存取CSV

Python 內建 csv 模組，可以輕鬆處理 CSV（逗號分隔值）檔案。

---

✅ 讀取 CSV

import csv

with open("data.csv", newline="", encoding="utf-8") as file:
    reader = csv.reader(file)  # 建立 CSV 讀取器
    for row in reader:
        print(row)  # 逐行讀取並輸出

---

✅ 寫入 CSV

import csv

data = [["姓名", "年齡"], ["小明", 25], ["小華", 30]]

with open("output.csv", "w", newline="", encoding="utf-8") as file:
    writer = csv.writer(file)  # 建立 CSV 寫入器
    writer.writerows(data)  # 寫入多行

📝 總結

• 讀取 CSV → csv.reader(file)
• 寫入 CSV → csv.writer(file).writerows(data)

🚀 簡單易用，適用於處理表格數據！ 😊
