如何學(xué)編程?

編程是編定程序的中文簡(jiǎn)稱,就是讓計(jì)算機(jī)代碼解決某個(gè)問題,對(duì)某個(gè)計(jì)算體系規(guī)定一定的運(yùn)算方式,使計(jì)算體系按照該計(jì)算方式運(yùn)行,并最終得到相應(yīng)結(jié)果的過程。編程能提高邏輯思維能力,加強(qiáng)計(jì)算能力。

編程語言

Python

Python是一種面向?qū)ο笥兄a簡(jiǎn)潔、可讀性強(qiáng)特點(diǎn)的解釋型計(jì)算機(jī)程序設(shè)計(jì)語言。代碼簡(jiǎn)潔是因?yàn)樗言S多的復(fù)雜的操作封裝起來,將C語言中麻煩的指針和內(nèi)存管理對(duì)開發(fā)者隱藏起來,使得在開發(fā)過程中,無須在意這部分的細(xì)節(jié)。另外Python這門語言強(qiáng)制用戶用縮進(jìn)進(jìn)行排版,若不好好排版,則代碼編譯無法通過,或者運(yùn)行過程會(huì)出現(xiàn)錯(cuò)誤。

C語言

C語言是一門面向過程的、抽象化的廣泛應(yīng)用于底層開發(fā)的通用程序設(shè)計(jì)語言,能以簡(jiǎn)易的方式編譯和處理低級(jí)存儲(chǔ)器。C語言既具有高級(jí)語言的特點(diǎn),又具有匯編語言的特點(diǎn),是僅產(chǎn)生少量機(jī)器語言以及不需要任何運(yùn)行環(huán)境支持便能運(yùn)行的高效率程序設(shè)計(jì)語言。

是有簡(jiǎn)潔的語言、具有結(jié)構(gòu)化的控制語句、豐富的數(shù)據(jù)類型、豐富的運(yùn)算符、可對(duì)物理地址進(jìn)行直接操作、代碼具有較好的可移植性、可生成高質(zhì)量、目標(biāo)代碼執(zhí)行效率高的程序。

Java

Java通過面向作為靜態(tài)對(duì)象的編程語言的代表,可以充分的實(shí)現(xiàn)面向的對(duì)象理論的編程語言,有簡(jiǎn)單性、功能強(qiáng)大、分布式、健壯性、安全性、平臺(tái)獨(dú)立與可移植性、多線程及動(dòng)態(tài)性的特點(diǎn)。

Java支持在網(wǎng)絡(luò)上應(yīng)用,Java既支持各種層次的網(wǎng)絡(luò)連接,又以Socket類支持可靠的流(stream)網(wǎng)絡(luò)連接,它是分布式語言。所以用戶可以產(chǎn)生分布式的客戶機(jī)和服務(wù)器。網(wǎng)絡(luò)變成軟件應(yīng)用的分布運(yùn)載工具。Java程序只要編寫一次,就可到處運(yùn)行。

PHP

PHP是一種被廣泛應(yīng)用的開放源代碼的多用途腳本語言,它可嵌入到 HTML中,尤其適合 web 開發(fā)。

使用 PHP 的最大的好處是它對(duì)于初學(xué)者來說極其簡(jiǎn)單,同時(shí)也給專業(yè)的程序員提供了各種高級(jí)的特性,只需幾個(gè)小時(shí)就可以自己寫一些簡(jiǎn)單的腳本。盡管 PHP 的開發(fā)是以服務(wù)端腳本為目的,但事實(shí)上其功能遠(yuǎn)不局限于此。

GO

Go語言(又稱 Golang)是一種靜態(tài)強(qiáng)類型、編譯型語言,是一個(gè)開源編程環(huán)境,可以輕松構(gòu)建簡(jiǎn)單、可靠和高效的軟件。Go 語言語法與 C 相近,但功能上有:內(nèi)存安全,GC(垃圾回收),結(jié)構(gòu)形態(tài)及 CSP-style 并發(fā)計(jì)算。Go 內(nèi)嵌了關(guān)聯(lián)數(shù)組(也稱為哈希表(Hashes)或字典(Dictionaries)),就像字符串類型一樣。

對(duì)比

python和c語言的區(qū)別主要體現(xiàn)在:語言類型、內(nèi)存管理、速度、應(yīng)用、運(yùn)行、對(duì)象、聲明、測(cè)試和調(diào)試難度、復(fù)雜度、學(xué)習(xí)程度。 測(cè)試和調(diào)試難度不同:Python相對(duì)其他語言而言是非常簡(jiǎn)單的語言,高度集成,代碼量少。Python中的測(cè)試和調(diào)試更容易;C中測(cè)試和調(diào)試更難。 學(xué)習(xí)難度不同:Python:Python程序更易于學(xué)習(xí),編寫和閱讀;C語言:C程序語法比Python更難。

python 跟 java 一樣是強(qiáng)類型語言,也就是說它不會(huì)根據(jù)環(huán)境變化自動(dòng)改變數(shù)據(jù)類型。python 是動(dòng)態(tài)語言,而 java 是靜態(tài)語言。也就是說 python 在編程時(shí),永遠(yuǎn)不用給任何變量指定數(shù)據(jù)類型,而 java 寫程序時(shí)必須聲明所有變量的數(shù)據(jù)類型。

python 的模塊類似于 java 的 class,不過python模塊導(dǎo)入會(huì)執(zhí)行 代碼的內(nèi)容,而 java 不會(huì)。python 與 java 的執(zhí)行方式還是蠻像的,都是將源碼編譯成 byte code 然后交給相應(yīng)的虛擬機(jī)去執(zhí)行。

Python的框架數(shù)量較少,而PHP中成熟的框架比較多;PHP是面向web的語言,而Python是多用途語言,也可以用于web開發(fā);Python使用非常嚴(yán)格的縮進(jìn)強(qiáng)制執(zhí)行,使它比PHP更具可讀性。

學(xué)習(xí)思路

認(rèn)識(shí)編程

編程語言(programming language)又稱程序設(shè)計(jì)語言,是一組用特定語言編寫的用于執(zhí)行特定任務(wù)的指令。主要用于開發(fā)桌面應(yīng)用、操作系統(tǒng)、網(wǎng)站、移動(dòng)應(yīng)用等。

低級(jí)編程語言

它基于二進(jìn)制數(shù) 0 和 1 工作,處理器直接運(yùn)行低級(jí)程序,不需要編譯器或解釋器,因此用低級(jí)語言編寫的程序可以運(yùn)行得非???。

低級(jí)語言進(jìn)一步分為兩部分

機(jī)器語言

機(jī)器語言也稱為機(jī)器代碼或目標(biāo)代碼,更容易閱讀,因?yàn)樗ǔR远M(jìn)制或十六進(jìn)制形式(基數(shù) 16)形式顯示。

它不需要翻譯器來轉(zhuǎn)換程序,因?yàn)橛?jì)算機(jī)直接理解機(jī)器語言程序。

匯編語言

匯編語言是為特定處理器設(shè)計(jì)的,它以象征性和人類可理解的形式表示一組指令。它使用匯編程序?qū)R編語言轉(zhuǎn)換為機(jī)器語言。

中級(jí)編程語言

中級(jí)編程語言介于低級(jí)編程語言和高級(jí)編程語言之間。

它也被稱為中間程序語言和偽語言。

中級(jí)編程語言的優(yōu)點(diǎn)是支持高級(jí)編程的特性,是一種用戶友好的語言,與機(jī)器語言和人類語言密切相關(guān)。

例如:C、C++

高級(jí)編程語言

高級(jí)編程語言 (HLL) 旨在開發(fā)用戶友好的軟件程序和網(wǎng)站。

這種編程語言需要編譯器或解釋器將程序翻譯成機(jī)器語言(執(zhí)行程序)。

示例:Python、Java、JavaScript、PHP、C#、C++ 等。

編程實(shí)踐

學(xué)習(xí)編程語言的過程簡(jiǎn)單描述為:過、抄、仿、改、調(diào)、看、練、創(chuàng)、悟。

基礎(chǔ)知識(shí)點(diǎn)不求深解,語言什么樣的,適用場(chǎng)合、基本語法格式

抄代碼

從書上抄、例子中抄、邊抄邊想邊想邊回憶語法

模仿改

仿照給出的代碼寫出自己的代碼

勤調(diào)試

不斷調(diào)試驗(yàn)證自己想法,繼續(xù)思考,再次驗(yàn)證。熟悉調(diào)試工具調(diào)試方法

看n遍

出錯(cuò)或者遇到問題時(shí),將代碼從頭到尾看n遍直到快記住,找出問題原因

2-5步三遍以上

創(chuàng)新

拿出一個(gè)沒有寫過的根據(jù)要求,一步一步寫出來,寫不出來參考6

主動(dòng)找到寫代碼的感覺和成就感,保持下去。

選擇大于努力,只有切入一個(gè)適合自己的開發(fā)方向,才能持續(xù)進(jìn)步。關(guān)于開發(fā)方向,我有以下兩個(gè)選擇標(biāo)準(zhǔn)。

興趣

學(xué)習(xí)編程是一個(gè)非??菰锏倪^程,內(nèi)容多,時(shí)間長(zhǎng),成本高,即使報(bào)名了培訓(xùn)班也學(xué)不會(huì),所以,我們首先要選擇自己感興趣的一個(gè)開發(fā)方向,這樣不但能快速學(xué)習(xí),以后還能持續(xù)進(jìn)步。學(xué)習(xí)編程的過程是比較艱苦的,沒有興趣很難硬抗下來,此處的興趣,是指別人無法撼動(dòng)的熱愛,是工作之余讓你放松的事情。如果你只是有過某種想法,別人告訴你這個(gè)想法不靠譜,你就放棄了,這頂多是一時(shí)的雞血。

學(xué)習(xí)方式

費(fèi)曼學(xué)習(xí)法

在學(xué)完一個(gè)東西之后去給別人講明白,注意是講給別人聽,當(dāng)你寫成文章發(fā)表在網(wǎng)上的時(shí)候,你自然會(huì)去用更通俗的語言,更清晰的邏輯去講述這個(gè)事物背后的邏輯。這個(gè)過程是對(duì)自己學(xué)習(xí)的一個(gè)檢驗(yàn),也是加深映像整理思路的重要過程。

那么如果你是去記筆記的話,很有可能你會(huì)傾向于去照抄,或是不完全照抄,以“提綱”或是“知識(shí)點(diǎn)”的形式抄在本子上。說句實(shí)話,照抄的筆記真的沒用,因?yàn)楝F(xiàn)在搜索引擎的能力已經(jīng)可以讓你把大多數(shù)東西快速找到,你為什么還要照抄到筆記本上呢?

從功利的角度考慮,技術(shù)文章的寫作,別人可以直接訪問,也可以逐漸累積你的影響力,一個(gè)好的個(gè)人技術(shù)博客,會(huì)給你的簡(jiǎn)歷加分很多,而一個(gè)厚厚的筆記本,沒有人會(huì)管你記了什么。

做好筆記

大多數(shù)人沒有過目不忘的神技,學(xué)了也不一定馬上掌握,需要過后花時(shí)間慢慢領(lǐng)悟,而且還有忘掉的風(fēng)險(xiǎn),所以對(duì)于重要的知識(shí)點(diǎn)都要做好筆記。編程的過程中總會(huì)遇到各種各樣的問題,比如編程環(huán)境的配置,常用的快捷鍵,編程過程中的錯(cuò)誤、異常,軟件更新問題等等。面對(duì)這些問題都是如何解決的,一定要記錄下來,一是增加自己解決問題的經(jīng)驗(yàn),而是以防下次出現(xiàn)。

多看官方文檔

外文資料互聯(lián)網(wǎng)是一個(gè)更新迭代很快的行業(yè),所有編程語言都會(huì)不斷的更新新功能和修復(fù)舊Bug,網(wǎng)上查的資料很有可能是舊的解決方案,現(xiàn)在已經(jīng)不適用了。所以最好最快的方法就是查看官方文檔。

進(jìn)入行業(yè)圈子

只有進(jìn)入行業(yè)圈子與其他人交流,你才了解最新的行業(yè)動(dòng)態(tài),才知道自己需要更新哪些技能。

動(dòng)手做項(xiàng)目

學(xué)習(xí)編程的最終目的就是用所學(xué)的做出具有一定功能的項(xiàng)目,而做項(xiàng)目又是最好的學(xué)習(xí)和鞏固知識(shí)的方式。如果前期能力不足就先做一些簡(jiǎn)單的功能模塊,一步一步慢慢來,不要一開始就要實(shí)現(xiàn)各種酷炫炸天功能,遇到不會(huì)的就在網(wǎng)上查, 現(xiàn)在互聯(lián)網(wǎng)這么發(fā)達(dá),獲取資源也及其方便。而且開發(fā)前也最好在網(wǎng)上查一下有沒有已經(jīng)成型的框架或模板,什么都自己做一是很耗費(fèi)時(shí)間,二是自己技術(shù)能力不足還可能留下不少坑。

學(xué)習(xí)Python

安裝編程環(huán)境

第一步:訪問Python官網(wǎng),獲取最新安裝程序。

第二步:運(yùn)行下載的安裝程序,注意勾選“Add Python3.7 to PATH”,然后選擇個(gè)性化安裝,即“Customize installation”。

第三步:確?!皃ip”被勾選上,之后安裝各種庫需要用到pip。

第四步:高級(jí)選項(xiàng),需要的可以修改安裝目錄,通常沒有需要修改的,直接點(diǎn)“Install”。

第五步:等待程序自動(dòng)安裝完成。

第六步:出現(xiàn)如下界面,說明安裝已完成。

第七步:驗(yàn)證方法,Windows+R 鍵打開“運(yùn)行”窗口,輸入cmd運(yùn)行,進(jìn)入命令提示窗口,再輸入python,進(jìn)入Python的命令模式,輸入 print("Hello"),結(jié)果輸出了 Hello,如下圖所示,確定開發(fā)環(huán)境已安裝完成。

運(yùn)行環(huán)境

Hello World!

命令行

在Linux命令行輸入:$python

將直接進(jìn)入python。然后在命令行提示符>>>后面輸入:>>>print('Hello World!')

可以看到,隨后在屏幕上輸出:

Hello World!

print是一個(gè)常用函數(shù),其功能就是輸出括號(hào)中得字符串。

(在Python 2.x中,print還可以是一個(gè)關(guān)鍵字,可寫成print 'Hello World!',但這在3.x中行不通 )

小程序

另一個(gè)使用Python的方法,是寫一個(gè)Python程序。用文本編輯器寫一個(gè).py結(jié)尾的文件,比如說hello.py

在hello.py中寫入如下,并保存:print('Hello World!')

退出文本編輯器,然后在命令行輸入:$python hello.py

來運(yùn)行hello.py??梢钥吹絇ython隨后輸出Hello World!

腳本

我們還可以把Python程序hello.py改成一個(gè)可執(zhí)行的腳本,直接執(zhí)行:#!/usr/bin/env python

print('Hello World!')

需要修改上面程序的權(quán)限為可執(zhí)行:chmod 755 hello.py

然后再命令行中,輸入./hello.py

就可以直接運(yùn)行了。

基本數(shù)據(jù)類型

變量不聲明

Python的變量不需要聲明,你可以直接輸入:>>>a = 10

那么你的內(nèi)存里就有了一個(gè)變量a, 它的值是10,它的類型是integer (整數(shù))。 在此之前你不需要做什么特別的聲明,而數(shù)據(jù)類型是Python自動(dòng)決定的。

>>>print(a)

>>>print(type(a))

那么會(huì)有如下輸出:

10

這里,我們學(xué)到一個(gè)內(nèi)置函數(shù)type(),用以查詢變量的類型。

回收變量名

如果你想讓a存儲(chǔ)不同的數(shù)據(jù),你不需要?jiǎng)h除原有變量就可以直接賦值。

>>>a = 1.3

>>>print(a,type(a))

會(huì)有如下輸出

1.3

序列

sequence(序列)是一組有順序的元素的集合,(嚴(yán)格的說,是對(duì)象的集合,但鑒于我們還沒有引入“對(duì)象”概念,暫時(shí)說元素)序列可以包含一個(gè)或多個(gè)元素,也可以沒有任何元素。

我們之前所說的基本數(shù)據(jù)類型,都可以作為序列的元素。元素還可以是另一個(gè)序列,以及我們以后要介紹的其他對(duì)象。

序列有兩種:tuple(定值表; 也有翻譯為元組) 和 list (表)

>>>s1 = (2, 1.3, 'love', 5.6, 9, 12, False) # s1是一個(gè)tuple

>>>s2 = [True, 5, 'smile'] # s2是一個(gè)list

>>>print(s1,type(s1))

>>>print(s2,type(s2))

tuple和list的主要區(qū)別在于,一旦建立,tuple的各個(gè)元素不可再變更,而list的各個(gè)元素可以再變更。

一個(gè)序列作為另一個(gè)序列的元素

>>>s3 = [1,[3,4,5]]

空序列

>>>s4 = []

自學(xué)

網(wǎng)站

菜鳥網(wǎng)站

這個(gè)python教程很適合小白學(xué)習(xí),沒有高深的原理,照著教程學(xué)就完事了。

菜鳥教程是一個(gè)提供免費(fèi)編程學(xué)習(xí)的網(wǎng)站,里面不但能學(xué)到編程知識(shí),還能運(yùn)用在線編程工具,使你在學(xué)習(xí)的過程中得到發(fā)揮,實(shí)踐得真理,邊學(xué)邊做中讓基礎(chǔ)打得更穩(wěn),讓自己的知識(shí)更加穩(wěn)固。在自己有不明白不理解的地方可以在網(wǎng)站的用戶筆記中尋找大佬們的筆記,把自己所學(xué)和技術(shù)大佬的經(jīng)驗(yàn)所融合,使自己更好地提升自己的能力。

菜鳥教程內(nèi)容豐富,例如前端熱門語言HTML5、CSS3、JavaScript、Vue等它該有的都有,都會(huì)從最基礎(chǔ)的開始教,讓剛學(xué)編程的小白由淺及深,一看就懂。每個(gè)知識(shí)點(diǎn)都有實(shí)例可以動(dòng)手,直接在頁面內(nèi)做你想要的效果真的非常棒。菜鳥的排版簡(jiǎn)潔清晰有序,內(nèi)容一針見血,讓你一看就能明白其知識(shí)點(diǎn)的含義。

菜鳥教程不僅前端教程語言豐富,后端的Java、PHP、Python更是一應(yīng)俱全,當(dāng)然數(shù)據(jù)庫、移動(dòng)端、XML、ASP.NET、Web Service、開發(fā)工具和網(wǎng)站建設(shè)也是應(yīng)有盡有,菜鳥教程有學(xué)到的知識(shí)如此之多,奮斗吧少年。

廖雪峰的官方網(wǎng)站

廖雪峰的官方網(wǎng)站比較推薦新手程序員學(xué)習(xí)前端,這個(gè)網(wǎng)站的教學(xué)視頻的講解相對(duì)來說會(huì)比較生動(dòng),沒有其他教程那么死板,看起來也不至于那么犯困,也更便于新手去理解。總的來說,廖雪峰的官方網(wǎng)站作為一款啟蒙類的前端學(xué)習(xí)網(wǎng)站還是相當(dāng)不錯(cuò)的。

Python官方教程

這是Python官方出品的教程,可搭配Python標(biāo)準(zhǔn)庫一起學(xué)。
