💬 Discussion: "Python models: the pandas problem (and a possible solution)"LimitationsPython models have capabilities that SQL models do not. They also have some drawbacks compared to SQL models:Time and cost. Python models are slower to run than SQL models, and the cloud resources that...

This type of assignment helps you create accumulators and counter variables, for example. Therefore, it’s quite a common task in programming. As in many similar cases, Python offers a more convenient solution. It supports a shorthand syntax called augmented assignment:...
Common optimization paradigms used in these contexts include simulated annealing—a method inspired by the controlled cooling process of metals, which iteratively improves a solution while occasionally accepting less optimal steps to avoid getting trapped in local minima—and branch and bound, an approach...
To select our top picks and runners-up, we look for a mix of practical utility, novelty, and—let's be honest—a bit of coolness factor, whether that means a groundbreaking approach, an elegant solution to complex problems, or sheer cleverness in execution. This year, we’ve listened ...

Python Exercises, Practice and Solution: Write a Python function to reverse a string if its length is a multiple of 4.
Could WASM be the "write once, run everywhere" solution that developers have searched for? Where does distributing Python applications fit in the narrative? This week on the show, we have CPython core developer Brett Cannon to discuss his recent articles about WebAssembly and MVPy. Play Episode...
