For each from list insert item in mongo collection

I have a list of ids arr = [123, 456, 765...]

I need to do a for each of these:

I need to run a bunch of steps like grabbing some values from a MongoDB collection, then converting that into a list, and then making a change to the returned fields and inserting them back to a new collection.

How do I do this for a forEach of the id's in that list.

Here is the rest of functions I am running:

hello=col.find({'id':123}, {'_id':0})

for item in hello:
   to_ISO = datetime.strptime(item['created_dt'], "%Y-%m-%dT%H:%M:%S.%f%z")  

   list_audits = list(audit_pages_res)
   pprint(list_audits)

db.newcol.insert({date: to_ISO})

I want to do a forEach from arr, replace the id in hello do the rest of the functions I need and then insert the record and then move to the next item on the list.

Is there any way for me to do that?

Hard to figure out exactly what you're trying to do but if you know the exact _id then no need to use a find and a loop; just use find_one(). start with:

arr = [123, 456, 765]

for arr_id in arr:
    hello=col.find_one({'id':arr_id}, {'_id':0})

    if hello is not None: # Need to check it found a record
        to_ISO = datetime.strptime(hello['created_dt'], "%Y-%m-%dT%H:%M:%S.%f%z")
