Calling a Function To call a function, use the function name followed by parenthesis: ExampleGet your own Python Server defmy_function(): print("Hello from a function") my_function() Try it Yourself »
In this step, we will print the name of the caller function from the subfunction. This will give us the desired functionality of printing the calling function’s name. The code for this step is already included in Step 2. Explanation: Inside thesub_function(), we retrieve the previous fra...
print(f"Calling function {func.__name__} with arguments {args} and keyword arguments {kwargs}") result = func(*args, **kwargs) print(f"Function {func.__name__} finished execution") return result return wrapper 在这个例子中,simple_decorator是一个装饰器,它接受一个函数func作为参数,然后定...
def versatile_function(*args, **kwargs): print("位置参数:", args) print("关键字参数:", kwargs) versatile_function(1, 2, 3, name="李四", interests=["编程", "音乐"]) 输出结果: 位置参数: (1, 2, 3) 关键字参数: {'name': '李四', 'interests': ['编程', '音乐']} 通过上述章...
Calling function: hello Hello, world! 1. 2. 通过在函数定义前使用@print_function_name装饰器,我们可以在函数执行前自动打印函数名。 方法四:使用日志库 在实际开发中,我们通常会使用日志库来记录程序的运行情况。大多数日志库都可以自动记录函数名,我们可以使用这些日志库来打印函数名。
print(result) # Output: Hello, Norah! In the above example, we defined a function called "message" that takes one parameter 'name'. The function returns a message with the provided name. To call the "message" function, we pass the argument "Norah" inside the parentheses, and it returns...
print('hello world') # 函数结束 say_hello() # 调用函数 say_hello() # 再次调用函数 函数参数在定义函数时给定的名称称作“形参”(Parameters),在调用函数时你所提供给函数的值称作“实参”(Arguments)。 案例(保存为function_param.py): def print_max(a, b):ifa >b: ...
