how we can construct static effect on python instead of using class and global ?

not like that one :

global a
a = []

#simple ex ;
fonk ( a , b , d) 

   x =  1 

   a.append ( x) 

EDIT: I want to create temporary memory , if I exit the function namely fonk , I want to save change as list on temporary memory . We can do that demand only put static keyword in front of data type but in python , we dont have static, so I want that effect in python . Therefore , how can I do ?

As above code say "a" represents temporary memory
