Posted 2021-01-05 李莹琳

while True:
    a = int(input(\'摄氏度转换为华氏温度请按1\\n华氏温度转化为摄氏温度请按2\\n\'))

    if a == 1:
        celsius = float(input(\'输入摄氏温度：\'))
        fahreaheit = (celsius + 1.8) + 32  # f = c+9/5+32
        print(\'{:.2f}摄氏温度转为华氏温度为{:.2f}\'.format(celsius, fahreaheit))
    elif a == 2:
        celsius1 = float(input(\'输入华氏温度：\'))
        fahreaheit1 = (celsius1 - 32) * 5 / 9
        print(\'{:.2f}华氏温度转化为摄氏温度为{:.2f}\'.format(celsius1, fahreaheit1))
    else:
        break;

第二题

import random
secret = random.randint(1,20)
#print(secret)
print(\'-------猜我新买的玩具多少钱！--------\')
guess = -1
while guess != secret:
    a = input(\'请输入数字:\')
    guess = int(a)
    if guess > secret:
        print(\'输入的数字太大！\')
    elif guess < secret :
        print(\'输入的数字太小！\')
    else :
        print(\'猜对了！\')
        print(\'game over,bye!O(∩_∩)O\')
