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 »
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...

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(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: ...
print(slow_function(2)) 在这个例子中,timing_decorator装饰器记录了slow_function的执行时间,并在执行后打印出来。装饰器通过接收slow_function函数,并返回一个新的函数wrapper,实现了功能的扩展。 带参数的装饰器 有时候我们需要让装饰器接受额外的参数,以便根据不同的需求灵活调整装饰器的行为。为此,我们可以创建一...
