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.

Scientists found a new drug, SW033291, that protects the brain’s blood barrier by blocking an enzyme called 15-PGDH. This stops brain damage and memory loss in mice with Alzheimer’s and brain injuries. Unlike other drugs, it does not remove amyloid protein but still keeps the brain safe and working well. The drug worked even when given a day after injury.🧠💊

Learning another language may slow brain aging, according to a huge new study. Multilingual people show less cognitive decline compared to those who speak only one language. The study suggests that speaking multiple languages helps keep brain networks active, especially those responsible for memory and attention, protecting the brain from aging effects.

Some studies found that watching a lot of (internet)pornography can change the brain. Brain scans showed stronger links in areas that control emotions and decisions. People who watch often feel more pleasure but have less self-control. After watching, their thinking and attention get worse. Their facial expressions also show less emotion, like surprise or disgust, even if they say they enjoyed it. These changes are similar to drug addiction. Repeating this behavior can make emotional responses dull and reduce mental sharpness.
More research is needed, but finding people who never watched porn for studies is very difficult to impossible..
