如何计算函数被唯一调用的次数

# 创建一个字典来记录函数调用次数
function_calls = {}

def count_calls(func):
    def wrapper(*args, **kwargs):
        # 获取函数名
        func_name = func.__name__
        
        # 如果字典中没有该函数的计数器，则初始化为0
        if func_name not in function_calls:
            function_calls[func_name] = 0
        
        # 计数器加1
        function_calls[func_name] += 1
        
        # 调用函数
        return func(*args, **kwargs)
    
    return wrapper

@count_calls
def my_function():
    print("My function has been called.")

@count_calls
def another_function():
    print("Another function has been called.")

# 调用函数
my_function()
my_function()
another_function()

# 输出函数调用次数
print("my_function has been called", function_calls["my_function"], "times.")
print("another_function has been called", function_calls["another_function"], "times.")
