[Python] How would you simplify this useless overcomplicated one-line function? for fun...

Disclaimer: This is just a pet project for fun and for programming practice


Long ago I wanted to make a random name generator, I originally made it in shell script so I could learn the language better, but I recently decided to try and convert it to python for funsies.

The premise is we start with a random character, and randomly choose the next character from a list of characters that typically occur after the current character, nothing super fancy at all. I was pretty happy with the output, it makes very "fantasy-like" names, like Zox, Gadimoa, or Zojitene for example.

Anyway, the bash script was about 80 ~ish lines, but when I simplified it to python, I got it down to just this:

import random
import string

next_char = {...} # Large dictionary of character associations, check the bottom for full thing.

def name_generator():
name = ''
for idx in range( -1, int((random.randint(1,9) * 0.7) + 3) - 1 ):
name += random.choice( next_char.get( name[idx:], string.ascii_lowercase ) )
return name


I don't know about you but when I see a small for loop like that, I get the itch to see if it can be a one liner.

I'm rambling so I'll save you the details, 7 iterations later and I have this monstrosity:

And here it is as a one line lambda for completeness, coming in at a whopping 1709 characters!

To use it, just copy it into python and run it, if you don't give it a value it should print "Fryia" which is the name for seed=0, to get randomness you must supply it with a random value for "i".

My Question:


How would you make this even more pointlessly compact, self-contained, or efficient?

My goals were to make it self contained, no modules or anything, but it could go further. For instance you could figure out how to remove the range call, or figure out how to get rid of all the duplication of the PRNG calculations.

Good luck! I'll mark an answer eventually based on reception.


Base character association dictionary for if you want to edit it and make it your own:

default_next_char = {
'a': 'abcdefghijklmnopqrstuvwxyz',
'b': 'aeiloru',
'c': 'aehikloruyz',
'd': 'aeijoruy',
'e': 'abcdefghijklmnpqrstvwxyz',
'f': 'aeiloru',
'g': 'aehiloruy',
'h': 'aeiouy',
'i': 'abcdefgjklmnopqrstvwz',
'j': 'aeiou',
'k': 'aeilnoruy',
'l': 'aeilou',
'm': 'aeiouy',
'n': 'aeiou',
'o': 'abcdefghijklmnopqrstuvwxyz',
