В стандартном модуле random есть две очень похожие функции
random.randint()
random.randrange()
Обе возвращают случайное значение из указанного диапазона
>>> random.randint(10, 20)
12
>>> random.randrange(10, 20)
17
В чем же отличие?
Дело в том что у randrange() есть третий параметр step.
randint() действительно возвращает случайное число из указанного диапазона.
randrange() на первый взгляд делает тоже самое если передать также два параметра.
Но есть указать еще и step то наш диапазон усложняется, то есть в него попадёт не полный ряд значений.
Например, я хочу получить случайное значение из диапазона но только чётное число. Тогда достаточно сделать так:
>>> randrange(10, 20, 2)
16
Таким образом получается что randint это частный случай randrange без указания параметра step.
Еще одно важное отличие в том, что randint() включает в диапазон второе значение а randrange() нет. То есть выражение randrange(10, 20) никогда не вернёт 20, а randint(10, 20) вернёт.

🚘 Cybercab announced: Elon Musk’s robotaxi is finally here
📍 Tesla boss Elon Musk has unveiled the firm's long-awaited robotaxi, the Cybercab, at the Warner Bros Studios in Burbank, California.
🚕 The robotaxi is a purpose-built autonomous vehicle, lacking a steering wheel or pedals, meaning it will need approval from regulators before going into production. The design was futuristic, with doors that open upward like butterfly wings and a small cabin with only enough space for two passengers. There was no steering wheel or pedals, nor was there a plug — Musk said the vehicle charges inductively to regain power wirelessly.
🚐 In a surprise, the company also revealed a "robovan," a self-driving van capable of carrying up to 20 passengers or being configured for cargo purposes.
🪙 Musk said that autonomous cars are expected to be 10–20 times safer than human-driven vehicles and could cost as little as 20 cents per mile, compared to the $1 per mile for city buses.

New 🚘 electric cars will get Chinese autopilot
It will be developed by startup Momenta and will debut on the CLA electric sedan. The hardware will be based on Nvidia's Orin X chip.
The all-electric CLA will be equipped with a high-level intelligent driving system that does not rely on high-definition maps. This advanced system will provide navigation in the city, and mass production of the electric car is scheduled for April 2025.
Mercedes-Benz is one of Momenta's investors, along with GM and SAIC.

🚕Waymo robotaxis are back at the center of a scandal
📍 This time, the vehicles caused chaos on the streets of San Francisco.
🚥 The autonomous taxis use the traffic-light system for navigation, so when it goes down, route planning breaks as well.
⛔ For several hours, Waymo cars stood on the roads like bricks, blocking other drivers from getting through.
Is rise of the the machines beginning?

😰Three Waymo robotaxis caused a “standoff” and blocked a street in San Francisco
📰 In the northern part of San Francisco, three Waymo autonomous taxis got stuck on a narrow street, completely blocking traffic. Two cars lightly collided while trying to maneuver, after which both went into emergency mode, and the third stopped right in front of them, creating a full traffic jam.
😤 Because of this, residents couldn’t leave their driveways and had to wait for company engineers to intervene and resolve the situation. All vehicles were empty — no passengers were inside.
💬 Waymo commented on the incident, calling it a “learning moment” for improving their autonomous driving system.
