Python 中 function(#) (X)格式 和 (#)在Python3.中的注意事项

def devided_3(x):
   return x/3.

class test():
  y = \'this is out of __init__()\'
  def __init__(self):
    self.y = \'this is in the __init__()\'
 
x = test  # x是类位置的首地址
print(x.y) # 输出类的内容：this is out of __init__()
x = test() # 类的实例化
print(x.y) # 输出类的属性：this is in the __init__() ;

def With_func_rtn(a):
  print(\"this is func with another func as return\")
  print(a)
  def func(b):
    print(\"this is another function\")
    print(b)
  return func
func(2018)(11)
>>> this is func with another func as return
  2018
  this is another function
  11
