python可视化登录界面

以下是一个基本的Python可视化登录界面的代码示例：

from tkinter import *
from tkinter import messagebox

def login():
    username = entry_username.get()
    password = entry_password.get()
    if username == "admin" and password == "password":
        messagebox.showinfo("Login", "Login successful!")
    else:
        messagebox.showerror("Login", "Incorrect username or password!")

# Create the main window
root = Tk()
root.title("Login")

# Create the username label and entry
label_username = Label(root, text="Username:")
label_username.pack()
entry_username = Entry(root)
entry_username.pack()

# Create the password label and entry
label_password = Label(root, text="Password:")
label_password.pack()
entry_password = Entry(root, show="*")
entry_password.pack()

# Create the login button
button_login = Button(root, text="Login", command=login)
button_login.pack()

# Run the main loop
root.mainloop()

请注意，此代码仅用于示例目的。在实际应用中，您应该使用更安全的身份验证方法，例如使用密码哈希和加盐。
