I am not familiar with TIO. (And also with APL, I've used Q/KDB+ earlier, and they are somewhat similar.)
If I remember correctly assigning the function to a name is not part of the code
so I've added the assignment (f←) in the footer.
If that counts too, than it is 2 characters longer. (more) |

with lambda function it is little bit shorter
Instead of
def f(n,d):return
(19 chars with the space at the end)
You can write:
lambda n, d:
(11 chars)
As far as I know you don't need to assign it to a name, so it is a solution. (more) |

There are 8 kind of characters, " IXLCDM". 2 characters are 6 bits that can be easily mapped to printable characters (after 32 code point). This string is much shorter then the "DD DM IC ..." string itself. Even if I add the extraction it is still somewhat shorter.
I just regenerate the " IXLCDM" ... (more) |

Sorry for making that much work for you. My bad. I don't know exactly what did I do then but does't work for me now. But fortunately the current one is just 1 bytes longer.
It works if I use square brackets inside te max function, but then it is longer then the current one. (more) |

Thank you, At the end I have realized, that using 0,1 and 2 instead of the variables is even shorter. (more) |

Can I get the iterate function [from a 3rd party package](https://toolz.readthedocs.io/en/latest/api.html#toolz.itertoolz.iterate)? Then I can get a similar solution in Python.
Where can I find a detailed description of the rules? How to count imports, for example. (more) |
