Accessing dict_keys element by index in Python3

Question

I\'m trying to access a dict_key\'s element by its index:

test = {\'foo\': \'bar\', \'hello\': \'world\'}
keys = test.keys()  # dict_keys object

keys.index(         


        

Answer 1

Call list() on the dictionary instead:

keys = list(test)

In Python 3, the dict.keys() method returns a dictionary view object, which acts as a set. Iterating over the dictionary directly also yields keys, so turning a dictionary into a list results in a list of all the keys:

>>> test = {'foo': 'bar', 'hello': 'world'}
>>> list(test)
['foo', 'hello']
>>> list(test)[0]
'foo'
