Get the from a data:dict when you don't know the key in prior

Question

I want to get the key from a randomly given dict,

In [1]: d = {"unknown":1}                                                                                                     
In [2]: d.keys()                                                                                                              
Out[2]: dict_keys(['unknown'])
In [3]: k = [k for k in d.keys()][0]                                                                                          
In [4]: k                                                                                                                     
Out[4]: 'unknown'

The solution is cumbersome,

How could get it done in a succinct way?

Does "from a randomly" mean get a random key from the dictionary? — Silver, Mar 30 '19 at 07:08
You can store keys in a list and based on those key, ask for values. — NoobN3rd, Mar 30 '19 at 07:09
the dict is given in a random way, to get it first key@SilverSlash — Alice, Mar 30 '19 at 07:09
The dict name is given in a random way as well? I am a bit confused. — Yu Zhang, Mar 30 '19 at 07:12

What about list(d.keys()[0]) ?

Just use k = d.keys()[0] if the first key has to be fetched, because d.keys() itself returns a list.

At least try running your code before posting it as an asnwer... – Silver Mar 30 '19 at 07:11
it "works" in python 2. but there's no such thing as a first key. – Jean-François Fabre Mar 30 '19 at 07:14
According to the original question - it was for Python2.7. The edit was done after I answered it. – Mudra Mar 30 '19 at 07:15
