Question

我正在尝试创建一个简单的用户输入tkinter GUI，用户可以在其中输入基本细节。虽然我在网上搜索过，但我无法克服这个问题：

    from tkinter import *


def user():
    print(user_entry.widget.get())
    print(email_entry.widget.get())
    print(pass1_entry.widget.get())
    print(pass2_entry.widget.get())
    pass

#main loop initial visual
main_window = Tk()
main_window.title('Register')
main_window.geometry('250x350+200+200')
main_window.configure(bg = 'Blue')

wel = Label(main_window, text="""Hello, thanks for using my software.
Please put in the details, it will be kept
safe and sent to our database""", bg = 'white')
wel.place(x = 0,y = 10)


username_lab = Label(main_window, text="Username:").place(x=0, y=64)

#us = StringVar()
user_entry = Entry(main_window)
user_entry.place(x=70,y=64)
user_entry.bind("<Return>", user())

email_lab = Label(main_window, text="Email: ").place(x=0, y=90)

#emi = StringVar()
email_entry = Entry(main_window)
email_entry.place(x=70,y=90)
email_entry.bind("<Return>", user())

pass_lab = Label(main_window, text="Password:").place(x=0, y=116)

#pas1 = StringVar()
pass1_entry = Entry(main_window, show="*")
pass1_entry.place(x=70,y=116)
pass1_entry.bind("<Return>", user())

pass_lab = Label(main_window, text="Password repeat:").place(x=0, y=140)

#pas2 = StringVar()
pass2_entry = Entry(main_window, show="*")
pass2_entry.place(x=100,y=140)
pass2_entry.bind("<Return>", user())


ok = Button(main_window, text="OK", command = user(), width=8).place(x=15, y= 175)




main_window.mainloop()

不幸的是，我一直收到这个错误，但我无法弄清楚原因。请帮助至少一件事（即用户名），其余的将遵循类似的规则。：

    Traceback (most recent call last):
  File "C:/Users/Milosz/Desktop/Programming/Register/main.py", line 28, in <module>
    user_entry.bind("<Return>", user())
  File "C:/Users/Milosz/Desktop/Programming/Register/main.py", line 5, in user
    print(user_entry.widget.get())
AttributeError: 'Entry' object has no attribute 'widget'

当您需要在输入字段上使用get()时，您只需要在变量名称上使用它。 widget()没有做你认为它在这里做的事情而且不需要。

在user():类中替换所有print语句。

自：

def user():
    print(user_entry.widget.get())
    print(email_entry.widget.get())
    print(pass1_entry.widget.get())
    print(pass2_entry.widget.get())
    pass

要：

def user():
    print(user_entry.get())
    print(email_entry.get())
    print(pass1_entry.get())
    print(pass2_entry.get())
    # removed pass as it is not needed and does nothing here.

这应该将内容打印到控制台。
