二.資料簡介
《21天學(xué)通Python》全面、系統(tǒng)、深入地講解了Python編程基礎(chǔ)語法與高級應(yīng)用。在講解過程中，通過大量實際操作的實例將Python語言知識全面、系統(tǒng)、深入地呈現(xiàn)給讀者。此外，作者專門為本書錄制了大量的配套教學(xué)視頻，讓讀者通過分析實例、運行實例盡快熟悉Python編程，在學(xué)習(xí)中遇到問題時，也可以作為參考。
《21天學(xué)通Python》共分三篇。第一篇介紹Python語言的特點、安裝、語法基礎(chǔ)、程序流程控制、面向過程的編程方法、面向?qū)ο蟮木幊谭椒?、程序異常的處理；第二篇介紹了Python語言中的包與模塊、迭代器、生成器、裝飾器、上下文管理器等進(jìn)階語法，同時介紹了使用Python標(biāo)準(zhǔn)庫中的文件系統(tǒng)處理、圖形化界面編程、正則表達(dá)式、網(wǎng)絡(luò)編程、多進(jìn)（線）程編程、數(shù)據(jù)庫編程。此外，還介紹了運用第三方庫的Web網(wǎng)站編程、圖片處理；第三篇通過兩個案例介紹Python的綜合編程技術(shù)。
《21天學(xué)通Python》在內(nèi)容上涉及面廣，從基本操作到高級技術(shù)及綜合案例，涉及Python語言的基礎(chǔ)語法和編程特性。《21天學(xué)通Python》在設(shè)計上淺顯易懂、實例豐富，尤其適合廣大編程初學(xué)者自學(xué)，也適合對Python語言感興趣的愛好者作為參考用書。
三.作者簡介
本書的作者團(tuán)隊成員為一線開發(fā)工程師、資深編程專家或?qū)I(yè)培訓(xùn)師，在編程開發(fā)方面有著豐富的經(jīng)驗，并已出版過多本相關(guān)暢銷書，頗受廣大讀者認(rèn)可。長期積累的開發(fā)實戰(zhàn)經(jīng)驗，結(jié)合對編程入門愛好者需求與特點的深入調(diào)查研究，本書的內(nèi)容結(jié)構(gòu)十分有利于編程愛好者和相關(guān)學(xué)員快速提高水平。
