit: some great ideas here: https://stackoverflow.com/questions/25833613/safe-method-to-get-value-of-nested-dictionary Having never had the chance to use reduce, I would 100% use one of those solutions.

5. Data Structures — Python 3.14.6 documentation
The main operations on a dictionary are storing a value with some key and extracting the value given the key. It is also possible to delete a key:value pair with del. If you store using a key that is already in use, the old value associated with that key is forgotten. Extracting a value for a non-existent key by subscripting (d[key]) raises a KeyError. To avoid getting this error when trying to access a possibly non-existent key, use the get() method instead, which returns None (or a specified default value) if the key is not in the dictionary.

April 10, 2024 -
Hey all, hoping someone can help me out. I'm new to python but getting the hang of it. I'm using subprocess to run ffprobe and have it return JSON. Depending on the file I'm analyzing, some properties may not exist and won't appear in the JSON results. If i print this it works:
dvd_properties['streams'][0]['duration']
But I'm having trouble using the get() method on it:
dvd_properties.get('streams').get('0').get('duration'), "Unknown"
I'm trying to use get() so I have a default value if there are no results in the JSON output. I'm testing on a file that does have the duration element to make sure it works if I have data.
Can anyone lend me a hand? I've tried to search but I can't find anything about this particular situation. I have the get('parent').get('child') working for simple cases, so I'm hoping it will work here as well and I'm just missing something obvious.
Thanks in advance, I do appreciate it.

My guess here is you are failing on the get(0) command, because get is for dictionaries, but it looks like this value is a list. Try this: dvd_properties.get(‘streams’)[0].get(‘duration’) Now the issue is that it might fail when you hit the list part… you have some options though. I’d probably try doing the following: duration = ‘Unknown’ streams = dvd_properties.get(‘streams’) if streams and isinstance(streams, list): first_stream = streams[0] duration = first_stream.get(‘duration’) print(duration) You can also print the other variables along the way. Here is another option: try: duration = dvd_properties[‘streams’][0][‘duration’] except Exception: duration = ‘Unknown’ if not duration: duration = ‘Unknown’ Good luck!
