why not use sqlite?

Looking at

german-nouns/german_nouns/lookup/__init__.py

Lines 35 to 68 in 1d076f5

	def create_index(self) -> None:
	print('Creating index once')
	# create index
	col_index_to_skip = {1, 2, 3, 4, 5, 6} # everything before "pos" and after the last "genus" column
	for row_idx, row in enumerate(self.data):
	for col_idx, word in enumerate(row):
	if col_idx in col_index_to_skip:
	continue
	if not word:
	continue
	word_low = word.lower()
	if row_idx not in self.index[word_low]:
	# liste, weil Reihenfolge der Indexes erhalten bleiben muss
	self.index[word_low].append(row_idx)
	# save index file
	output = ''
	for k, v in self.index.items():
	indexes = '\t'.join(str(x) for x in v)
	output += f'{k}\t{indexes}\n'
	with open(INDEX_FILE_PATH, 'w', encoding='utf-8') as f:
	f.write(output)
	def load_index(self) -> None:
	with open(INDEX_FILE_PATH, encoding='utf8') as f:
	lines = [l.strip() for l in f.readlines()]
	for line in lines:
	split = line.split('\t')
	word_low = split[0]
	self.index[word_low] = [int(x) for x in split[1:] if x]

this logic screams for just writing import sqlite3 (comes with the python interpreter!), creating a table in memory (or on disk), maybe even with a column index, and writing some simple sql queries.
