This book is designed with localized content aiming at cultural comparison and language learning for communication. The ten lessons are threaded by an interesting story, introducing cultural highlights of Taiwan and India through cross-culture comparison.

Dylan was six when The End came, back in 2018; when the electricity went off for good, and the 'normal' 21st century world he knew disappeared. Now he's 14 and he and his mam have survived in their isolated hilltop house above the village of Nebo in north-west Wales, learning new skills, and returning to old ways of living. Despite their close understanding, the relationship between mother and son changes subtly as Dylan must take on adult responsibilities. And they each have their own secrets, which emerge as, in turn, they jot down their thoughts and memories in a found notebook - the Blue Book of Nebo. In this prize-winning novel, Manon Steffan Ros not only explores the human capacity to find new strengths when faced with the need to survive, but also questions the structures and norms of the contemporary world.

內容介紹: 【最齊全！徹底活用Pandas的114技】想學Pandas，看官方文件就夠了？對於Python使用者來說，Pandas無疑是資料分析的必備套件。有了Pandas，您可以非常高效地重塑、過濾、清理以及整合大部分類型的資料。的確，Pandas的官方網站提供了不同指令的使用範例。因此有的使用者會說：『不用買書看啦！網路資源這麼豐富，多看看官方文件就好了！』不過，單單只知道某個指令的運作方式是不足夠的。在實際進行資料分析時，您可能需要結合多個指令來達成目標。這時候，您更需要知道如何活用Pandas。舉例來說，假設您現在面對DataFrame的記憶體用量過大，導致無法順利分析資料的難題時，該怎麼辦呢？從Pandas的官方文件中，您可以了解轉換欄位型別的方法，也知道如何查詢欄位的浮點數精度。只要結合這兩個方法，您就可以非常輕鬆地降低DataFrame的記憶體用量。遺憾的是，官方文件並不會告訴您這個訣竅，而必須自己花時間來摸索。在摸索的過程中，不可避免地會多走許多彎路。本書並非單純的Pandas語法參考手冊。作者寫作此書時的目標，是希望讀者們可以從完整的範例中學習，並充分了解活用Pandas技巧的重要性。此外，作者習慣給出同一問題的不同解法，同時比較不同做法的效能。由此一來，讀者日後在實際分析資料時，才能知道哪一種做法是最優解。正面對決真實資料集！目前市面上的Pandas書籍，多數是使用亂數產生的假資料集來進行教學。這會導致您在面對真實資料集時，不知該從何下手。有鑒於此，本書作者使用了眾多的真實資料集，讓讀者切身感受資料分析師的工作內容。書中的資料集包含：●IMDB 5000電影資料集●Tesla股票資料集●Kaggle問卷資料集●鑽石品質資料集●美國大學資料集●美國國內航班資料集●丹佛市的犯罪案件資料集 ●阿爾塔年積雪資料集●美國燃油經濟資料集 …等最齊全的Pandas技巧教學！為了讓讀者可以更好的理解，書中每一小節的內容皆搭配完整範例。讀者可以從讀入資料集開始，循序漸進地搞懂資料分析的眉眉角角。全書共傳授了Pandas實戰的114種技巧，保證讀者可以全面掌握其中的精髓。讀者將會學到如何：●處理資料集中的缺失值●處理索引爆炸的問題●組合多個Pandas物件●在DataFrame中新增和刪除欄位●取得特定欄位的統計資訊●轉置DataFrame的運算方向●
