Just increment and decrement... Iloveunicorns (talk) 10:55, 16 September 2025 (UTC)


WHO CAN WRITE SHORTEST INTERPRETER???

i=p=0;c=input()+" "
for x in c:exec({"I":"i+=1","l":"i-=1"}.get(x,"i")+";p+=1")if c[p+1:]!=""else print(i)

tried my best

By abstracting the summation and using a dispatch dictionary which builds intermediate integers instead of code snippets, we can write a single-stage function:
lambda s:sum({"I":1,"l":-1}[c] for c in s)
Some of the existing interpreters don't care about invalid inputs. If invalid inputs or comments are a serious concern then we can use the .get() method of dictionaries:
lambda s:sum({"I":1,"l":-1}.get(c,0) for c in s)
We can apply directly to input() for a one-liner that can be invoked with python3 -c:
print(sum({"I":1,"l":-1}.get(c,0) for c in input()))
This doesn't appear to get shorter when using map() or the functools or operator modules, although I invite golfers to keep trying. The secret insight is that Il admits a monoid! Corbin (talk) 15:53, 17 September 2025 (UTC)
