開發社區您好！我是 Andre，一位熱衷於深入 Python 世界的初學者程式設計師。在與動力鬥爭了幾年之後，我決定將注意力轉移到建立真正的專案上。今天，我想分享關於創建我的第一個 Python 專案的故事：個人支出追蹤器 (PET) 應用程式。 （代碼在最後）
個人開支追蹤器是一款命令列應用程序，旨在幫助用戶記錄日常開支、對其進行分類並深入了解他們的消費習慣。我的目標是創建一個工具，使用戶能夠控制自己的財務。 （還有我的！啊哈）
我面臨的最重大挑戰之一是弄清楚如何有效地儲存費用資料。我最初在 Python 中處理文件時遇到了困難，但經過一番堅持，我終於實現了一個可行的解決方案！
透過這個項目，我了解了使用者輸入驗證和確保資料記錄一致的重要性。我還獲得了使用 Python 管理文件以儲存和檢索費用記錄的寶貴經驗。
展望未來，我計劃整合資料視覺化功能，幫助使用者直觀地看到他們的消費模式。另外，我很高興能夠實現一個預算工具，允許用戶按類別設定支出限額。
完成個人支出追蹤器是一次非常有益的經歷，增強了我作為開發人員的信心。我渴望繼續我的後端開發和 DevOps 學習之旅，更多專案即將到來！
我很想聽聽您的回饋！如果您建立了類似的東西或有增強費用追蹤器的技巧，請分享您的見解！
