一个简单的图形化登陆窗口

import tkinter as tk

# 创建窗口
window = tk.Tk()
window.title('注册登陆')
window.geometry('400x400')

# 创建用户名及密码输入框
tk.Label(window, text='用户名: ').place(x=50, y=150)
tk.Label(window, text='密码: ').place(x=50, y=190)

var_usr_name = tk.StringVar()
var_usr_name.set('[email protected]')
entry_usr_name = tk.Entry(window, textvariable=var_usr_name)
entry_usr_name.place(x=160, y=150)
var_usr_pwd = tk.StringVar()
entry_usr_pwd = tk.Entry(window, textvariable=var_usr_pwd, show='*')
entry_usr_pwd.place(x=160, y=190)

# 定义用户登录功能
def usr_login():
    usr_name = var_usr_name.get()
    usr_pwd = var_usr_pwd.get()
    if usr_name == '[email protected]' and usr_pwd == '123456':
        tk.messagebox.showinfo(title='Welcome', message='欢迎您：' + usr_name)
    else:
        tk.messagebox.showerror(message='Error, your username or password is wrong, try again.')

# 定义用户注册功能
def usr_sign_up():
    pass

# 创建登录注册按钮
btn_login = tk.Button(window, text='Login', command=usr_login)
btn_login.place(x=170, y=230)
btn_sign_up = tk.Button(window, text='Sign up', command=usr_sign_up)
btn_sign_up.place(x=270, y=230)

window.mainloop()
