Первая директория в sys.path
🔸 Когда вы запускаете Python-интерпретатор в интерактивном режиме, в системные пути (sys.path) в самое начало добавляется текущая рабочая директория
>>> for path in sys.path:
... print(f'"{path}"')
""
"/usr/lib/python37.zip"
"/usr/lib/python3.7"
...
Первая строка пустая, что и означает текущую рабочую директорию.
🔸 Если вы запускаете интерпретатор передавая скрипт как аргумент, то история получается иная. На первом месте будет директория в которой располагается скрипт. А текущая рабочая директория игнорируется.
Пишем скрипт с таким содержанием:
# script.py
import sys
for path in sys.path:
print(f'"{path}"')
Запускаем
python3 /home/user/dev/script.py
Получаем
"/home/user/dev"
"/usr/lib/python37.zip"
"/usr/lib/python3.7"
...
🔸 Если вы запускаете скрипт по имени модуля то на первом месте будет домашняя директория текущего юзера
python3 -m script
"/home/user"
"/usr/lib/python37.zip"
"/usr/lib/python3.7"
...
Скрипт должен быть доступен для импорта
На что это влияет?
На видимость модулей для импорта. Если вы ждёте, что, запустив скрипт по пути, сможете импортировать модули из текущей рабочей директории, то вы ошибаетесь. Придётся добавлять путь os.getcwd() в sys.path самостоятельно или заранее объявлять переменную PYTHONPATH.

The US government has revealed a list of items Americans should keep on hand in case of an emergency.
Officials warned that households should be prepared to survive on their own for several days if disaster strikes, with no immediate access to outside help.
The Department of Homeland Security recommends storing enough water, food, and medical supplies to sustain every person in a household during an extended emergency.
At the top of the list is water, at least one gallon per person per day, along with several days' worth of non-perishable food. Americans are also urged to keep critical safety items such as flashlights, radios, batteries, and first-aid kits readily available in a portable emergency supply kit.
Officials said the supplies should be stored in airtight containers and kept in easy-to-carry bins or bags in case families need to evacuate quickly.
The checklist also includes tools to signal for help, sanitation supplies, and equipment to shelter safely indoors if conditions outside become dangerous.
While the Trump administration has not urged Americans to stockpile large quantities of supplies, federal officials and preparedness experts recommend keeping essential items on hand in case of an emergency.
