如何设置变量函数的状态

# 全局变量
state = 0

def set_state(new_state):
    global state
    state = new_state

def get_state():
    return state

set_state(10)
print(get_state())  # 输出: 10

class StatefulFunction:
    def __init__(self):
        self.state = 0

    def set_state(self, new_state):
        self.state = new_state

    def get_state(self):
        return self.state

# 创建实例
sf = StatefulFunction()
sf.set_state(10)
print(sf.get_state())  # 输出: 10

def make_stateful_function(initial_state):
    state = initial_state

    def set_state(new_state):
        nonlocal state
        state = new_state

    def get_state():
        return state

    return set_state, get_state

set_state, get_state = make_stateful_function(0)
set_state(10)
print(get_state())  # 输出: 10
