Теперь запакуем строку.
В этом случае следует передавать тип данных bytes.
>>> struct.pack('=s', b'a')
b'a'
Для записи слова следует указывать количество символов.
>>> struct.pack('=5s', b'hello')
b'hello'
Кстати, запакованный вид соответствует исходному тексту. Всё верно, символ есть в таблице ASCII, то есть его код попадает в диапазон 0-127, он может быть записан одним байтом и имеет визуальное представление. А вот что будет если добавить символ вне ASCII
>>> struct.pack(f'=s', b'ё')
SyntaxError: bytes can only contain ASCII literal characters.
Ошибка возникла еще на этапе создания объекта bytes, который не может содержать такой символ. Поэтому надо кодировать эти байты из строки.
>>> enc = 'ёжик'.encode('utf-8')
>>> struct.pack(f'={len(enc)}s', enc)
b'\xd1\x91\xd0\xb6\xd0\xb8\xd0\xba'
Заметьте, длина такой строки в байтах отличается от исходной длины, так как символы вне ASCII записываются двумя байтами и более. Поэтому здесь формат создаём на лету, используя получившуюся длину как каунтер токена.

If you can afford it, you should definetly think about adding a pond to your homestead.
Although it might attract mosquitos during the summer (a counter-measure would be adding fish and frogs to eat the eggs), it improves the micro-biome drastically.
Bees will come and drink, as will birds. When birds have the possibility to drink, chances decrease that they will eat your fruit or berries, as they satisfy their need for hydration from the pond water.
The pond also is a nice temperature equalizer which is accepted by many other useful microfauna.

Plant Identification: A Practical Approach Using "Newcomb's Method"
Identifying plants using Newcomb's Method involves looking at the flower type, the plant/branching type, and the leaf type. This system uses a series of questions to guide you towards species identification. The questions are as follows:
For the flower type:
Is the flower regular (radially symmetrical - which means symmetrical in any way it can be divided across the center, like a sunflower) (most flowers fall into this category); or is the flower irregular (only symmetrical when divided one way, such as a mint or pea flower); or are the flower parts indistinguishable (too small to see)? If regular, how many petals or similar parts does it have?
For the plant/branching type:
Is the plant a wildflower, or a woody shrub or vine? If a wildflower, is it without leaves; or if it has leaves, are they all at the base of the plant (basal); or are they arranged singly on the stem (alternate); or are they opposite one another in pairs or whorls (whorled means many leaves coming off in different directions from the same area of the stem, like cleavers)?
For the leaf type:
Are the leaves entire (smooth-edged), or are they toothed, or lobed (split into sections), or divided (separated into leaflets off the same stem)?

Normal life Off Grid in Ireland.
The idea of living Off Grid can be very different to a lot of people. For some its a cabin in the woods, for others it may be a rustic Homestead in the American wilderness.
For us its just everyday modern life on our little property in the south east of Ireland.
