• Python 函式不是你所想咯
  • core-python, functions

Python functions cannot have names. In this world view, every function is a nameless, anonymous object. Code like "def to_percent(numbers)" creates a nameless function object, then stores it in a variable called "to_percent".

(是也乎:

不同的世界观中, Py 的函式机制都可以自洽

• Api Star
  • video

This is a presentation I gave at a local python user group in Nashville, PyNash. The topic of the night was to pick a lesser-known or up and coming library that many folks may not be aware of yet and give a 10 minute overview.

• 用 Python 和 Pandas 对价格进行分析和评级
  • pandas

I recently began investing and was wondering how good analysts are at predicting the future of a company.

• 用 Machine Learning 进行文本分类
  • machine learning

In this post, we will be trying to make a text classifier that will make use of the 20 news groups dataset originally developed by Ken Lang to classify documents into different categories based on their content.

• 在 Python 中用起 YAML
  • YAML

YAML stands for "YAML Ain't Markup Language" and is mostly used in configuration files. YAML, in contrary to JSON, is made to be very readable and is not designed to be used for api's or other communication protocols. This is because the parsing of a YAML file requires the computer a little bit more effort than parsing a JSON file.

(是也乎:

Yaml 虽然比 JSON 可读,但是无论创建和解析都比较嗯哼... )

• 转换 cURL 指令为 Python requests

• 在 Python 用 Excel-样 列名来索引
  • codesnippet

(是也乎:

就两行代码:

def to_idx(letters):
    val = lambda i, x: (26**i) * (ord(x.lower()) - ord('a') + 1)
    return sum([val(i, x) for i, x in enumerate(letters[::-1])]) - 1

效果:

>>> to_idx('A')
0
>>> to_idx('AH')
33
>>> to_idx('XFD')
16383

• 用 Bokeh, Flask 和 Python 3 构建响应式 Bar Charts
  • chart

Bokeh is a powerful open source Python library that allows developers to generate JavaScript data visualizations for their web applications without writing any JavaScript. While learning a JavaScript-based data visualization library like d3.js can be useful, it's often far easier to knock out a few lines of Python code to get the job done.

(是也乎:

Bokeh 是个专用库, 能将 py 数据对象转换为 JS 的. )
