python-函数式编程&面向对象编程

• python是面向对象语言,一切皆对象,既支持面向对象编程,也支持函数式编程

第一个功能:print传入的值

①

def func(a):
  print(a)

def main():
  func('zhangsan')

②

class Demo:
  def __init__(self):
    self.a = None

   def func(self):
      print(self.a)

def main():
  d = Demo()
  d.a = 'zhangsan'
  d.func()

③

class Demo:
  def __init__(self):
    self._a = None

  @property
  def a(self):
    return self._a

  @a.setter
  def a(self, value):
    self._a = value

  def func(slef):
    print(self.a)

def main():
  d = Demo()
  d.a = 'zhangsan'
  d.func()
