你可以使用字符串的切片功能将加密后的手机号分成三段，然后分别显示在三个 Label 中。下面是一个修改过的代码示例：

def fpe(frame_phone_input, root):
    phone_input = frame_phone_input.get()
    
    def fpe_encrypt(plaintext, key, radix=10, rounds=4):
        # 对明文进行哈希
        hash_val = hmac.new(key.encode(), plaintext.encode(), hashlib.sha256).digest()
        # 将哈希值转换为整数
        num_val = int.from_bytes(hash_val, byteorder='big')
        # 将整数转换为指定进制的字符串
        str_val = ''
        while num_val > 0:
            num_val, rem = divmod(num_val, radix)
            str_val = str(rem) + str_val
        # 对字符串进行 FPE 加密
        for i in range(rounds):
            str_val = ''.join([chr((ord(c) - ord('0') + i) % (radix - 1) + ord('0')) for c in str_val])
        # 返回加密后的字符串
        return str_val
    
    key = 'my-secret-key'
    encrypted = fpe_encrypt(phone_input, key)
    
    # 将加密后的手机号分成三段
    chunk_size = len(encrypted) // 3
    chunk1 = encrypted[:chunk_size]
    chunk2 = encrypted[chunk_size:2*chunk_size]
    chunk3 = encrypted[2*chunk_size:]
    
    # 在三个 Label 中分别显示加密后的手机号的三段
    phone_label1 = tk.Label(root, text=("加密后的手机号:", chunk1), font=("微软雅黑 -20"))
    phone_label1.place(x=500, y=560)
    phone_label2 = tk.Label(root, text=chunk2, font=("微软雅黑 -20"))
    phone_label2.place(x=500, y=590)
    phone_label3 = tk.Label(root, text=chunk3, font=("微软雅黑 -20"))
    phone_label3.place(x=500, y=620)

这样，加密后的手机号就会分成三行显示。
