练手例子_main函数、调用其他函数、输入字符保存

# hello3.py
import hello4

person = {'Alice': 13, 'Bob': 35, 'May': 56, 'Lin': 29}
body_name = ['head', 'body', 'hand', 'leg', 'foot']


# 找出想要的字符串
def number_name():
    n = int(input('Input a number:\n'))
    if 0 < n < 5:
        print(body_name[n])
    else:
        print("Please input a number in 0 and 4")
        hello4.get_time()


# 找出年纪最大的人
def age_old():
    p_name = 'Alice'
    for key in person.keys():
        if person[p_name] < person[key]:
            p_name = key
    print('%s,%d', (p_name, person[p_name]))


# 保存所有输入的字符串到test.txt文件中
def save_text():
    fp = open('text.txt', 'w')
    string = input('Please input a string:\n')
    fp.write(string)
    fp.closed


# __name__ == “__main__” 作为启动py文件的main函数入口
if __name__ == "__main__":
    save_text()
