Question: I got a query result in array `Array ( [0] => stdClass Object ( [model] => Peugeot 308 SW ) [1] => stdClass Object ( [model] => Citroen C-Elysee ) [2] => stdClass Object ( [model] => Nissan Evalia ) [3] => stdClass Object ( [model] => Renault Trafic 9-os ) )`

And I want to make a single variable for every object like:

$Peugeot 308 SW  

$Citroen C-Elysee  

$Nissan Evalia

But I don't know how to do that. Thank you

Answer: 
You do not need to call `d.keys()`, so

```
if key not in d:
    d[key] = value

```

is enough. There is no clearer, more readable method.

You could update again with `dict.get()`, which would return an existing value if the key is already present:

```
d[key] = d.get(key, value)

```

but I strongly recommend against this; this is code golfing, hindering maintenance and readability.
Use [`dict.setdefault()`](https://docs.python.org/3/library/stdtypes.html#dict.setdefault):

```
>>> d = {'key1': 'one'}
>>> d.setdefault('key1', 'some-unused-value')
'one'
>>> d    # d has not changed because the key already existed
{'key1': 'one'}
>>> d.setdefault('key2', 'two')
'two'
>>> d
{'key1': 'one', 'key2': 'two'}

```
