And there’s no single correct format. You need to know how to melt, pivot, and transpose data into a format that fits whatever you’re analyzing. If you enjoy this article, be sure to also check out Stefanie’s Pandas Workshop. (是也乎: 真.从来没在 Excel 中用过 数据透视表, 应该还是翻译的问题… ) FastAPI 和 Pydantic 的未来一片光明 SEBASTIÁN RAMÍREZ • Shared by Alex Mitelman Not long ago there was some chatter on the internet about a change in Python 3.10 that would impact Python projects that check types at runtime. The discussion centered around FastAPI and Pydantic and had some folks worried about the future of those projects. In this article, FastAPI’s creator explains what the discussion was all about and why the future of FastAPI and Pydantic remains bright. 用 Python 简化复数 REAL PYTHON In this tutorial, you’ll learn about the unique treatment of complex numbers in Python.

Excel/Python 和数据科学的未来 MATT ASAY What’s the most widely used tool in data science? Is it pandas or NumPy? Is it the Python language itself? Not really. It’s Excel. You might argue that data scientists aren’t using Excel as their primary tool, and you might be right. But Excel enables non-technical users, like small business owners, to gain insights into their data. In this article, Anaconda CEO Peter Wang discusses his goal of making Python and PyData the “conceptual successor” to Excel. (是也乎: 对的, 无论 Jupyter 怎么折腾, 如果 Excel 嵌入 Python, 那么瞬间, 没 notebook 什么事儿了… ) 数据分析用实 SQL HAKI BENITA If you need to do some data analysis, what tool do you reach for first? Is it pandas? While pandas is great, it comes with some costs that you might not be aware of, including large memory overhead that can quickly get in the way of your projects. Using databases with SQL can alleviate memory issues. In this tutorial, you’ll learn how to do common data analysis tasks in SQL, which opens the door to mixing SQL and pandas to create lightweight programs that are also fast!
