首先确保你安装了必要的库：

pip install qrcode Pillow

代码如下：

import tkinter as tk
from tkinter import filedialog, messagebox
import qrcode
from barcode import EAN13
from barcode.writer import ImageWriter
from PIL import ImageTk, Image
class BarcodeGeneratorApp:
   def __init__(self, master):
       self.master = master
       master.title("二维码 & 条形码生成器")
       # 初始化图像变量
       self.qr_image = None
       self.bar_image = None
       # 二维码部分
       qr_frame = tk.Frame(master, padx=20, pady=20)
       qr_frame.pack(side=tk.LEFT)
       self.qr_label = tk.Label(qr_frame)
       self.qr_label.pack()
       self.qr_entry = tk.Entry(qr_frame)
       self.qr_entry.pack(pady=(0, 10))
       qr_gen_button = tk.Button(qr_frame, text="生成二维码", command=self.generate_qr_code)
       qr_gen_button.pack()
       qr_save_button = tk.Button(qr_frame, text="保存二维码", command=self.save_qr)
       qr_save_button.pack()
       # 条形码部分
       bar_frame = tk.Frame(master, padx=20, pady=20)
       bar_frame.pack(side=tk.RIGHT)
       self.bar_label = tk.Label(bar_frame)
       self.bar_label.pack()
       self.bar_entry = tk.Entry(bar_frame)
       self.bar_entry.pack(pady=(0, 10))
       bar_gen_button = tk.Button(bar_frame, text="生成条形码", command=self.generate_bar_code)
       bar_gen_button.pack()
       bar_save_button = tk.Button(bar_frame, text="保存条形码", command=self.save_bar)
       bar_save_button.pack()
   def generate_qr_code(self):
       data = self.qr_entry.get()
       if data:
           img = qrcode.make(data)
           img.save("qr_code.png")
           self.qr_image = Image.open("qr_code.png")
           self.qr_image.thumbnail((200, 200))
           qr_photo = ImageTk.PhotoImage(self.qr_image)
           self.qr_label.config(image=qr_photo)
           self.qr_label.image = qr_photo
       else:
           messagebox.showwarning("警告", "请输入内容以生成二维码！")
   def generate_bar_code(self):
       data = self.bar_entry.get()
       if data.isdigit() and (len(data) == 12 or len(data) == 13):
           ean = EAN13(data, writer=ImageWriter())
           filename = ean.save("bar_code.png")  # 确保保存为png文件
           self.bar_image = Image.open(filename)
           self.bar_image.thumbnail((200, 100))
           bar_photo = ImageTk.PhotoImage(self.bar_image)
           self.bar_label.config(image=bar_photo)
           self.bar_label.image = bar_photo
       else:
           messagebox.showwarning("警告", "请输入有效的12或13位数字以生成条形码！")
   def save_qr(self):
       if self.qr_image:
           file_path = filedialog.asksaveasfilename(defaultextension=".png")
           if file_path:
               self.qr_image.save(file_path)
               messagebox.showinfo("成功", "二维码已保存！")
   def save_bar(self):
       if self.bar_image:
           file_path = filedialog.asksaveasfilename(defaultextension=".png")
           if file_path:
               self.bar_image.save(file_path)
               messagebox.showinfo("成功", "条形码已保存！")
if __name__ == "__main__":
   root = tk.Tk()
   app = BarcodeGeneratorApp(root)
   root.mainloop()

这段代码创建了一个简单的GUI应用程序，用户可以在输入框中输入想要生成二维码、条形码的数据，点击“生成二维码、条形码”按钮后，程序会弹出保存对话框让用户选择保存位置，随后将生成的二维码、条形码图片保存到指定位置。
