[Python] 정적변수 사용하기

It seems that classes can have static variables in Python. The following is for using static variables within function.

참고:  http://stackoverflow.com/questions/279561/what-is-the-python-equivalent-of-static-variables-inside-a-function (What is the idiomatic Python equivalent of this C/C++ code? )


--------------------------------
def foo():

  foo.counter.append('a')

  print foo.counter

foo.counter=[] # 함수 외부에서 초기화.

foo() # 거듭해서 호출해볼 것.
