I have a program that require all keywords to be in a single paragraph, most of the time, separated by commas
For example:
I have those terms
1-Term
1.1-Term
2-Term
3-Term
4-Term
That i collected and organized into groups and subgroups with Titles and subtitles
Title
-
1-Term
-
1.1-Term
-
2-Term
- Sub-Title
- 3-Term
- 4-Term
- Sub-Title
But then i want to turn them into:
1-Term, 1.1-Term, 2-Term, 3-Term, 4-Term
Removing certain marked words(Titles and sub-Titles), any Empty/Blank space, and Line breaks, while adding the commas between The Terms. I want to keep certain dashes “-”(like in words )
1-Term,1.1 -Term,2-Term,3-Term,4-Term


If you can’t install a dedicated tool like
yqbut don’t mind creating a standalone script, python would be able to do this out of the box on pretty much any computer, calculator or toaster you can get your hands on in 2026:#! /usr/bin/env python3 import yaml import sys def parse_yaml(filename): with open(filename) as fd: return yaml.safe_load(fd) def get_leaf_nodes(data_iterable): output = [] for v in data_iterable: if isinstance(v, dict): output += get_leaf_nodes(v.values()) elif isinstance(v, list): output += get_leaf_nodes(v) else: output.append(v) return output print(",".join(get_leaf_nodes(parse_yaml(sys.argv[1]))))$ /tmp/foo.py /tmp/foo.txt Harry potter,Perfect Blue,Jurassic world,Jurassic Park,Jedi,Star wars,The clone wars,MCU,Gumball,Flapjack,Steven Universe,Stars vs. the forces of Evil,Wordgril,FlapjackThis takes the first argument on the command line, parses it as yaml, finds all leaf nodes recursively, and prints a comma-separated list of the results.
