print('\n'.join(f'{i}. {n}' for i, n in enumerate(arr, 1)))

chunk_size = 3
arr = [ int(data[i:i + chunk_size]) for i in range(0, len(data), chunk_size) ]

Как это вообще работает?

Как мне при срезе включать последний элемент списка?

user = next((n for n in users if n['id'] == id), None)

[ f'{arr[i]} : {arr[i + 1]}' for i in range(0, len(arr), 2) ]

bs = ' '.join(n.upper() if n in cms else n for n in bs.split(' '))

for n in cms:
  if n in bs:
    bs = re.sub(f'\\b{n}\\b', n.upper(), bs)
