Binary and code plastered a lot One of the more generic ways of adding design to a code challenge site. The binary digits can be plastered around the header in a way that it looks cryptic. But bin...
Python 3, 183 181 175 bytes def f(a,b): c=a;a=str(a) for i in range(b): y=0;z=9 for j in range(len(a)): if y<int(a[j]):y=int(a[j]) if z>int(a[j]):z=int(a[j]) c=int(a)+...
Assign floats while leaving out zeroes Python allows such strange assignment. You can save bytes by removing the number preceding . if it's only 0: i=.5 print(i) Try it online! The same g...
Lua, 32 bytes print(string.reverse(io.read())) Try it online! Noice built-in.
Lua, 41 40 bytes x=0 y=1while""do print(x)x=x+y y=y+2 end Try it online!
Lua, 51 bytes P1: print("print(tonumber(io.read())+"..io.read()..")") Try it online! P2 (given I inputted 10, 29 bytes): print(tonumber(io.read())+10) Try it online!
Renaming functions A funny, cool, and useful trick. If you have to write a single function multiple times (usually range() on for loops), then you can simply assign a variable by the function's na...
Convenient whitespace removal Here are instances where you can remove whitespace: Strings If you assigned or printed a string, then the next supposed line of code can lean on the right double-qu...

I'm bored. Let's do something. lmao While I was Somewhere Else, I went to make suggestions for designs on their sites, and no impact really occured. However, since I'm now a Codidactian (not a Cod...
Use lambdas instead of functions At most times, lambdas tend to make smaller code, which is helpful in golfing. Assigning a lambda is easy, just do: lambda f:whatever There are many answers th...
import* You can import some libraries and if you find yourself using: from lib import * Remove the space between import and *, because it works for whatever reason.
Combine conditionals Python has its fair share of comparison operators and can actually be used in a single conditional. For example: x == 2 and y == 2 can be: x==y==2 Used on Make $2 + 2 ...
Replace for loops with string multiplication Let's say we have: for i in range(6):print(end="#") Try it online! This basically outputs # 6 times, which is self-explanatory in the code itsel...
jq --null-input --raw-output, 15 bytes "Hello, World!" Try it online! They kept saying that jq is the language of September 2021. Still surprised no one even made a Hello, World! on it.
Challenge Make a program that takes input of an integer that's $n > 1$ and print out a staircase using a specific character for stair basing (hashes (#) for demonstration; you can use spaces,...
Remove print's parentheses when it's a single string print strangely works without parentheses, however, it only applies to single strings. In other words, it can't do the same for other variables...
