题目描述
【Say Hi】：你的任务是编写一个根据给出的属性参数来介绍一个人的函数
【链接】：https://py.checkio.org/mission/say-history/
【输入】：两个参数，一个字符串（str）和一个正整数（int）
【输出】：字符串（str）
【范例】：
say_hi("Alex", 32) == "Hi. My name is Alex and I'm 32 years old"say_hi("Frank", 68) == "Hi. My name is Frank and I'm 68 years old" 代码实现 # 1. on CheckiO your solution should be a function# 2. the function should return the right answer, not print it.def say_hi(name: str, age: int) -> str:return "Hi. My name is " + name + " and I'm " + str(age) + " years old"if __name__ == '__main__':#These "asserts" using only for self-checking and not necessary for auto-testingassert say_hi("Alex", 32) == "Hi. My name is Alex and I'm 32 years old", "First"assert say_hi("Frank", 68) == "Hi. My name is Frank and I'm 68 years old", "Second"print('Done. Time to Check.') 大神解答 大神解答 NO.1 def say_hi(name: str, age: int) -> str:return f"Hi. My name is {name} and I'm {age} years old" 大神解答 NO.2 def say_hi(name: str, age: int) -> str:return "Hi. My name is {0} and I'm {1} years old".format(name, age)
