Get TypeError dict values object does not support indexing when using python 3 2 3

Question

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

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

In Python 3 the dict values   method returns a dictionary view object  not a list like it does in Python 2  Dictionary views have a length  can be iterated  and support membership testing  but don t support indexing   To make your code work in both versions  you could use either of these    names i  value for i value in enumerate d values        nbsp  nbsp  nbsp  nbsp or  values   list d values     name values i  for i name in enumerate names     By far the simplest  fastest way to do the same thing in either version would be   dict zip names  d values       Note however  that all of these methods will give you results that will vary depending on the actual contents of d  To overcome that  you may be able use an OrderedDict instead  which remembers the order that keys were first inserted into it  so you can count on the order of what is returned by the values   method

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
