Hi all,
Seemingly simple problem:
There is a case in my code where I know a dictionary has only one item in it. I
want to get the value of that item, whatever the key is.
In Python2 I'd write:
>>> d = {"Wilf's Cafe": 1}
>>> d.values()[0]
1
and that'd be an end to it.
In Python 3:
>>> d = {"Wilf's Cafe": 1}
>>> d.values()[0]
Traceback (most recent call last):
File "<input>", line 1, in <module>
TypeError: 'dict_values' object does not support indexing
"Wilf's Cafe"
>>> d[list(d)[0]]
1
>>> for k in d:
... value = d[k]
... break
...
>>> value
1
>>> list(d.values())[0]
1
None of this feels like the "one, and preferably only one, obvious way to do
it" we all strive for. Any other ideas?
Thanks,
Nick
