[英]Tkinter - How to get integer Entry values?
I tried doing it based on other people's code with the same problem but I couldn't do it. 我尝试根据具有相同问题的其他人的代码来执行此操作,但是我做不到。
The problem here is that the code doesn't get the value from the Entry
boxes before doing the calculate
function. 这里的问题是代码在执行
calculate
功能之前没有从“ Entry
框中获取值。
I posted this version because this one executes the code, while other methods I tried gave error messages. 我发布了此版本,因为该版本执行了代码,而我尝试的其他方法给出了错误消息。

You are overwriting your Entry
widgets. 您正在覆盖
Entry
小部件。
remove the following code: 删除以下代码:
U = IntVar()
AH = IntVar()
BH = IntVar()
CH = IntVar()
AHmBH = IntVar()
AHmCH = IntVar()
CHmBH = IntVar()
AHmBHmCH = IntVar()
And place your E
variable within your Calculate
function 并将
E
变量放入Calculate
函数中
The final code should look like this: 最终代码应如下所示:

I should add, that you indentation is all over the place. 我要补充一点,就是缩进到处都是。 Please, try and either keep it to tabs only, or 4 spaces.
请尝试将其仅保留在制表符或4个空格中。 Do not mix and match, and please - do not use indents of 1/2/3 spaces.
请勿混用,请-请勿使用1/2/3空格的缩进。
And in the future, try to use meaningful variable names. 将来,请尝试使用有意义的变量名。
E
, U
, and etc, are not very meaningful and are really ambiguous. E
, U
等不是很有意义,并且实际上是模棱两可的。 Try to avoid this. 尽量避免这种情况。
