如何在pycharm python上从3到6按钮进行乘法和求和

我正在学习使用python和tkinter制作应用程序。 我做了一个电阻计算器。问题是如何计算几个按钮的乘法和加法以获得值，并将总结果写入电阻器值输入框

更糟糕的是，我不知道如何在这里编写代码。所以我给了链接

多谢各位

---

在函数

SetBand

after

varX.set（）

中，您可以执行计算值并在条目中更新值的函数

---

其他更改（减少了代码行）：

我在列表中保留颜色和按钮文本，以便使用

for

-loop（使用

zip（）

和

enumerate（）

）生成按钮。我将按钮保留在列表中，以便以后可以使用

for

-loop来更改按钮中的状态

在

command=

中，我使用

lamba

，这样我就可以用不同的参数分配相同的函数

完整的工作代码，但我不确定是否所有的工作预期

顺便说一句：如果我将

IntVar

保留在列表中，那么我可以使用一个

set\u波段（self，number，value）

而不是

set\u波段1（self，value）

，

set\u波段2（self，value）

，等等。

如果你想让人们帮助你，请学习如何在这里发布，因为人们不会倾向于点击随机链接。将代码放入问题中，并使用按钮

{}

设置格式。发布相关代码，突出显示它，当你开始一次又一次地给变量名添加数字时，按下

Ctrl+K

，就会出现问题，你应该使用适当的数据结构（列表、字典等）。你应该在列表上保留所有

IntVar（）

和按钮，然后你可以使用

for

-循环来缩短代码。谢谢你的回答。但是如何将值ex:1000格式化为1k等。如果rad.button 3处于活动状态，如何将值v1从*1000更改为*10要将

1000

格式化为

1k

必须手动执行-除以1000，结果转换为字符串并添加字符

k

。如果只想转换大于1000的值，请使用

If/else

-ie.

If-value>=1000:。当您想要转换到

1M

时类似。首先检查

if value>=1000000`，然后除以

1 000 000

，将结果转换为字符串并添加字符

M

，如果您想在按钮3处于活动状态时使用*1000而不是*10，那么当您在

更新标签

no.1中计算值时，请使用

if/elif/else

。我还是不知道如何转换，第二，乘法不变
