How to convert list of tuples to multiple lists?
...nction zip() will almost do what you want:

Remove by _id in MongoDB console
...
Very close. This will work:
db.test_users.deleteOne( {"_id": ObjectId("4d512b45cc9374271b02ec4f")});
i.e. you don't need a new for the ObjectId.
Also, note that in some drivers/tools, remove() is now deprecated and deleteOne or deleteMany should be used instead.

target=“_blank” vs. target=“_new”

That means that there is no such keyword as _new in HTML5, and not in HTML4 (and consequently XHTML) either. That means, that there will be no consistent behavior whatsoever if you use this as a value for the target attribute.
