半小时的时间讲清买房赚钱的逻辑2(小白篇)

最近和20多岁的人接触比较多,结合自己过往的经验,关于房子这件事,很想多说那么一两句。
因为超出一些人的年龄范畴和经验范畴,之前说的真蛮难被听进去的,好在最近有一个朋友听进去了,启发到我给出更容易接受的内容。

我知道房子这件事,很多人已经躺平,或者直觉觉

标题说是一个好房子的素养,或者说是,维护好房子的素养,或者,挑选好房子的素养,或者是健康

Issue 477

Excel+Py 就是数据科学的未来?

原文: PyCoder's Weekly - Issue #477

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...

)

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!

(是也乎:

SQL 永远的语言

)

In this tutorial, you’ll prepare for future interviews by working through a set of Python practice problems that involve CSV files. You’ll work through the problems yourself and then compare your results with solutions developed by the Real Python team.

(是也乎:

常年手工解析 .csv 的俺...

)

(是也乎:

嗯哼? 这个热点蹭得专业哪...

)

打死也不发布 1.0 党

探讨/吐糟

Discussions

Chaining together many object methods can create long tines that break the PEP 8 79-character line length recommendation. You can use \ to break the chain of methods onto individual lines, but if you want to leave comments at the end of some of the lines, you’re out of luck. There’s another pattern, though, that solves this.

Brian Okken, co-host of the Python Bytes podcast, asks Twitter users about internal package distribution, and the Twitterverse responds.

(是也乎:

S3->GCP->Devpi

还是用 Devpi 发布内源 PyPI 最简洁了.

)


文章/教程/嗯哼

Articles, Tutorials and Talks

Follow along with this in-depth analysis of LEGO prices to see Bayesian analysis in action. Along the way, you’ll how pooled and unpooled linear models can be used to determine if a LEGO set is fairly priced. The article is quite technical, so experience with Bayesian statistics is recommended.

(是也乎:

PyMC 原先只是作为课堂讲义, 没想到慢慢的, 变成了 Bayes 标准库了...

)

Community-based programming courses are a great way to introduce folks to computer programming that otherwise may not have the means to do so. One of the barriers to learning to code is cost. You need a computer to program on, after all. But with the advent of tiny computers like the Raspberry Pi, computers aimed at education are more affordable than ever.

(是也乎:

RPi 400

用 RPi 替代主机配合显示屏+mouse+键盘, 形成只能学习编程的环境, 这下学员没办法安装游戏来玩了?

)

With this Python project, you’ll build a script to calculate grades for a class using pandas. The script will quickly and accurately calculate grades from a variety of data sources. You’ll see examples of loading, merging, and saving data with pandas, as well as plotting some summary statistics.

Are you looking for an in-depth data science project to practice your skills on? Perhaps you would like to add new tools to your Python web development projects instead? This week on the show, David Amos is back, and he’s brought another batch of PyCoder’s Weekly articles and projects.

(是也乎:

Vue 真自成一派了.

PEP 661 proposes adding a utility for defining sentinel values in the standard library. In this article, you’ll get a summary of PEP 661, learn what sentinel objects are with real-world examples, and see how to use them with type hints.

In this step-by-step tutorial, you’ll learn how Python’s filter() works and how to use it effectively in your programs. You’ll also learn how to use list comprehension and generator expressions to replace filter() and make your code more Pythonic.

(是也乎:

filter

还是得配合 lambda 才能有麽幻感觉

)
