今天就是把昨天跟前天做個簡單的整合

import customtkinter

# ========== 設定 Gemini ==========
genai.configure(api_key="你的API KEY")

# ========== 建立 GUI ==========
def button_click():
    input_text = entry.get()
    if input_text.strip() == "":
        output_label.configure(text="⚠️ 請輸入文字！")
        return

    try:
        # 呼叫 Gemini API
        response = model.generate_content(input_text)
        answer = response.text
    except Exception as e:
        answer = f"發生錯誤：{e}"

    # 顯示輸出在 Label
    output_label.configure(text=f"Gemini 回覆：\n{answer}")

# 設定主題外觀
customtkinter.set_appearance_mode("light")

# 建立主視窗
app = customtkinter.CTk()
app.title("Gemini AI 助手")
app.geometry("600x400")

# 標題
title_label = customtkinter.CTkLabel(
    app,
    text="CustomTkinter + Gemini AI",
    text_color="#ff5733",
    font=("timesnewroman", 28, "italic")
)
title_label.pack(pady=20)

# 輸入框
entry = customtkinter.CTkEntry(
    app,

    fg_color="#e0e0e0",
    corner_radius=10,
    width=400

# 提交按鈕

    hover_color="#c8d628",
    text_color="#ffffff",

# 顯示輸出的 Label

    text_color="#333333",
    font=("Arial", 16),

    justify="left"

output_label.pack(pady=20)

app.mainloop()

結果如下圖
