“Now that LinkedIn engineering has fully embraced Python 3, we no longer have to worry about supporting Python 2 and have seen our support loads decrease. We can now depend on the latest open source libraries and tools, and free ourselves from the constrictions of having to write bilingual Python.”

Python “ != ” 不是 “ is not ”: 对象对比在 Python
- REAL PYTHON
In this quick and practical tutorial, you’ll learn when to use the Python is, is not, == and != operators. You’ll see what these comparison operators do under the hood, dive into some quirks of object identity and interning, and define a custom class.

“As a starting point, I took a list of the most downloaded Python packages on PyPI over the past 365 days. Let’s dive in and find out what they do, how they’re related, and why they rank so high!”
(是也乎:
最具价值的模块, 多数没收录在内建中:
Urllib3;
Six(2->3 自动兼容);
botocore, boto3, s3transfer, awscli (云厂商专用模块);
Pip;Python-dateutil;Requests;
S3transfer;Certifi(SSL 支持模块我);
Idna(民族文化);
PyYAML(越来越常用的);
Pyasn1;Docutils;Chardet;
RSA;
Jmespath(叕一个 JSON 支持);
Setuptools;Pytz;Futures;
Colorama;Simplejson;
都是百万级别的下载量...

Alpine Linux 能构建更大更慢的 Python Docker
- ITAMAR TURNER-TRAURING
“When you’re choosing a base image for your Docker image, Alpine Linux is often recommended. […] But if you’re using Python, Alpine Linux will quite often: Make your builds much slower. Make your images bigger. Waste your time.” Related discussion on Hacker News.
(是也乎:
等等,这是 Alpine 的特性嘛? 只针对 Python?

Learn how to work with Python’s set data type. You’ll see how to define set objects in Python and discover the operations that they support. By the end of this course, you’ll have a good feel for when a set is an appropriate choice in your own programs.

In this tutorial, you’ll learn how to use a Flask Blueprint to help you structure your application by grouping its functionality into reusable components. You’ll learn what Blueprints are, how they work, and how you can use them to organize your code.
(是也乎:
兰图是 Flask 对应用工程的思考成果,
可惜, 整个儿 Flask 的生产力被依赖的上游模块拖乱了,
导致 Django 赢得了一切.

叕一个 gif 动画制造工具, 嗯哼, 这 logo 非常亲切了
使用也非常简单:
import gif
from matplotlib import pyplot as plt
@gif.frame
def plot(x, y):
plt.figure(figsize=(5, 3), dpi=100)
plt.scatter(x, y)
plt.xlim((0, 100))
plt.ylim((0, 100))
正常定义好一帧 plt 图片, 然后指定范围自动化生成就好, 比如:
from random import randint
frames = []
for _ in range(50):
x = [randint(0, 100) for _ in range(10)]
y = [randint(0, 100) for _ in range(10)]
frame = plot(x, y)
frames.append(frame)
