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...
标注function-annotation以字典的形式存放在函数的__annotations__属性中,并且不会影响函数的任何其他部分。 形参标注的定义方式是在形参名后加冒号,后面跟一个表达式,该表达式会被求值为标注的值。 返回值标注的定义方式是加组合符号->,后面跟一个表达式,该标注位于形参列表和表示def语句结束的冒号之间。 下面的示例有...

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...
