From text to ascii art from CodinGame practice puzzle

3

On CodingGame, there is a Puzzle that ask to write words with ascii art. I solve the puzzle then tried to golf it. What improvement can I do on it?

2(j+1) can be -~j. The space between ] and for can be omitted. – Arnauld – 2019-12-23T17:27:54.397

1c.isalpha()*(ord(c)-91)+26 is shorter than the if. – manatwork – 2019-12-23T18:35:33.533

Is ? the only non-alphabetic character? – Jonathan Allan – 2019-12-23T18:38:44.297

1@JonathanAllan, that seems to be the joker to replace any non-alphabetic character, like in tr --complement 'A-Z' '?'. – manatwork – 2019-12-23T18:40:02.270

@JonathanAllan yes. If a character is non-alphabetic, it's ASCII art must be the '?' art. – Dorian Turba – 2019-12-23T21:21:37.630

@DorianTurba for one less byte total, we we can multiply by l inside the comprehension assigned to t (which is just l*, once we use an indexing lookup rather than an if-else) and use r[j-l:j] :) – Jonathan Allan – 2019-12-23T23:00:55.553

Yes, I see that in your answer. I remove the comment, thanks. – Dorian Turba – 2019-12-23T23:12:09.093

Is it allowed for the program to terminate with error after printing due to trying to read a line past the last line? – xnor – 2019-12-24T06:07:09.103

@xnor I don't know. You can try the code in the puzzle link provided in my question, the tests are in there. – Dorian Turba – 2019-12-24T06:09:47.933

Python 3,  131 130 128 126  125 bytes

i=input
L=int(i())
exec("t=[L*[27,ord(c)%32][c.isalpha()]for c in i()]"+";r=i();print(''.join(r[j-L:j]for j in t))"*int(i()))

A few golfs of the provided code.

Note: I upper-cased l to L and replaced a couple of ; with newlines just for legibility.

Try it online!

  1. When characters are alphabetical their ordinals are ranges \$[65,90]+[97,122]\$ which modulo \$32\$ are \$[1,27]+[1,27]=[1,27]\$. As such we can remove the .upper() and work with ord(c)%32 in this case.
  2. Rather than an if-else we can either use the fact that False is 0 and True is 1 and multiply (as originally suggested by manatwork in comments) or use list indexing for the two cases like above ([27,ord(c)%32][c.isalpha()] chooses the slice stop rather than its start).
  3. We can save a little by replacing the while loop with the exec of a string of code produced using string multiplication.
  4. We can save a byte by moving t=... into the exec-ed code so we do not have to assign to h at all. Another is saved by moving the repeated string's trailing ; to the beginning so that the t assignment string doesn't require its own.
  5. Rather than [(j-1)*L:j*L], or even [~-j*L:j*L], we can multiply by L once in the construction of t and just do [j-L:j].

The oneliner is just for the fun to have few bytes and lines, it's totally ok if it does not increase the number of bytes. – Dorian Turba – 2019-12-23T21:46:41.350

The explanation of your code is great, thank you a lot for this helpful answer. I'll wait a few days before accepting. – Dorian Turba – 2019-12-23T21:48:11.797
