In Python 3.9.0 or greater we can merge dictionaries using `|`: d1 = {"name": "Alex", "age": 25} d2 = {"name": "Alex", "city": "New York"} merged_dict = d1 | d2

Is there an easy (and fast for large dictionaries) way to merge dictionaries in a way, that it includes every value of both dicts with the same key? for example, if d2 would include "name": "Luca" instead of "Alex", i would like the merged output to be like: {"name": ["Alex", "Luca"], "age": 25, "city": "New York"}

On the last tip it would be much faster to use a set instead of a list. Sets have constant lookup time but lists have O(n) lookup time.

@@sshishov True, but if you want to check membership, say, n times, than its O(n) vs. O(n**2). It depends on the problem which data structure is better, as your second comment shows. But if you are only worried about runtime, then @Evan Hagen is correct: you basically cannot lose by using a set (I mean even if you have to convert first), because if you run it once, it is the same runtime, but if you do it many times, then set is the better choice.

Tip 1 and 2: are there any advantages in terms of performance and/or memory management? As somebody who has to work with several programming languages and switch between them on the fly, I think I'd rather keep things as uniform and generic as possible between languages rather than stick to language specific idioms just for the sake of it.

@Leo3ABPgamingTV

@@jackgenewtf I think you missing my point about having to work with multiple programming languages, and basing your comment off an assumption that everybody else on the team is following python (or any language) specific idioms. My question was - are there any real practical (technical) benefit beyond the "we just used to do it that way" (i.e. language "idiom") and an overused "readability" argument. If people regularly work and switch between several different languages, having as uniform code structure as possible between all those languages seems like a more effective way to go, including the benefit for other team members who work with several languages as well or maybe simply not very experienced with python. Also, some people seem to be making a mistake by thinking that concise readable code is the same as cramming as much as possible into a single line. For example in a tip #2 of this video I would argue that a first shown method of filling a list is actually more readable and comprehensible than the second one, especially for people with limited or even no experience with python. Even for somebody not familiar with python syntax it would be more or less clear at a glance what happens in the code. Unfortunately same can not be said about a "correct" example featured in the tip.
@R3mak3r

Hey! The first tipp is really useful. Because it's a common issue - at least for beginners - using len for iterations. Because they use the lenght as an index instead of length - 1. So this method is readable and more secure because you cant use a non existent index. About the list comprehetions, ... I'm also not a fan, because I had trouble in the beginning to understand these. Plus I'm not a fan of long lines.
