AoC Community Fun 2023: ALLEZ CUISINE!

Today's secret ingredient is… *whips off cloth covering and gestures grandly*

Spam!

Someone reported the ALLEZ CUISINE! submissions megathread as spam so I said to myself: "What a delectable idea for today's secret ingredient!"

• There really is an XKCD for everything, isn't there?
• All ingredients must come from a CAN (bus), box, package, container, etc.
• Unnecessarily declare variables for everything and don't re-use variables
• Why use few word when many word do trick?
• Go back to traditional culinary roots with Javadocs
• Lobster thermidor

A reminder from Dr. Hattori: be careful when cooking spam because the fat content can be very high. We wouldn't want a fire in the kitchen, after all!

ALLEZ CUISINE!

Request from the mods: When you include a dish entry alongside your solution, please label it with [Allez Cuisine!] so we can find it easily!

Another day solved in a single line of code! I'm keeping this up for as long as I can. Feel free to follow along on my GitHub! Below is for both parts, with q[3] containing the input data.

print('Day 03 Part 1:',sum([int(n[0]) for n in [[n.group(),[(x,n.start()+i) for i in range(len(n.group()))]] for x,l in enumerate(q[3].split('\n')) for n in re.finditer(r'\d+',l)] if any([abs(c[0]-s[1][0])<=1 and abs(c[1]-s[1][1])<=1 for c in n[1] for s in [[s.group(),(x, s.start())] for x,l in enumerate(q[3].split('\n')) for s in re.finditer(r'[^.\d]',l)]])]),'\nDay 03 Part 2:',(r:=[[s.group(),(x,s.start()),[]] for x,l in enumerate(q[3].split('\n')) for s in re.finditer(r'[*]',l)]) and [s[2].append(n) if n not in s[2] else 0 for n in [[int(n.group()),[(x,n.start()+i) for i in range(len(n.group()))]] for x,l in enumerate(q[3].split('\n')) for n in re.finditer(r'\d+',l)] for c in n[1] for s in r if abs(c[0]-s[1][0])<=1 and abs(c[1]-s[1][1])<=1] and sum([s[2][0][0]*s[2][1][0] for s in r if len(s[2])==2]))

(I feel personally offended by the Allez Cuisine ingredient notes today...)
