如何根据其他函数被调用的次数来操作开关函数？

# 定义一个全局变量来记录函数调用次数
function_calls = {}

# 计数函数调用次数的装饰器
def count_calls(func):
    def wrapper(*args, **kwargs):
        # 在函数被调用时将计数器加一
        function_calls[func.__name__] = function_calls.get(func.__name__, 0) + 1
        return func(*args, **kwargs)
    return wrapper

# 被计数的函数1
@count_calls
def function1():
    print("This is function 1.")

# 被计数的函数2
@count_calls
def function2():
    print("This is function 2.")

# 开关函数
def switch_function():
    # 根据函数调用次数执行不同的操作
    if function_calls.get("function1", 0) > 0:
        print("Function 1 has been called at least once.")
    if function_calls.get("function2", 0) > 5:
        print("Function 2 has been called more than 5 times.")

# 调用被计数的函数
function1()
function2()
function2()
function2()
function2()
function2()

# 调用开关函数
switch_function()
