So what are iterators and iterables, and are they distinct? They are distinct. Iterables are classes that implement the iter method, a method which returns an iterator. Iterators are classes that implement the next method (or next in Python 2), which continuously returns the next element until the end. So this begs the question, does an iterable also have to be an iterator? Or does an iterator also have to be an iterable?

All of our project are setup with continuous deployment on CircleCI. An occasional source of errors has been caused by missing model migrations because the migration wasn’t committed. There’s a simple solution by adding a migration check before deploying.

Reddit Discussion where Python developers are sharing their favourite projects/modules. Lot of noise but found python-dependency-injector to be interesting.


挂出来的日子不长,但是 fuckit 的确值得体验...当然只是 linux/mac 党可以体验的了 )

Inspired by PEP 505 and the related discussions, this PEP proposes the addition of two new logical operators to Python:

i) Existence-checking fallback: expr1 ?else expr2

ii) Existence-checking precondition: expr1 ?and expr2.

As well as the following abbreviations for common existence checking expressions and statements

i) Existence-checking attribute access: obj?.attr (for obj ?and obj.attr ) ii) Existence-checking subscripting: obj?[expr] (for obj ?and obj[expr] ) iii) Existence-checking assignment: target ?= expr


受到动态的影响,运行时自省不足一定非常难受的, 所以,py 又接受了两种存在检验器 )

At, our goal is to make programming more accessible, and as part of this we aim to provide the full power of popular programming environments with no setup time. And no modern programming language is complete without third-party packages. That's why today we're making every Python package ever immediately available on Just select the language (Python or Python3) and start importing packages.

I came across an interesting plotting library called GooPyCharts which is a Python wrapper for the Google Charts API. In this article, we will spend a few minutes learning how to use this interesting package.

The main reason I’m in love with Python is the elegance and beauty of the design the language holds. Why not improve a bit on pip search to match the aesthetics? That’s why I created yip.

Tapioca is a Python API client maker. It gathers most of the features API clients implement and puts them in an extensible core. Wrappers will then extend this core implementing only the specifics from each service (such as authentication and pagination) and get all the common API client features for free. Tapioca approach also comes in handy because regardless of the service, clients look the same in the way you interact with them.

Originating from the standard library, inspect not only lets you look at lower level python frame and code objects, it also provides a number of methods for examining modules and classes, helping you find the items that may be of interest. It’s what pydoc uses to generate the help files mentioned previously.

I want to share 2 specific use cases that I recently encountered.

Case 1: Testing without calling a REST/SOAP API and

Case 2: Pretend that you have imported a library.
