I am collecting tweets using a Python script and I want to store them in a MongoDB database. I want to find out the lowest tweet id and for each tweet, I want to change the id field to an _id field.Is it possible not having to iterate over all the tweets with a for loop in order to do these 2 things.search_result = #search result from Twitter APImin_id = float('inf')result = []for tweet in search_result:    if tweet['id'] < min_id:        min_id = tweet['id']    tweet['_id'] = tweet.pop('id')    result.append(tweet)
Changing the id field to an _id field for the lowest tweet id

Three parts to your questions: 1) find lowest tweet ID and 2) assign id: to _id 3) can (1) and (2) be done without iterating over the list.To answer (3) first, (1) definitely can be done without iteration, but I am unaware of how to do (2) without iteration.(1) Lowest Tweet IDThe sort function is great for this. This question has more on sorting. To create a new list with the lowest id in the first position:results = sorted(search_results, key=lambda x: x.id)To do the same thing replacing the list:search_results.sort(search_results, key=lambda x: x.id)Simply access the 0th result in the list and you have your lowest tweet id.2) Assign id: to _idPerhaps someone can answer this better, but the best way I know of is how you've done it:for tweet in search_results:    tweet['_id'] = tweet.pop('id')Your final code would look something like:search_result = #search result from Twitter APIresults = sorted(search_results, key=lambda x: x.id)min_id = results[0]['id']for tweet in search_results:    tweet['_id'] = tweet.pop('id')
