The operation items() will work for both 2 and 3, but in 2 it will return a list of the dictionary''s (key, value) pairs, which will not reflect changes to the dict that happen after the items() call.
If have enabled " Check for linked work items " as Required check on the target branch of PR, under the right Work items section of the PR Overview tab, you can see which work items are linked to the
for keyvalue in dict ems(): key, value = keyvalue[0], keyvalue[1] Remember that a for loop always iterates over the individual elements of the iterator you give it. dict ems() returns a list-like object of tuples, so every run
4 In python dict ems returns a list of tuples containing both the keys and the values of the dict. Javascript doesn''t have tuples, so it would have to be a nested array. If you''ll excuse me a little python code to show
I have a JavaScript array dataArray which I want to push into a new array newArray. Except I don''t want newArray[0] to be dataArray. I want to push in all the items into the new array: var newArra...
It returns a list of items (in python3 dict_items object), that you cannot assign them to two variable. If you want to separately get the keys and values you can use dict.keys() and dict.values() attributes:
So the items themselves are same -- the container delivering the items are different. One is a list, the other an iterator (depending on the Python version...) So the applicable differences between dict ems () and

Basically, the if condition ensures that foreach block will execute only if items is not null. I''m wondering if the if condition is really needed, or foreach will handle the case if items == null.
Also, since items returns a copy of the dictionary''s list of (key, value) pairs, it is less efficient, unless you want to create a copy anyway. In Python 2, it is best to use iteritems for iteration.
