Examples of Functions in Python To start, let’s define a function that takes two arguments, in this case, two numbers, and returns the sum: def sum_function(first, second): return (first + second) Let’s test our function with the numbers five and 10: print("Sum: ", sum_function(...
定义函数使用关键字def,后接函数名和放在圆括号( )中的可选参数列表,函数内容以冒号起始并且缩进。一般格式如下: def 函数名(参数列表): """文档字符串""" 函数体 return [expression] 1. 2. 3. 4. 注意:参数列表可选,文档字符串可选,return语句可选。 示例: def fib(n): """Print a Fibonacci ser...

Also please include simple test function to test the class methods. Hints: Use init method to construct some parameters Solution: class InputOutString(object): def __init__(self): self.s = "" def getString(self): self.s = input() def printString(self): print(self.s.upper()) str...

除了函数装饰器外,Python 还支持类装饰器。类装饰器通过实现 __call__ 方法来实现装饰器的功能。 classDecoratorClass:def__init__(self, func):self.func = func def__call__(self, *args, **kwargs):print("Something is happening before the function is called.")self.func(*args, **kwargs)print...

fib()是fibonacci类的一个方法，所以您必须这样调用它：
