請你幫我用python製作一個二維碼生成器，需要有GUI窗口

好的，我可以使用Python中的qrcode和tkinter模块来实现这个二维码生成器。以下是代码实现：

import qrcode
import tkinter as tk
from tkinter import messagebox, filedialog

class QrCodeGenerator:
    def __init__(self, master):
        self.master = master
        master.title('QR Code Generator')

        # Create input label and entry
        self.input_label = tk.Label(master, text='Enter text or link:')
        self.input_label.pack()
        self.input_entry = tk.Entry(master, width=50)
        self.input_entry.pack()

        # Create button to generate QR code
        self.generate_button = tk.Button(master, text='Generate QR Code', command=self.generate_qr_code)
        self.generate_button.pack()

        # Create button to save QR code
        self.save_button = tk.Button(master, text='Save QR Code', command=self.save_qr_code, state=tk.DISABLED)
        self.save_button.pack()

    def generate_qr_code(self):
        # Get input from user
        input_text = self.input_entry.get()

        # Check if input is empty
        if not input_text:
            messagebox.showerror('Error', 'Please enter text or link')
            return

        # Generate QR code
        qr = qrcode.QRCode(version=1, box_size=10, border=5)
        qr.add_data(input_text)
        qr.make(fit=True)
        qr_image = qr.make_image(fill_color='black', back_color='white')

        # Display QR code
        self.qr_code_display = tk.Label(self.master, image=qr_image)
        self.qr_code_display.pack()

        # Enable save button
        self.save_button.config(state=tk.NORMAL)

    def save_qr_code(self):
        # Get file path from user
        file_path = filedialog.asksaveasfilename(defaultextension='.png')

        # Check if file path is empty
        if not file_path:
            return

        # Get QR code image and save to file
        qr_code_image = self.qr_code_display['image']
        qr_code_image.save(file_path)

        # Show success message
        messagebox.showinfo('Success', 'QR code saved successfully')

# Create GUI window
root = tk.Tk()
qr_code_generator = QrCodeGenerator(root)
root.mainloop()

当你运行这个代码时，会弹出一个窗口，让你输入要转换为二维码的文本或链接。单击“生成QR代码”按钮后，它将在窗口中显示QR代码。如果您想保存QR代码，单击“保存QR代码”按钮并选择要保存的文件路径。
