Annotations are storedinthe__annotations__attribute of the function as a dictionaryandhave no effect on any other part of the function. Parameter annotations are defined by a colon after the parameter name, followed by an expression evaluating to the value of the annotation. Return annotations are...

Added type parameter to attrs.field() function for use with attrs.make_class(). Please note that type checkers ignore type metadata passed into make_class(), but it can be useful if you're wrapping attrs. #1107 It is now possible for attrs.evolve() (and attr.evolve()) to change fiel...
annotation Python是动态语⾔，变量可以随时被赋值并改变类型，也就是说Python的变量是运⾏时决定的。1def add(x, y):2 return x + y 3print(add(4, 5))4print(add('mag', 'edu'))5print(add([10], [11]))6print(add(4, 'abc')) # 不到运⾏时，⽆法判断类型是否正确 动态语⾔...
function -- 函数 可以向调用者返回某个值的一组语句。还可以向其传入零个或多个参数并在函数体执行中被使用。另见parameter,method和函数定义等节。 function annotation -- 函数标注 即针对函数形参或返回值的annotation。函数标注通常用于类型提示:例如以下函数预期接受两个int参数并预期返回一个int值:def sum_two...
