最上面都是注释，不用看，是我上一个作业里的东西

非常抱歉，我误解了问题。根据你提供的错误信息和代码，发现问题出在你的代码中的拼写错误上。在 `LoginPage` 类中，你定义了一个名为 `buttonLogin` 的方法。但是，在创建按钮时，你却将该方法命名为 `bottonLogin`（缺少一个"t"）。所以，只需将按钮的 `command` 参数中的方法名由 `bottonLogin` 改为 `buttonLogin` 即可。

修改后的代码如下：

from tkinter import *

FONT = ('Microsoft YaHei', 12)

class LoginPage():
def __init__(self, master):
   self.master = master
   self.initUI()

def initUI(self):
   self.centerWindow()
   self.logo = PhotoImage(file="logo.png")
   self.iconLogin = PhotoImage(file="iconLogin.png")
   self.iconCancel = PhotoImage(file="iconCancel.png")
   Label(self.master, justify=LEFT, image=self.logo).grid(row=0, column=0, rowspan=2)
   Label(self.master, text='账号', font=FONT).grid(row=0, column=1)
   Label(self.master, text='密码', font=FONT).grid(row=1, column=1)
   self.entryUser = Entry(self.master, width=15)
   self.entryUser.grid(row=0, column=2)
   self.entryPsw = Entry(self.master, width=15, show='*')
   self.entryPsw.grid(row=1, column=2)
   Button(self.master, compound=LEFT, image=self.iconLogin, text='登录', font=FONT,
            command=self.buttonLogin).grid(row=2, column=1)
   Button(self.master, compound=LEFT, image=self.iconCancel, text='取消', font=FONT,
            command=self.master.quit).grid(row=2, column=2)

def buttonLogin(self):
   user = self.entryUser.get()
   psw = self.entryPsw.get()
   if user and psw:
         print("UserName:%s\nPassword:%s" % (user, psw))
   else:
         print("Please Enter UserName and Password!")

def centerWindow(self):
   screen_width = self.master.winfo_screenwidth()
   screen_height = self.master.winfo_screenheight()
   x = (screen_width - 200) / 2
   y = (screen_height - 100) / 2
   self.master.geometry('260x100+%d+%d' % (x, y))
   self.master.title("LoginGUI")

def main():
window = Tk()
LoginPage(window)
window.mainloop()

if __name__ == '__main__':
main()

你好！从错误信息来看，问题出在 `LoginPage` 类中的 `bottonLogin` 方法上，因为拼写错误导致无法找到该方法。请将 `self.bottonLogin` 改为 `self.buttonLogin`，即将 `button` 第一个字母的大小写调整正确。修改后的代码如下：

from tkinter import *

FONT = ('Microsoft YaHei', 12)

class LoginPage():
def __init__(self, master):
   self.master = master
   self.initUI()

def initUI(self):
   self.centerWindow()
   self.logo = PhotoImage(file="logo.png")
   self.iconLogin = PhotoImage(file="iconLogin.png")
   self.iconCancel = PhotoImage(file="iconCancel.png")
   Label(self.master, justify=LEFT, image=self.logo).grid(row=0, column=0, rowspan=2)
   Label(self.master, text='账号', font=FONT).grid(row=0, column=1)
   Label(self.master, text='密码', font=FONT).grid(row=1, column=1)
   self.entryUser = Entry(self.master, width=15)
   self.entryUser.grid(row=0, column=2)
   self.entryPsw = Entry(self.master, width=15, show='*')
   self.entryPsw.grid(row=1, column=2)
   Button(self.master, compound=LEFT, image=self.iconLogin, text='登录', font=FONT,
            command=self.buttonLogin).grid(row=2, column=1)
   Button(self.master, compound=LEFT, image=self.iconCancel, text='取消', font=FONT,
            command=self.master.quit).grid(row=2, column=2)

def buttonLogin(self):
   user = self.entryUser.get()
   psw = self.entryPsw.get()
   if user and psw:
         print("UserName:%s\nPassword:%s" % (user, psw))
   else:
         print("Please Enter UserName and Password!")

def centerWindow(self):
   screen_width = self.master.winfo_screenwidth()
   screen_height = self.master.winfo_screenheight()
   x = (screen_width - 200) / 2
   y = (screen_height - 100) / 2
   self.master.geometry('260x100+%d+%d' % (x, y))
   self.master.title("LoginGUI")

def main():
window = Tk()
LoginPage(window)
window.mainloop()

if __name__ == '__main__':
main()
