公共字符串blaBla{获取;设置;}

本文关键字：设置 获取 字符串 blaBla | 更新日期: 2023-09-27 18:03:55

考虑下面的例子来更好地理解我的问题:

public class ClassName 
{
    public ClassName { }
    public string Val { get; set; }
    ...
}
ClassName cn = new ClassName();
cn.Val = "Hi StackOverflow!!";

这段代码在python中等价于什么?

公共字符串blaBla{获取;设置;}

您可以轻松地向任何Python对象添加成员，如其他答案所示。如要了解c#中更复杂的get/set方法，请参阅内置属性:

class Foo(object):
   def __init__(self):
      self._x = 0
   def _get_x(self):
      return self._x
   def _set_x(self, x):
      self._x = x
   def _del_x(self):
      del self._x
   x = property(_get_x, _set_x, _del_x, "the x property")

Python在这个意义上没有getter和setter。下面的代码相当于上面的代码:

class ClassName:
    pass
cn = ClassName()
cn.val = "Hi StackOverflow!!"

注意python没有提到getter/setter;你甚至不需要声明val，直到你设置它。要自定义getter/setter，你可以这样做，例如:

class ClassName:
    _val = "" # members preceded with an underscore are considered private, although this isn't enforced by the interpreter
    def set_val(self, new_val):
        self._val = new_val
    def get_val(self):
        return self._val

class a:
 pass    //you need not to declare val
x=a();
x.val="hi all";
