How to get an integer from a tkinter entry box?
提问by
I am trying to work out how to get a value from a tkinter entry box, and then store it as a integer. This is what I have:
我正在尝试解决如何从 tkinter 输入框中获取值，然后将其存储为整数。这就是我所拥有的：
AnswerVar = IntVar()
AnswerBox = Entry(topFrame)
AdditionQuestionLeftSide = random.randint(0, 10)
AdditionQuestionRightSide = random.randint(0, 10)
AdditionQuestionRightSide = Label(topFrame, text= AdditionQuestionRightSide).grid(row=0,column=0)
AdditionSign = Label(topFrame, text="+").grid(row=0,column=1)
AdditionQuestionLeftSide= Label(topFrame, text= AdditionQuestionLeftSide).grid(row=0,column=2)
EqualsSign = Label(topFrame, text="=").grid(row=0,column=3)
AnswerBox.grid(row=0,column=4)
answerVar = AnswerBox.get()
root.mainloop()

)
I want to take then input from AnswerBox, and store it in the integer variable "answer". How can I do this?
我想从 AnswerBox 获取然后输入，并将其存储在整数变量“answer”中。我怎样才能做到这一点？
Thanks

Since you have an IntVarassociated with the entry widget, all you need to do is get the value of that object with the getmethod:
由于您有一个IntVar与条目小部件相关联，您需要做的就是使用以下get方法获取该对象的值：
int_answer = answer.get()
If you don't use an IntVar, you can get the value of the entry widget and the convert it to an integer with int:
如果不使用IntVar，则可以获取条目小部件的值并将其转换为整数int：
string_answer = AnswerBox.get()
int_answer = int(string_answer)

To get a value from an Entry widget in tkinter you call the get()method on the widget. This will return the widget's value.
要从 tkinter 中的 Entry 小部件获取值，您可以调用get()小部件上的方法。这将返回小部件的值。
So you would do answer = AnswerBox.get()
所以你会做 answer = AnswerBox.get()
