• 首则 Python Notebook - 学习 Pandas
  • pandas

A step-by-step guide to analyzing data with Python and the Jupyter Notebook. This textbook will guide you through an investigation of money in politics using data from the California Civic Data Coalition. The course will teach you how to use pandas to read, filter, join, group, aggregate and rank structured data.

• 在Python中重新进行单元测试和模拟
  • testing, mocking

This post covers some higher-level software engineering principles demonstrated in my experience with Python testing over the past year and half. In particular, I want to revisit the idea of patching mock objects in unit tests.

• 数据科学: Python vs Pandas vs Numpy 的性能 - 机器学习实验
  • benchmark

Speed and time is a key factor for any Data Scientist. In business, you do not usually work with toy datasets having thousands of samples. It is more likely that your datasets will contain millions or hundreds of millions samples. Customer orders, web logs, billing events, stock prices – datasets now are huge.

虽然 Numpy 以及 Pandas 都是 python 写的, 但是,作两样的事儿, 效率就是不同的哪... )

• 通用 Jinja: 疯狂的想法 Python-ready 前端

  • jinja, frontend development

• Python 3 vs Python 2: 这次真咯不一样了

  • Python 3

A difficult decision for any Python team is whether to move from Python 2 and into Python 3. Although this is not a new decision for Python development teams, 2017 brings with it several important differences that make this decision crucial for proper forward planning. It feels like this is the year that we're really seeing the move to Python 3. It has been a long road, but Python 3 may finally have the upper hand.

• Python 中的解析: 可用的所有工具和库

  • parsing

• conda-merge

  • project, reader submission

Tool for merging Conda (Anaconda) environment files into one file. This is used to merge your application environment file with any other environment file you might need (e.g. unit-tests, debugging, jupyter notebooks) and create a consistent environment without breaking dependencies from the previous environment files.

• 创建自己的 Cryptocurrency - 用 Python
  • cryptocurrency

I’ve been itching to build my own cryptocurrency… and I shall give it an unoriginal name - Cranky Coin. After giving it a lot of thought, I decided to use Python. GIL thread concurrency is sufficient. Mining might suffer, but can be replaced with a C mining module. Most importantly, code will be easier to read for open source contributors and will be heavily unit tested. Using frozen pip dependencies, virtualenv, and vagrant or docker, we can fire this up fairly easily under any operating system.
