In Python, a function can return one or more values. When a function returns multiple values, it actually returns a tuple containing the values.
# -- python中的函数本质上只能返回一个值,# -- 值跟在return关键词后# -- 可以通过语法上返回多个值,值之间用逗号隔开,但是本质上返回装有多个值的元组# def get_num(): # num = input('num: ') # return num # print(get_num()) def get_two_num(): n1 = input('n1: ') n2 = input(...
n= int(input("请输入用户数字:"))ifn<0:break#此处自己实现,此函数返回列表l.append(n)#3.返回上述列表的引用关系returnl L=input_number()print("用户输入的最大数是:",max(L))print("用户输入的最小数是:",min(L))print("用户输入的全部数的和是:",sum(L)) python函数的参数传递(把数据给函数...

Python allows function to return multiple values. def prime_numbers(x): l=[] for i in range(x+1): if checkPrime(i): l.append(i) return len(l), l no_of_primes, primes_list = prime_numbers(100) Here two values are being returned. When this function is called, the return values...

defadd(x:int,y:int)->int:returnx+y 在上面的代码中,我们声明了add函数的返回类型为int。 2. 添加类型提示 在Python中,我们可以使用typing模块来为函数添加类型提示。例如,我们可以导入typing模块,并使用TypeVar来声明函数的返回类型: fromtypingimportTypeVar T=TypeVar('T')defadd(x:int,y:int)->T:return...
