Here at Nintendo Life we’ve been anticipating the release of zany physics-based battler Fight Crab for a while now – over two years, in fact. Today publisher and developer Mastiff and partner Calappa Games have announced that the 3D crustacean-based scrapper will be arriving on Switch eShop on 15th September in North America, Europe, and Australia.

The announcement comes with a new preview trailer which you can enjoy above. If you’ve forgotten the general premise of this crazy crab battler, it involves taking control of a crab and engaging in deadly combat against other creatures using a variety of weaponry, including a whip sword, nunchaku, an axe gun, a chainsaw, and even lightsabers (sorry, “Beam Sabers”).

Allow us to refresh your memory with details and some key features from the PR blurb and a few screenshots:

– Claw through 7 Tutorial stages and a Campaign Mode with 34 stages spread out across 7 chapters
– 23 types of playable crab, 48 different weapons, and 11 unique battle arenas
– A variety of matchmaking options including 1 vs. 1, 2 vs. 2, and both offline and online co-op and versus battle modes
– Unlock special Skills like the fabled Kanihameha, the devastating Crab Copter, and more
– Level up your crab, recruit new crabs, and purchase deadly new weapons – build the ultimate crab warrior
– Use the Nintendo Switch Joy-Con™ motion controls to freely manipulate limbs to punch, grab, and flip your way to victory
– Use Photo Mode to capture, share, and immortalize epic confrontations and intense battles

No word on pricing just yet, but we’ll update this article when we hear how much this delicious crab meat will cost.

Looking forward to unleashing some massive damage as ol’ Snipper here? Let us know below.

Python is powerful — you can condense many algorithms into a single line of Python code. So the natural question arises: can you write a while loop in a single line of code? This article explores this mission-critical question in all detail.

How to Write a While Loop in a Single Line of Python Code?

There are three ways of writing a one-liner while loop:

• Method 1: If the loop body consists of one statement, write this statement into the same line: while True: print('hi'). This prints the string 'hi' to the shell for as long as you don’t interfere or your operating system forcefully terminates the execution.
• Method 2: If the loop body consists of multiple statements, use the semicolon to separate them: while True: print('hi'), print('bye'). This runs the statements one after the other within the while loop.
• Method 3: If the loop body consists nested compound statements, replace the inner compound structures with the ternary operator: while True: print('hi') if condition else print('bye').

Exercise: Run the code. What do you observe? Try to fix the infinite loop!

Next, you’ll dive deep into each of these methods and become a better coder in the process.

Before we move on, I’m excited to present you my brand-new Python book Python One-Liners (Amazon Link).

If you like one-liners, you’ll LOVE the book. It’ll teach you everything there is to know about a single line of Python code. But it’s also an introduction to computer science, data science, machine learning, and algorithms. The universe in a single line of Python!

The book is released in 2020 with the world-class programming book publisher NoStarch Press (San Francisco).

But enough promo, let’s dive into the first method—the profane…

Method 1: Single-Statement While Loop One-Liner

Just writing the while loop into a single line of code is the most direct way of accomplishing the task. Say, you want to write the following infinite while loop in a single line of code:

while True: print('hi') '''

hi

hi

... '''

You can easily get this done by writing the command in a single line of code:

# Method 1: Single-Line While Loop

while True: print('hi')

While this answer seems straightforward, the interesting question is: can we write a more complex while loop that has a longer loop body in a single line?

Let’s explore an alternative Python trick that’s very popular among Python masters:

Method 2: Multi-Statement While Loop One-Liner

As it turns out, you can also use the semicolon to separate multiple independent statements and express them in a single line. The statement expression1; expression2 reads “first execute expression1, then execute expression2“.

Here’s an example how you can run a while loop until a counter variable c reaches the threshold c == 10:

c = 0

while c < 10: print©; c = c + 1 '''

0

1

2

3

4

5

6

7

8

9 '''

This way, you can easily compress “flat” loop bodies in a single line of Python code.

But what if the loop body is not flat but nested in a hierarchical manner—how to express those nested while loops in a single line?

Method 3: Nested Compound Statements While Loop One-Liner

You often want to use compound statements in Python that are statements that require an indented block such as if statements or while loops.

In the previous methods, you’ve seen simple while loop one-liners with one loop body statement, as well as multiple semicolon-separated loop body statements.

Problem: But what if you want to use a compound statement within a simple while loop—in a single line of code?

Example: The following statement works just fine:

# YES:

if expression: print('hi')

You can also add multiple statements like this:

# YES:

if expression: print('hi'); print('ho')

But you cannot use nested compound statements in a while loop one-liner:

# NO:

while expression1: if expression2: print('hi')

Python throws an error does not work because both the while and if statements are compound.

However, there’s an easy fix to make this work. You can replace the if expression2: print('hi') part with a ternary operator and use an expression rather than a compound statement:

# Method 3: One-Line While Loop + Ternary Operator

while True: print('yes') if True else print('no')

You can also use nested ternary operators to account for possibly nested if blocks:
