【问题描述】：

大家好！我有一个问题，我希望你能帮助我。我正在做有问题的窗口，我想从条目中获取文本。当我得到它时（我正在使用'EntryValue = EntryName.get（）'）它没有给出错误，但是当我想用它打印它时 PyAutoGUI.typewrite(EntryValue) 它没有打印出来，因为没有任何值在我的变量中。

这是我的代码：

**from tkinter import *
import pyautogui as pg
import time
EntryThatAnswersToQuestionValue = ""
def FunctionThatCreatesWindowThatFindsProgramm():
    WindowThatFindsProgram = Toplevel(Root)
    WindowThatFindsProgram.iconbitmap(r'C:\Users\Murad\Desktop\My Factory\Programmes\J.A.R.V.I.S\Icon\QuestionIcon.ico')
    WindowThatFindsProgram.title("J.A.R.V.I.S. Has a question.")
    WindowThatFindsProgram.geometry('350x250')
    LabelThatExplainsWhatToDoInWindowThatFindsProgram = Label(WindowThatFindsProgram,text="Please, write your programm's name sir."
    ,fg='black',font='Arial 10 bold')
    LabelThatExplainsWhatToDoInWindowThatFindsProgram.pack()
    EntryThatAnswersToQuestion = Entry(WindowThatFindsProgram)
    EntryThatAnswersToQuestion.pack()
    EntryThatAnswersToQuestionValue = EntryThatAnswersToQuestion.get()
    OKButton = Button(WindowThatFindsProgram,text="     OK     ",fg='black',font='Arial 10 bold',command=FunctionThatFindsProgramm)
    OKButton.pack()
def FunctionThatFindsProgramm():
    pg.hotkey('winleft')
    time.sleep(1)
    pg.typewrite(EntryThatAnswersToQuestionValue,3)
    time.sleep(1)
    pg.hotkey('enter')**

Root = Tk()
Root.iconbitmap(r'C:\Users\Murad\Desktop\My Factory\Programmes\J.A.R.V.I.S\Icon\Icon.ico')
Root.title("J.A.R.V.I.S.")
Root.geometry('960x540')
Root['bg'] = 'black'

MainMenu = Frame(Root,bg='black')
MainMenu.pack()

JarvisTextGreeting = Label(MainMenu,text="Hello, sir. You can tell the below commands for execution.",bg='black'
,fg='blue',font='Arial 15 bold')
JarvisTextGreeting.pack()

ButtonFindingTheProgramm = Button(MainMenu,text="J.A.R.V.I.S. Please find programm that I will tell you on my PC"
,bg='blue',fg='black',font='Arial 10 bold',command=FunctionThatCreatesWindowThatFindsProgramm)
ButtonFindingTheProgramm.pack()

Root.mainloop()

【问题讨论】：

您在创建条目后立即调用了.get()。当然变量是空的——用户什么时候有机会输入任何东西？

【解决方案1】：

你必须将变量作为函数中的全局变量：

from tkinter import *
import pyautogui as pg
import time
EntryThatAnswersToQuestionValue = ""
def FunctionThatCreatesWindowThatFindsProgramm():
    global EntryThatAnswersToQuestionValue
    WindowThatFindsProgram = Toplevel(Root)
    WindowThatFindsProgram.iconbitmap(r'C:\Users\Murad\Desktop\My Factory\Programmes\J.A.R.V.I.S\Icon\QuestionIcon.ico')
    WindowThatFindsProgram.title("J.A.R.V.I.S. Has a question.")
    WindowThatFindsProgram.geometry('350x250')
    LabelThatExplainsWhatToDoInWindowThatFindsProgram = Label(WindowThatFindsProgram,text="Please, write your programm's name sir."
    ,fg='black',font='Arial 10 bold')
    LabelThatExplainsWhatToDoInWindowThatFindsProgram.pack()
    EntryThatAnswersToQuestion = Entry(WindowThatFindsProgram)
    EntryThatAnswersToQuestion.pack()
    EntryThatAnswersToQuestionValue = EntryThatAnswersToQuestion.get()
    OKButton = Button(WindowThatFindsProgram,text="     OK     ",fg='black',font='Arial 10 bold',command=FunctionThatFindsProgramm)
    OKButton.pack()
def FunctionThatFindsProgramm():
    pg.hotkey('winleft')
    time.sleep(1)
    pg.typewrite(EntryThatAnswersToQuestionValue,3)
    time.sleep(1)
    pg.hotkey('enter')

Root = Tk()
Root.iconbitmap(r'C:\Users\Murad\Desktop\My Factory\Programmes\J.A.R.V.I.S\Icon\Icon.ico')
Root.title("J.A.R.V.I.S.")
Root.geometry('960x540')
Root['bg'] = 'black'

MainMenu = Frame(Root,bg='black')
MainMenu.pack()

JarvisTextGreeting = Label(MainMenu,text="Hello, sir. You can tell the below commands for execution.",bg='black'
,fg='blue',font='Arial 15 bold')
JarvisTextGreeting.pack()

ButtonFindingTheProgramm = Button(MainMenu,text="J.A.R.V.I.S. Please find programm that I will tell you on my PC"
,bg='blue',fg='black',font='Arial 10 bold',command=FunctionThatCreatesWindowThatFindsProgramm)
ButtonFindingTheProgramm.pack()

Root.mainloop()
