while True:
    a = int(input(\'摄氏度转华氏度请按 1\\n 华氏度转摄氏度请按 2\\n退出请按 3\\n\'))

    if a == 1:
         c = float(input (\'请输入一个摄氏温度\'))
         f = c*9/5+32
         print(\'摄氏｛:.2f｝的华氏为{:.2f}\\n\'.format(c,f))
    elif a == 2:
         f  = float(input(\'请输入华氏温度：\'))
         c = 5/9*(f-32)
         print(\'华氏{:.2f}的摄氏度为{:.2f}\\n\'.format(f,c))
    else:
        break
