[英]Tkinter GUI window not recognised in other functions
I am making a simple program that saves someone's name and their email address in a file.我正在制作一个简单的程序,将某人的姓名和他们的电子邮件地址保存在一个文件中。 I am coding in python idle.
我在 python idle 中编码。 My code is:
我的代码是:
import random
from tkinter import *
num = (random.randint(1,3))
NOSa = open("CN.txt", "r")
NOS = (NOSa.read())
NOSa.close()
NOSa = open("CN.txt", "w")
if num == ("1"):
NOS = NOS + "a"
elif num == ("2"):
NOS = NOS + "v"
else:
NOS = NOS + "x"
NOSa.write(NOS)
NOSa.close()
def efg():
window2.destroy()
window2.mainloop()
exit()
def abc():
name = entry.get()
email = entry2.get()
window.destroy()
window2 = Tk()
window2.title("OP")
OT = Text(window2, width=30, height=10, wrap=WORD, background="yellow")
OT.grid(row=0, column=0, sticky=W)
OT.delete(0.0, END)
MT = "We have logged your details " + name
MT2 = ". We have a file saved called " + NOS
MT3 = ". Go check it out!"
OT.insert(END, MT)
OT.insert(END, MT2)
OT.insert(END, MT3)
new_file = open(NOS, "a")
new_file.write("This is ")
new_file.write(name)
new_file.write(" email address.")
new_file.write(" ")
new_file.write(email)
button2 = Button(window2, text="OK", width=5, command=efg)
button2.grid(row=1, column=0, sticky=W)
window.mainloop()
window2.mainloop()
window = Tk()
window.title("EN")
label = Label(window, text="Enter your name: ")
label.grid(row=0, column=0, sticky=W)
entry = Entry(window, width=20, bg="light green")
entry.grid(row=1, column=0, sticky=W)
label2 = Label(window, text="Enter your email address: ")
label2.grid(row=2, column=0, sticky=W)
entry2 = Entry(window, width=25, bg="light green")
entry2.grid(row=3, column=0, sticky=W)
button = Button(window, text="SUBMIT", width=5, command=abc)
button.grid(row=4, column=0, sticky=W)
window.mainloop()
When I run the code my first 2 boxes appear and run their code perfectly.当我运行代码时,我的前两个框出现并完美地运行它们的代码。 However, when I click the button 'OK' I get this error: NameError: name 'window2' is not defined
但是,当我单击“确定”按钮时,出现此错误:NameError: name 'window2' is not defined
I use python-idle.我使用 python 空闲。
You may make windows2
global您可以将
windows2
全局
window2 = None
def efg():
global window2
and later然后
def abc():
global window2
