Python 3.x 如何使用框架、输入框和标签编写温度转换为C orF的Python代码？

输出应附在图像上。提前感谢您的帮助…您忘了问问题请修复代码格式。到底是什么问题？提供的代码在做什么，应该做什么？请检查我的代码。我如何才能获得像附加图像一样的精确输出？

from tkinter import*

def convert2c():
    try:
        f = float(tempIN.get())
        c = (f-32)*5.0/9.0
        tempOUTc.set(c)
    except ValueError:
        pass

def convert2f():
    try:
        c = float(tempIN.get())
        f = c*9.0/5.0 + 32
        tempOUTf.set(f)
    except ValueError:
        pass
