With yet another week down, this time bringing with it a newly-found Animal Crossing glitch, a super gorgeous Super Mario 64 PC port, and all sorts of interesting stats from Nintendo’s fiscal year earnings report, it’s finally time to sit back and enjoy the weekend.

Members of Team Nintendo Life have gathered together to discuss our weekend plans, and we’d love for you to join in via our poll and comment sections below. Enjoy!

Alex Olney, senior video producer

It’s a lovely long bank holiday weekend in the rather infected United Kingdom, and in absence of being able to do anything outside of these four walls, some friends and I will be mashing out some games on Realm Royale. Bit of an odd choice, granted, but one of my friends is a tight git and there aren’t many other (vaguely) Halo-like experiences on Switch right now.

After all the shooting and drinking and the weekend begins proper, I’ll be having a right ruddy good time with Lonely Mountains: Downhill, so I’ll no doubt bash a bit of that out as well, not to mention some patented Super Smash Bros. Ultimate for good measure.

Aside from that, phwoar, I’m really not sure. I’ve been working on creating a classically-styled world in Super Mario Maker 2 which I’m keen to crack on with, but at the same time Animal Crossing is so just bloody there.

Ryan Craddock, news editor

Yesterday, I finally paid off the last-but-one loan in Animal Crossing: New Horizons, meaning I can finally start to properly organise the rooms in my house. I have fairly big plans for the bigger rooms, but seeing the prices of some of the items I want to put in them is rather terrifying. It doesn’t help that I’m not playing the game quite as much as I was at launch, either, as I’m starting to save a little less money in-game with each passing week.

As I mentioned last week, I’ve also been spending a little more time trying to beat Resident Evil 4 on Wii. Every time I feel like I must be near the end, another huge chunk of the map opens up. It really does feel like I’m nearing the end this time, though, so hopefully I’ll soon be able to check this one off my embarrassingly long list of shame.

PJ O’Reilly, reviewer

This weekend I’m gonna be continuing to mess around with two absolute crackers that I’ve had the pleasure of reviewing on Switch over the past week, Awesome Studio’s Fury Unleashed and Blue Manchu’s Void Bastards. They’re both roguelikes that really couldn’t be more different in terms of mechanics and tone – one’s a bright and anarchic Dead Cells style platformer, the other a wonderfully unique and grimy first-person space shooter – but they do share a cool comic book aesthetic that’s deployed to excellent effect in both games.

Elsewhere I’ll be continuing to experiment with the latest Super Mario Maker 2 update, dying repeatedly at the hands of my son’s bewildering creations and finally actually getting to grips with Deadly Premonition Origins, a game I’ve been meaning to play for absolutely ages. Have a good weekend, everyone, and stay safe.

Gavin Lane, features editor

I’ve heard very good things about Void Bastards and wouldn’t mind checking that out this weekend, but I got Galak-Z: The Void on sale a couple of weeks back and it’s still sitting untouched on my Switch. I’ve also got the excellent Streets of Rage 4 to finish, plus a dozen other things I should dip into before splashing more cash on the eShop. Plus, I’ll need to swing by the Able Sisters’ shop to make sure I don’t miss out the latest fashion. I’m on the bleeding edge of the fashion scene, me – the toast of Milan! Paris! And er, other places where they wear… clothes.

Oh, it’s been a long week, okay? Have a good one, everyone.

Gonçalo Lopes, contributing writer

Now that I have the world’s biggest live gig stage it is time to build a wrestling ring in Animal Crossing: New Horizons. Streets of Rage 4 continues to entertain but I can’t ignore a slew of great content being dropped on the eShop: Gun Crazy, ITTA, 80’s Overdrive, Slayin 2, Void Bastards, Lonely Mountains: Downhill, Fury Unleashed, Jay & Silent Bob: Mall Brawl and Task Force Kampas. Not all fun and games, mind. I am also working on the often requested review of Space Invaders: Invincible Collection for you fine folks.

My game of the week is Trials of Mana. The real trial was actually getting a copy of the game, but I eventually managed to secure one from Germany. Fear not, Ich spreche sehr gut Deutsch.

As always, thanks for reading! Make sure to leave a vote in the poll above and a comment below with your gaming choices over the next few days…

For some time now, there have been concerns about what Nintendo has planned for the Switch in the immediate future. After Xenoblade Chronicles: Definitive Edition arrives at the end of this month, there’s Clubhouse Games: 51 Worldwide Classics in June, followed by some DLC for Pokémon Sword and Shield and Super Smash Bros. Ultimate.

There’s no need to worry, according to Nintendo president Shuntaro Furukawa. At the company’s recent investor’s Q&A, he mentioned how the Japanese video game giant had other games planned for this period but said it had become “increasingly difficult” to follow the current schedule due to the current restrictions in place.

For our forecast, we have games that are scheduled to release during this period other than what’s been announced. However, many workers at Nintendo and our partners are working from home during this time. Considering the working environments between home and office are quite different, it could become increasingly difficult to release our games in line with our current schedule if the situation is prolonged. As things currently stand, we’re forecasting as if we’ll be able to release our games according to schedule.

We already know about projects like Metroid Prime 4, and the sequel to The Legend of Zelda: Breath of the Wild, but what do you think we could see released this year? Perhaps we might finally see something like Bayonetta 3 or how about the rumoured Super Mario remasters? Share your own thoughts below.

Short answer: To filter a list of lists for a condition on the inner lists, use the list comprehension statement [x for x in list if condition(x)] and replace condition(x) with your filtering condition that returns True to include inner list x, and False otherwise.

Lists belong to the most important data structures in Python—every master coder knows them by heart! Surprisingly, even intermediate coders don’t know the best way to filter a list—let alone a list of lists in Python. This tutorial shows you how to do the latter!

Problem: Say, you’ve got a list of lists. You want to filter the list of lists so that only those inner lists remain that satisfy a certain condition. The condition is a function of the inner list—such as the average or sum of the inner list elements.

Example: Given the following list of lists with weekly temperature measurements per week—and one inner list per week.

# Measurements of a temperature sensor (7 per week)

temperature = [[10, 8, 9, 12, 13, 7, 8], # week 1 [9, 9, 5, 6, 6, 9, 11], # week 2 [10, 8, 8, 5, 6, 3, 1]] # week 3

How to filter out the colder weeks with average temperature value <8? This is the output you desire:

print(cold_weeks)

# [[9, 9, 5, 6, 6, 9, 11], [10, 8, 8, 5, 6, 3, 1]]

There are two semantically equivalent methods to achieve this: list comprehension and the map() function. Let’s explore both variants next.

If you’re short on time, you can also get a quick overview by playing with the code in your web browser—I’ll explain the code after that.

Method 1: List Comprehension

The most Pythonic way of filtering a list—in my opinion—is the list comprehension statement [x for x in list if condition]. You can replace condition with any function of x you would like to use as a filtering condition. Only elements that are in the list and meet the condition are included in the newly created list.

Solution: Here’s how you can solve the above problem to filter a list of lists based on a function of the inner lists:

# Measurements of a temperature sensor (7 per week)

temperature = [[10, 8, 9, 12, 13, 7, 8], # week 1 [9, 9, 5, 6, 6, 9, 11], # week 2 [10, 8, 8, 5, 6, 3, 1]] # week 3 # How to filter weeks with average temperature <8? # Method 1: List Comprehension

cold_weeks = [x for x in temperature if sum(x)/len(x)<8]

print(cold_weeks)

# [[9, 9, 5, 6, 6, 9, 11], [10, 8, 8, 5, 6, 3, 1]]

The second and third list in the list of lists meet the condition of having an average temperature of less than 8 degrees. So those are included in the variable cold_weeks.

You can visualize the memory usage of this code snippet in the following interactive tool:

This is the most efficient way of filtering a list and it’s also the most Pythonic one. If you look for alternatives though, keep reading.

Method 2: Filter() Function

The filter(function, iterable) function takes a function as input that takes on argument (a list element) and returns a Boolean value that indicates whether this list element should pass the filter. All elements that pass the filter are returned as a new iterable object (a filter object).

You can use the lambda function statement to create the function right where you pass it as an argument. The syntax of the lambda function is lambda x: expression and it means that you use x as an input argument and you return expression as a result (that can or cannot use x to decide about the return value). For more information, see my detailed blog article about the lambda function.

# Measurements of a temperature sensor (7 per week)

temperature = [[10, 8, 9, 12, 13, 7, 8], # week 1 [9, 9, 5, 6, 6, 9, 11], # week 2 [10, 8, 8, 5, 6, 3, 1]] # week 3 # How to filter weeks with average temperature <8? # Method 2: Map()

cold_weeks = list(filter(lambda x: sum(x) / len(x) < 8, temperature))

print(cold_weeks)

# [[9, 9, 5, 6, 6, 9, 11], [10, 8, 8, 5, 6, 3, 1]]

Again, the second and third list in the list of lists meet the condition of having an average temperature of less than 8 degrees. So those are included in the variable cold_weeks.

The filter() function returns a filter object that’s an iterable. To convert it to a list, you use the list(...) constructor.
