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.')
