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.items () and dict.iteritems () are the same as the applicable differences between a list and an iterator.
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.
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.
When you use the Work items and direct links type query, it can list all work items with directly links. It cannot display the linked work items that the sub child is connected to. For example: When you use the Tree of Work Items type query, it can list Parent/Child/sub child work item tree. But it only supports showing the Parent/Child link.
The align-items property of flex-box aligns the items inside a flex container along the cross axis just like justify-content does along the main axis. (For the default flex-direction: row the cross axis corresponds to vertical and the main axis corresponds to horizontal.
This can bring us convenience according to our usage habits. So, if we add the option for All Work items in the Work items screen, this will greatly increase the burden of Azure devops and make the response of Azure devops slow or even crash. That because work items serve the entire org, usually all work items will be a large number.
