+# Лабораторная 3: socket и requests
+
+## Подготовка окружения
+- python -m venv venv
+- venv\Scripts\activate (или source venv/bin/activate)
+- pip install requests
+
+## TCP/UDP серверы и клиенты
+- tcp_server.py / tcp_client.py — обмен строками по TCP на порту 10000
+- udp_server.py / udp_client.py — обмен строками по UDP на порту 10001
+
+## HTTP через socket
+- http_client_socket.py — GET / к vyatsu.ru через socket, порт 80
+
+## HTTP через requests
+- http_client_requests.py — GET к http://vyatsu.ru через библиотеку requests
+
+## Git API
+- git_api.py — запрос к https://git.vyatsu.ru/api/v1/user
+- Требуется переменная окружения GIT_VYATSU_TOKEN с токеном (read-only)
