What does the “at” (@) symbol do in Python?

If we go back to the function definition syntax documentation, we see:
@f1(arg)
@f2
def func(): pass
is roughly equivalent to
def func(): pass
func = f1(arg)(f2(func))
This is a demonstration that we can call a function that's a decorator first, as well as stack decorators. Functions, i...

Linq 多字段排序，二次排序 - .NET(C#) - 清泛IT论坛，有思想、有深度
Linq：ordered = source.OrderByDescending( t => t.f1 ).ThenBy( t => t.f2 );
类似SQL：select * from t1 order by f1 desc ,f2 asc
这种写法里 OrderBy、ThenBy 是升序的，OrderByDescending、ThenByDescending 是降序的。
