我不是資工系、不是理工科、不是…，當你想學程式語言卻好像有好多條件不符的障礙，想學程式語言卻又猶豫不決，怕自己學不來，下定決心想投入學習後，卻又在茫茫的程式語言爆炸資訊當中，載浮載沉，不知道從哪開始著手。

對於沒有背景的程式語言學習者，Python是個很好的入門語言，而且應用也相當廣泛，本文將介紹9個Python應用面向，想快速閱讀的朋友，可以使用快速閱讀目錄點擊到你有興趣的地方閱讀。

為什麼選Python？

Python被稱為最容易上手、學習門檻低的程式語言:
怎麼說呢？因為Python屬於高階程式語言，跟人類習慣的語法比較接近，容易撰寫跟除錯，相對其他程式語言(如C語言)當然就容易學習許多。

Python容易上手，有利於培養對學習程式語言的興趣:
瞭解自己對寫程式是不是有興趣，若有興趣，可以更深入專研Python，且從Python上學到的邏輯基礎，也可以讓我們更快的上手其他程式語言；而若只是被程式熱的風潮影響，對程式語言沒有興趣，Python讓你投入的成本與時間相對很少。

Python是全球最受歡迎的程式語言之一:
從2021年9月TIOBE編程社區索引所列的程式語言受歡迎程度表來看，Python排名僅次於C語言，而且Python的應用多、資源多、支援多，發展空間大、學習資源豐富此外大量的函式庫，讓工程師可以更快的完成工作。(函式就是一段程式，這段程式有名稱，並可以執行一些操作。)
