i want to check a value exist in my nested python dictionary.my dictionary is

dic = {'sample': {'a': 'hi', 'callback': 'foo'}}

I want to check the "callback" key of nested dictionary is exist or not in this dic. The key 'sample' can vary so we can't check like dic['sample'] .There will be only one key in the outer dic

So, what exactly is the logic? Is there only one key in the outer dict? Or may there be multiple? Is it always exactly one key, or perhaps zero? – deceze Feb 15 '21 at 07:30
there will be only one key in the outer dic and the value will vary – Pratheesh Feb 15 '21 at 07:32
`'callback' in next(iter(dic.values()))`…? – deceze Feb 15 '21 at 07:35
Perfect..That is working – Pratheesh Feb 15 '21 at 07:37
