Get: TypeError: 'dict_values' object does not support indexing when using python 3.2.3 [duplicate]

This is my code:

{names[i]:d.values()[i] for i in range(len(names))}

This works completely fine when using python 2.7.3; however, when I use python 3.2.3, I get an error stating 'dict_values' object does not support indexing. How can I modify the code to make it compatible for 3.2.3?


In Python 3, dict.values() (along with dict.keys() and dict.items()) returns a view, rather than a list. See the documentation here. You therefore need to wrap your call to dict.values() in a call to list like so:

v = list(d.values())
{names[i]:v[i] for i in range(len(names))}

A simpler version of your code would be:

dict(zip(names, d.values()))

If you want to keep the same structure, you can change it to:

vlst = list(d.values())
{names[i]: vlst[i] for i in range(len(names))}

(You can just as easily put list(d.values()) inside the comprehension instead of vlst; it's just wasteful to do so since it would be re-generating the list every time).
