用python写一个带有gui界面的密码生成器

from tkinter import *
import random, string
import pyperclip


root =Tk()
root.geometry(\"400x400\")
root.resizable(0,0)
root.title(\"密码生成器\")


heading = Label(root, text = \'密码\' , font =\'arial 15 bold\').pack()


pass_label = Label(root, text = \'密码长度\', font = \'arial 10 bold\').pack()
pass_len = IntVar()
length = Spinbox(root, from_ = 8, to_ = 32 , textvariable = pass_len , width = 15).pack()



pass_str = StringVar()

def Generator():
  password = \'\'
  for x in range (0,4):
    password = random.choice(string.ascii_uppercase)+random.choice(string.ascii_lowercase)+random.choice(string.digits)+random.choice(string.punctuation)
  for y in range(pass_len.get()- 4):
    password = password+random.choice(string.ascii_uppercase + string.ascii_lowercase + string.digits + string.punctuation)
  pass_str.set(password)
  

Button(root, text = \"获取密码\" , command = Generator ).pack(pady= 5)

Entry(root , textvariable = pass_str).pack()


def Copy_password():
  pyperclip.copy(pass_str.get())

Button(root, text = \'复制密码\', command = Copy_password).pack(pady=5)


root.mainloop()
