python语言描写维吉尼亚演示程序的可视化界面设计代码

以下是一个基于Python tkinter的维吉尼亚演示程序的可视化界面设计代码示例：

import tkinter as tk
from tkinter import ttk

class VigenereGui:
    def __init__(self, master):
        self.master = master
        master.title("Vigenere Cipher")

        self.plain_text_label = ttk.Label(master, text="Plain Text")
        self.plain_text_label.grid(row=0, column=0, padx=5, pady=5)
        self.plain_text_entry = ttk.Entry(master, width=50)
        self.plain_text_entry.grid(row=0, column=1, padx=5, pady=5)

        self.key_label = ttk.Label(master, text="Key")
        self.key_label.grid(row=1, column=0, padx=5, pady=5)
        self.key_entry = ttk.Entry(master, width=50)
        self.key_entry.grid(row=1, column=1, padx=5, pady=5)

        self.cipher_text_label = ttk.Label(master, text="Cipher Text")
        self.cipher_text_label.grid(row=2, column=0, padx=5, pady=5)
        self.cipher_text_entry = ttk.Entry(master, width=50)
        self.cipher_text_entry.grid(row=2, column=1, padx=5, pady=5)

        self.encrypt_button = ttk.Button(master, text="Encrypt", command=self.encrypt)
        self.encrypt_button.grid(row=3, column=0, padx=5, pady=5)

        self.decrypt_button = ttk.Button(master, text="Decrypt", command=self.decrypt)
        self.decrypt_button.grid(row=3, column=1, padx=5, pady=5)

    def encrypt(self):
        plain_text = self.plain_text_entry.get()
        key = self.key_entry.get()

        # Perform Vigenere encryption
        cipher_text = ""

        for i in range(len(plain_text)):
            cipher_text += chr((ord(plain_text[i]) + ord(key[i % len(key)])) % 26 + ord('A'))

        self.cipher_text_entry.delete(0, tk.END)
        self.cipher_text_entry.insert(0, cipher_text)

    def decrypt(self):
        cipher_text = self.cipher_text_entry.get()
        key = self.key_entry.get()

        # Perform Vigenere decryption
        plain_text = ""

        for i in range(len(cipher_text)):
            plain_text += chr((ord(cipher_text[i]) - ord(key[i % len(key)])) % 26 + ord('A'))

        self.plain_text_entry.delete(0, tk.END)
        self.plain_text_entry.insert(0, plain_text)

root = tk.Tk()
vigenere_gui = VigenereGui(root)
root.mainloop()

该代码使用tkinter库创建了一个具有三个文本框和两个按钮的窗口。用户可以在第一个文本框中输入明文，在第二个文本框中输入密钥，并通过单击“Encrypt”按钮进行加密。加密后的密文将显示在第三个文本框中。同样，用户也可以在第三个文本框中输入密文，并通过单击“Decrypt”按钮进行解密。解密后的明文将显示在第一个文本框中。
