Getting data from Entry

I have a part of a code some thing like this:

def topLevel():
    bugsendwindows = Toplevel(background="grey")
    bugsendwindows.title("report bug")
    buglabel1 = Label(bugsendwindows, text='title', background="white")
    buglabel1.place(x=10, y=20)
    bugtitleentry = Entry(bugsendwindows)
    bugtitleentry.place(x=50, y=20)
    bugtitleentry.focus_set()
    buglabel2 = Label(bugsendwindows, text="email", background="white")
    buglabel2.place(x=10, y=60)
    bugemailentry = Entry(bugsendwindows)
    bugemailentry.place(x=60, y=60)
    bugemailentry.focus_set()
    buglabel3 = Label(bugsendwindows, text="data", background="white")
    buglabel3.place(x=10, y=100)
    bugdataentry = Entry(bugsendwindows)
    bugdataentry.place(x=60, y=100, height=60)
    bugdataentry.focus_set()
    def Enter():
        global bugtitleentry
        global bugemail
        global bugdata
        bugtitle = bugtitleentry
        bugemail = bugemailentry
        bugdata = bugdataentry
        localtime = time.asctime(time.localtime(time.time()))
        bugwrite = open("bugreport", "w")
        bugwrite.write("title:")
        bugwrite.write(bugtitle, "\n")
        bugwrite.write("writer email:")
        bugwrite.write(bugemail, "\n")
        bugwrite.write("data:")
        bugwrite.write(bugdata, "\n")
        bugwrite.close()

    bugsend = Button(bugsendwindows, text="send",
        command=Enter)
    bugsend.place(x=10, y=150)

However, everytime I click send, It says something like this:

bugtitle = bugtitleentry
NameError: global name 'bugtitleentry' is not defined

how do i fix it so Enter can write the data to the file from topLevel?

since Enter is nested inside topLevel, it will pick up those names from the closure and no global statement is needed.

# ... <snip>
def Enter():
    bugtitle = bugtitleentry
    bugemail = bugemailentry
# </snip> ...

As a side note though, I'm not sure that the data writing will work as you expect. You probably need to use the .get() method on the Entry objects. e.g.:

bugwrite.write(bugtitle.get() + "\n")  # and file.write only takes 1 argument!
