Python doesn’t have true constants, nor does it implement features like tail recursion optimization that many compiled languages employ. Find out what other features Python is “missing” when compared to other languages, and why the core developers haven’t added these features to the language.

(是也乎:

哪四大?

真常量; 真重载和泛型; 尾递归优化; 多行λ.

简单说, 就是 真LISP 化. )

In this tutorial, you’ll learn how to customize Django’s admin with Python. You’ll use AdminModel objects to add display columns, calculate values, link to referring objects, and search and filter results. You’ll also use template overriding to gain full control over the admin’s HTML.
