This collaboration will benefit both companies massively, but most importantly, the users, especially Apple users. Gemini is powerful, and it will enable Apple Intelligence to compete with other competitors that offer better functionalities.

[News from Google @NewsFromGoogle]

Joint Statement: Apple and Google have entered into a multi-year collaboration under which the next generation of Apple Foundation Models will be based on Google's Gemini models and cloud technology. These models will help power future Apple Intelligence features, including a more personalized Siri coming this year.

After careful evaluation, Apple determined that Google's Al technology provides the most capable foundation for Apple Foundation Models and is excited about the innovative new experiences it will unlock for Apple users. Apple Intelligence will continue to run on Apple devices and Private Cloud Compute, while maintaining Apple's industry-leading privacy standards.

Chained #Comparisons in #Python #Programming 🐍

How to check if a value is between a range?

The variable/function gets executed only once when using chained comparisons, compared to twice when using the "and" operator.

Reversing #Lists in #Python #Programming 🐍

Q: How can we reverse the order of items in a list without changing the original variable?
A: Slicing [::-1]

If the step value has a negative sign, it moves backward from the end toward the beginning.
