Adobe Premiere是Adobe家族的一款剪輯軟件，它給我的感覺就是入門快,、功能強大,，無論是對于新手還是專業(yè)人士，PR在大部分情況下都是很友好的,。

認識PR

Pr全稱Adobe Premiere,，是Adobe公司開發(fā)的一款視頻剪輯&編輯軟件,。主要用于視頻采集、視頻剪輯,、調(diào)色,、添加字幕、編輯音頻,、渲染輸出,。

Premiere提供了采集、剪輯,、調(diào)色、美化音頻,、字幕添加,、輸出、DVD刻錄的一整套流程,，并和其他Adobe軟件高效集成,，使用戶足以完成在編輯、制作,、工作流上遇到的所有挑戰(zhàn),，滿足用戶創(chuàng)建高質(zhì)量作品的要求。

下載PR軟件

Adobe官網(wǎng)下載

進入Adobe官網(wǎng)進行下載https://www.adobe.com/cn/products/premiere.html

其他網(wǎng)頁下載

1,、打開瀏覽器今日頭條搜索3D溜溜網(wǎng),，進入官網(wǎng)

2、打開瀏覽器搜索3D溜溜網(wǎng),，進入官網(wǎng),，點擊上面【···】三個點之后選擇【軟件插件】里的【羽兔網(wǎng)軟件下載】

3、選擇【常用軟件】里的【視頻制作】

4,、向下滑,，在下面找到PR2018版本的進行【軟件下載】，里面還有其他版本,，這里選擇的是適配win7的,。

PR窗口介紹

Premiere軟件由菜單欄、常用工具欄,、時間軸,、側(cè)邊面板欄（組件窗口）組成。主工作區(qū)有素材（項目）管理窗口,、素材預覽窗口,、視頻監(jiān)視器窗口、時間軸窗口,、調(diào)音臺窗口,、調(diào)色窗口等,。

菜單欄

菜單欄可以說是整個軟件的功能導圖,，為軟件中大多數(shù)功能提供了菜單入口,，例如PR軟件中的絕大多數(shù)功能在對應的菜單欄中都可以找到,。

功能窗口切換區(qū)域:(組件,、編輯,、顏色,、效果,、音頻,、字幕,、庫......)

功能窗口切換區(qū)域是軟件為剪輯,、調(diào)色、音頻,、字幕等不同功能定義的界面布局方案,。點擊對應的功能，軟件會自動切換到使用該功能時的界面布局,。

源素材預覽窗口

源窗口主要是為項目面板中素材(視頻,、音頻、圖片)提供實時預覽,，雙擊項目面板中的素材即可在源窗口中進行播放預覽,。

節(jié)目監(jiān)視窗口

節(jié)目窗口主要用于監(jiān)視時間線上剪輯的畫面，可以實時播放,。

項目面板

項目面板主要是用于項目及素材的管理,，我們導入到軟件中的素材及新建的序列、字幕等素材全部都存放在項目面板中,。

時間線窗口

時間線窗口可以簡單理解為剪輯工作臺,，我們對素材的剪輯工作全部都是在時間線面板中操作完成。時間線窗口又可分為視頻軌道和音頻軌道,。

工具欄

工具欄集合了所有視頻剪輯工具,，當然有一些是輔助剪輯工具。

選擇工具（快捷鍵：V）

顧名思義,，它的作用就是用來選擇東西的,，不過在有的時候它也會變?yōu)槠渌男螤睿饔靡搽S之改變,。

向前選擇軌道工具（快捷鍵：A）

使用此工具可以選擇該軌道上以后的所有素材,，視音頻鏈接在一起的則音頻同時也被選中；按住Shift鍵可以變?yōu)槎嘬壍肋x擇工具,，此時單頭變?yōu)殡p頭,，即使是單獨的聲音（比如音效、音樂等）也會被同時選中。

波紋編輯工具（快捷鍵：B）

使用此工具可以改變一段素材的入點和出點,，這段素材后面的會自動吸附上去,，總長度發(fā)生改變。

剃刀工具（快捷鍵：C）

pr中導入素材之后,，利用剃刀工具切割開視頻,，視頻就分開為多段了，可以分別剪輯切割后的每一段視頻,，包括刪除,、添加效果等。

外滑工具（快捷鍵：U）

作用于一段素材,，用來同時改變此段素材的入點和出點,。

鋼筆工具（快捷鍵：P）

這個工具和字幕中的鋼筆工具是一樣，主要用來繪制形狀,。選中此工具,，在需要的位置點擊一下確定起點，直接點其它位置可以繪制直線,，而在點第二個點的同時按住鼠標不放并進行拖拽可以繪制曲線；它還有一個作用就是進行關(guān)鍵幀的選擇,。

手形工具（快捷鍵：H）

點擊鼠標左鍵,，在時間軸上拖動，移動時間軸上顯示素材的位置,。當程序監(jiān)視器放大時,。拖放程序監(jiān)視器中的可移動顯示區(qū)域以觀察細節(jié)。

文字工具（快捷鍵：T）

文字工具即在畫面中輸入我們想要的文字,。

效果面板

效果面板集合了很多視頻和音頻效果控件,，對視頻或者音頻添加模糊及轉(zhuǎn)場等效果時，需要在效果面板中找到對應的效果控件然后添加到時間線上的剪輯,。

效果控件面板

效果控件面板是對已經(jīng)添加到素材上的效果進行參數(shù)調(diào)節(jié)的窗口,。

音軌混合器窗口

對音頻進行聲道和音量調(diào)節(jié)的窗口，當然也可以通過這個窗口進行現(xiàn)場錄音,。

PR剪輯教程

創(chuàng)建項目

首先新建項目,，暫存盤里的地址欄跟項目一樣就可以。

新建序列

新建序列,，選擇1080p25,，點擊確定，就建立了一個時間線,。

一般的剪輯軟件里邊都有現(xiàn)成的預設,，只要知道這個尺寸就行，高清格式選擇1080P或者720P都行,。

導入素材

在項目列表雙擊,，找到我們的素材,，按住shift一塊兒導入，導入之后可以對素材進行分類,，讓我們可以看的更仔細一些,。（養(yǎng)成一個好的分類習慣，有助于提高我們工程的有趣性和效率,，以后打包工程的整理都非常的有好處）,。

拖入時間線

素材分類好之后，把視頻音頻素材按住shift一起都拖拽到時間線里,。

設置比例

發(fā)現(xiàn)視頻素材的大小不一,，我們調(diào)整視頻整體比例大小。找到信息,，看見比例為640*360,，在我們新建的時候不是這個比例，我們在序列里進行更改設置為640*360,，這樣時間線就跟我們相匹配了,。

編輯視頻

導入素材之后，我們開始對視頻進行剪輯,。

添加效果

添加效果,，讓視頻看起來更流暢。

添加字幕

添加結(jié)尾字幕,。

導出

剪輯完成,，導出成品。

PR導出格式一般用MOV,、mp4,、AVI等等。PR輸出視頻的時候,，要求不一樣,，輸出的格式的就不一樣。因為沒有統(tǒng)一的標準,，要根據(jù)需求和目的才能定什么是合適的,。

1、如果想輸出文件后繼續(xù)進行編輯,，一般推薦輸出MOV,。

2、如果輸出文件后直接就要觀看,，或傳到視頻網(wǎng)站,。推薦輸出H.264，即mp4。

3,、如果輸出文件給電視臺標清播出,，就輸出AVI格式。

成品

下面這張是成品

這里用的是PR2018版本

PR基礎(chǔ)快捷鍵

1,、按i可以設置入點,，O可以設置出點。

2,、Shift+delete鍵可以刪除視頻同時,，把視頻之間的間隙去掉；Ctrl+Z撤銷,。

3,、向前選擇軌道工具（A）和鏈接選擇項的結(jié)合使用可以刪除選擇點后面的視頻和音頻

4、向前選擇軌道工具（A）和取消鏈接選擇項的結(jié)合使用按shift鍵可單獨刪除視頻,，保留音頻,。

5、按Q鍵可刪除剪輯的開始,，按W鍵可刪除剪輯的結(jié)尾,，但是它們會從每個音軌中刪除內(nèi)容，如果有多層音軌,，這個快捷鍵就不適用,，可以通過鎖定音頻軌道來避免音頻被刪除。

6,、按光標鍵→，按一下前進一幀,，按Shift鍵+光標鍵,，一下會前進5幀。

7,、alt+拖動素材=復制

常用的快捷鍵如下：

注：如果自己不適應默認的快捷鍵可以在PR界面快捷鍵設置修改,，步驟如下：

打開快捷鍵界面有兩種方法：第一種方法，打開PR后,，在菜單欄找到編輯選項下的快捷鍵菜單,，單擊后就會彈出設置界面。第二種方法,，打開PR后,，我們直接使用快捷鍵Ctrl+Alt+K后，也會彈出設置界面,。

打開快捷鍵界面后在搜索框里我們直接輸入想要添加的快捷鍵功能,，然后在空白處單擊鼠標，就會產(chǎn)生一個框，按下要設置的快捷鍵,，最后點擊確定保存設置,，這樣就快捷鍵就設置好了。

PR視頻特效

添加濾鏡

首先就是濾鏡的位置是在左下角的【效果】選項里面,，如下圖箭頭指向所示：

里面的濾鏡很多,，可以選擇自己喜歡的濾鏡進行使用，如下圖箭頭指向所示：

然后,，我們直接將濾鏡拖拽到素材身上就可以進行使用了,，如下圖箭頭指向所示：

調(diào)整濾鏡的內(nèi)部可調(diào)節(jié)參數(shù)，素材的效果就能實時預覽,。點擊前面的【FX】可以進行濾鏡效果的開啟以及關(guān)閉,，如下圖箭頭指向所示：

效果里面，除了視頻濾鏡,，還有音頻濾鏡以及各種轉(zhuǎn)場可用,，如下圖箭頭指向所示：

添加字幕

在工具欄，點擊文字工具,；

使用文字工具點擊視頻,，在文字框中輸入字幕，就添加字幕成功了,。

視頻的刪減

導入完素材之后我們將素材拖到右邊,，便能對視頻素材進行編輯了（點擊播放按鈕可預覽）。接下來我們講一下視頻內(nèi)容的刪減,。

比如說：我們覺得某一段內(nèi)容不好,，想把它刪掉，那么該怎么辦呢,？在PR中我們有兩種方法：

1,、選擇左側(cè)工具欄的刻刀工具，在想要刪去內(nèi)容的兩頭進行點擊,，然后即可將商品分割成三段,，可從中選擇自己不想要的內(nèi)容；

2,、直接從末尾拖動即可（只能對開頭或末尾內(nèi)容進行刪減）,。

視頻的倍速播放

視頻的倍速播放在PR中很容易就能實現(xiàn)了：右鍵-速度/持續(xù)時間。選擇速度（百分比,，如200%就是兩倍速） ,，點擊【倒放速度】就能倒放了。

音樂淡出效果

添加音樂的方法和添加視頻的方法一樣,，導入以后拖動到右邊就可以了,。刪減運用上述方法也是可以完成的,。

音樂淡出的效果：

添加完音頻后，拉開軌道,，點擊左下的小按鈕,，選擇：軌道關(guān)鍵幀-音量；

選擇：添加-移除關(guān)鍵幀按鈕,，在想要淡入,、淡出的地方添加關(guān)鍵幀，即可對音量進行修改,，完成淡入,、淡出的效果；

如果你是第一次使用PR并且佩戴耳機的話,，要到PR的【編輯】-【首選項】-【音頻硬件】里的【默認輸出】修改輸出設備為：耳機,。

音效增益

打開PR軟件，將音頻導入進去,，拖到右下方的【時間軸】操作區(qū),；

右擊鼠標，點擊音軌,，在出現(xiàn)的選項中點擊【音頻增益】,；

在【音頻增益】頁面，選擇【將增益設置為】,；

輸入合適的音頻值,，負數(shù)表示減少，完成后點擊【確定】,。

視頻轉(zhuǎn)場

首先打開電腦上的PR,，打開項目文件后，選擇右側(cè)的【效果】面板,，效果面板中有音頻效果,、音頻過渡，視頻效果,、視頻過渡；

鼠標點開【視頻過渡】,，其中有7類轉(zhuǎn)場特效,，我們這里點擊進入【溶解】，選擇【溶解】下的【交叉溶解】,；

選擇【交叉溶解】拖動到視頻上,，可以看到我們可以將轉(zhuǎn)場放置到視頻末尾，視頻開頭或兩段視頻中間,，這里選擇【視頻中間】,；

插入完成后我們雙擊此轉(zhuǎn)場,，進入【設置過渡持續(xù)時間】，拖動藍色字體即可增加或減少時間,。

4. 鉆井鉆具容積

三刃的一般為高速切削鉆頭,，但是材質(zhì)一定要好,，一般為合金材質(zhì)的

牙輪鉆頭主要靠敲擊,、壓碎破巖、輔以剪切破巖,，而金剛石鉆頭主要靠剪切,、切削破巖，輔以壓碎破巖,、齒出露短,，刃口鋒利，因此金剛石鉆頭的鉆壓小,，轉(zhuǎn)速高,，排量小。

金剛石鉆頭的鉆壓小有利于防斜,。牙輪鉆頭由于牙輪的移軸,、超頂、復錐結(jié)構(gòu),，且牙輪與本體有一定的相對位移量,，從而橫向移距r′金＜r牙。

金剛石鉆頭克服這種不平衡的橫向力效果好些,，這也有利于防斜。金剛石鉆頭與牙輪鉆頭在使用上也有不同之處,，應針對不同層段,，選好鉆頭類型。如嘉陵江和飛仙關(guān)層段用BDC的S248鉆頭,；在高密度鉆井液條件下盡量用金剛石鉆頭,。使用金剛石鉆頭前井眼要暢通、干凈,，調(diào)好鉆井液性能,，檢查設備和鉆具，選好參數(shù),。金剛石鉆頭單只壽命長,，從而起下鉆時間少，但它不能有效地鉆進含燧石,，黃鐵礦和硅質(zhì)的不均質(zhì)堅硬地層,。

所以，應與牙輪鉆頭配合,，采用“銜接使用法”,。 (1)經(jīng)理論分析和現(xiàn)場實踐，兩種鉆頭各有特點,，選用時應針對地層和鉆井液密度,，充分發(fā)揮各自的優(yōu)勢,，優(yōu)選鉆頭和參數(shù)，使其發(fā)揮最佳破巖效果,。

(2)金剛石鉆頭的剪切破巖基本消除了牙輪鉆頭的牙齒敲擊,、壓碎巖石所帶來的“壓持效應”的重復切剪，能在高密度井段保持高機械鉆速,。

(3)金剛石鉆頭的輕鉆壓和高轉(zhuǎn)速

5. 鉆井平臺大小

一：流量一般要求在每小時30噸以內(nèi),，深度約40-80米，鉆機開口直徑約30厘米,，下放井壁管直徑160mm,、200mm，抽功率為1.1-7.5KW潛水深水泵,，井壁管規(guī)格為160mmx4mmx4000mmPVC定制管有檢驗報告等管材堅硬管材仍能承受強側(cè)壓,，附取水管帶一整套透水過濾器，保證深水井新鮮,，無泥沙,、雜質(zhì)等。出水管為口徑1-2.5英寸的尼龍管,，深水泵懸浮在深水井中井管,，距離井口約20米，取決于地下水動態(tài)水位的上升,。管壁四周用較粗的黃砂封條,，井口上方可封平，使地面恢復原貌,。本規(guī)范深井鉆井要求施工單位提供動力（三相）,、水、砂,、泥水排放通道,，鉆井時間一般為1-2天左右基本完成。

二：流量30-120噸左右,，深度一般開到80-150米左右,，鉆孔直徑600mm左右，下井壁管直徑360mm,，抽水功率7.5-36KW潛水多級深井泵,，井壁管規(guī)格為360mm×6mm×4000mm鋼混預制管，進水管外包有滲透過濾器,，出水管出水口直徑管材為2-4寸防腐鐵管,。深井泵放置在深井內(nèi)約40-70米處，根據(jù)地下動態(tài)水位上升的程度,，取水管四周充填V3.2mm規(guī)格的石英砂,，石英砂上方全部為用泥漿密封,，井口以上全部密封平整，使地面恢復原狀,。本規(guī)范深井鉆井施工單位必須提供電源（三相30KW可連續(xù)使用）,、排水及泥水排水通道，鉆井時間一般為2-7天左右,。

三,、淡水井鉆井包水質(zhì)一般要求比較嚴格，水質(zhì)指標成分基本超過飲用水標準,，流速在每小時10-100噸左右,，鉆井深度江浙滬一般需要在水下130米（上海需要在150米），放井壁管規(guī)格為360mm×6mm×4000mm鋼混預制油管,，出水管直徑為1.5-4英寸防腐鐵管,，深井泵放置在深井約40-80米處，視地下動態(tài)水位上升的程度而定,。透水管四周填滿V3.2mm規(guī)格的石英砂,，上層石英砂必須用粘性強、無雜質(zhì)的黃泥密封,，井口頂部可以密封平整恢復地面恢復到原來的形狀,。本規(guī)范深井鉆進過程中，施工單位必須提供電力（三相30KW可連續(xù)使用）,、水和黃泥（輸送至明井一側(cè)）,。鉆孔時間通常約為5-15天。

四：在巖石地下鉆深井,，這個深井的鉆探是否更高,，持續(xù)時間更長,，根據(jù)不同的地質(zhì)巖石結(jié)構(gòu)來協(xié)商鉆探,。

打深水井必須要用到地下水探測儀，地下水探測儀用于勘探尋找基巖水,、裂隙水,、巖溶水等，已知的探測地下水方法有間接找水法和直接找水法,。間接的探測地下水方法有天然電場法,、電法、磁法,、重力法等物探方法,。目前應用廣泛的簡介找水法為天然電場法

Python是一種面向?qū)ο笥兄a簡潔,、可讀性強特點的解釋型計算機程序設計語言。代碼簡潔是因為它把許多的復雜的操作封裝起來,，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節(jié),。另外Python這門語言強制用戶用縮進進行排版,，若不好好排版，則代碼編譯無法通過,，或者運行過程會出現(xiàn)錯誤,。

C語言

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

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

Java

Java通過面向作為靜態(tài)對象的編程語言的代表,，可以充分的實現(xiàn)面向的對象理論的編程語言，有簡單性,、功能強大,、分布式、健壯性,、安全性,、平臺獨立與可移植性,、多線程及動態(tài)性的特點,。

Java支持在網(wǎng)絡上應用，Java既支持各種層次的網(wǎng)絡連接,，又以Socket類支持可靠的流（stream）網(wǎng)絡連接,，它是分布式語言。所以用戶可以產(chǎn)生分布式的客戶機和服務器,。網(wǎng)絡變成軟件應用的分布運載工具,。Java程序只要編寫一次,，就可到處運行。

PHP

PHP是一種被廣泛應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于初學者來說極其簡單,，同時也給專業(yè)的程序員提供了各種高級的特性,，只需幾個小時就可以自己寫一些簡單的腳本。盡管 PHP 的開發(fā)是以服務端腳本為目的,，但事實上其功能遠不局限于此,。

GO

Go語言（又稱 Golang）是一種靜態(tài)強類型、編譯型語言,，是一個開源編程環(huán)境,，可以輕松構(gòu)建簡單、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,、應用,、運行、對象,、聲明,、測試和調(diào)試難度、復雜度,、學習程度,。 測試和調(diào)試難度不同：Python相對其他語言而言是非常簡單的語言，高度集成,，代碼量少,。Python中的測試和調(diào)試更容易；C中測試和調(diào)試更難,。 學習難度不同：Python：Python程序更易于學習,，編寫和閱讀；C語言：C程序語法比Python更難。

python 跟 java 一樣是強類型語言,，也就是說它不會根據(jù)環(huán)境變化自動改變數(shù)據(jù)類型,。python 是動態(tài)語言，而 java 是靜態(tài)語言,。也就是說 python 在編程時,，永遠不用給任何變量指定數(shù)據(jù)類型，而 java 寫程序時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模塊導入會執(zhí)行 代碼的內(nèi)容，而 java 不會,。python 與 java 的執(zhí)行方式還是蠻像的,，都是將源碼編譯成 byte code 然后交給相應的虛擬機去執(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使用非常嚴格的縮進強制執(zhí)行，使它比PHP更具可讀性,。

學習思路

認識編程

編程語言（programming language）又稱程序設計語言,，是一組用特定語言編寫的用于執(zhí)行特定任務的指令。主要用于開發(fā)桌面應用,、操作系統(tǒng),、網(wǎng)站、移動應用等,。

低級編程語言

它基于二進制數(shù) 0 和 1 工作,，處理器直接運行低級程序，不需要編譯器或解釋器,，因此用低級語言編寫的程序可以運行得非?？臁?/p>

低級語言進一步分為兩部分

機器語言

機器語言也稱為機器代碼或目標代碼,，更容易閱讀,，因為它通常以二進制或十六進制形式（基數(shù) 16）形式顯示。

它不需要翻譯器來轉(zhuǎn)換程序,，因為計算機直接理解機器語言程序,。

匯編語言

匯編語言是為特定處理器設計的，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)換為機器語言,。

中級編程語言

中級編程語言介于低級編程語言和高級編程語言之間。

它也被稱為中間程序語言和偽語言,。

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

例如：C,、C++

高級編程語言

高級編程語言 (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器語言（執(zhí)行程序）,。

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

編程實踐

學習編程語言的過程簡單描述為：過,、抄、仿,、改,、調(diào)、看,、練,、創(chuàng)、悟,。

過

基礎(chǔ)知識點不求深解,，語言什么樣的，適用場合,、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)試驗證自己想法,，繼續(xù)思考,，再次驗證。熟悉調(diào)試工具調(diào)試方法

看n遍

出錯或者遇到問題時,，將代碼從頭到尾看n遍直到快記住,，找出問題原因

練

2-5步三遍以上

創(chuàng)新

拿出一個沒有寫過的根據(jù)要求，一步一步寫出來,，寫不出來參考6

悟

主動找到寫代碼的感覺和成就感,，保持下去。

選擇大于努力,，只有切入一個適合自己的開發(fā)方向,，才能持續(xù)進步。關(guān)于開發(fā)方向，我有以下兩個選擇標準,。

興趣

學習編程是一個非?？菰锏倪^程，內(nèi)容多,，時間長,，成本高，即使報名了培訓班也學不會,，所以,，我們首先要選擇自己感興趣的一個開發(fā)方向，這樣不但能快速學習,，以后還能持續(xù)進步,。學習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,，別人告訴你這個想法不靠譜，你就放棄了,，這頂多是一時的雞血,。

學習方式

費曼學習法

在學完一個東西之后去給別人講明白，注意是講給別人聽,，當你寫成文章發(fā)表在網(wǎng)上的時候,，你自然會去用更通俗的語言，更清晰的邏輯去講述這個事物背后的邏輯,。這個過程是對自己學習的一個檢驗,，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,，很有可能你會傾向于去照抄,，或是不完全照抄，以“提綱”或是“知識點”的形式抄在本子上,。說句實話,，照抄的筆記真的沒用，因為現(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,，一個好的個人技術(shù)博客，會給你的簡歷加分很多,，而一個厚厚的筆記本,，沒有人會管你記了什么。

做好筆記

大多數(shù)人沒有過目不忘的神技,，學了也不一定馬上掌握,，需要過后花時間慢慢領(lǐng)悟,，而且還有忘掉的風險,，所以對于重要的知識點都要做好筆記。編程的過程中總會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，編程過程中的錯誤,、異常,，軟件更新問題等等。面對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，而是以防下次出現(xiàn),。

多看官方文檔

外文資料互聯(lián)網(wǎng)是一個更新迭代很快的行業(yè),，所有編程語言都會不斷的更新新功能和修復舊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。

進入行業(yè)圈子

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

動手做項目

學習編程的最終目的就是用所學的做出具有一定功能的項目,，而做項目又是最好的學習和鞏固知識的方式,。如果前期能力不足就先做一些簡單的功能模塊，一步一步慢慢來,，不要一開始就要實現(xiàn)各種酷炫炸天功能,，遇到不會的就在網(wǎng)上查， 現(xiàn)在互聯(lián)網(wǎng)這么發(fā)達,，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時間,，二是自己技術(shù)能力不足還可能留下不少坑,。

學習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：運行下載的安裝程序,，注意勾選“Add Python3.7 to PATH”,然后選擇個性化安裝,，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：高級選項,，需要的可以修改安裝目錄,，通常沒有需要修改的，直接點“Install”,。

第五步：等待程序自動安裝完成,。

第六步：出現(xiàn)如下界面，說明安裝已完成,。

第七步：驗證方法,，Windows+R 鍵打開“運行”窗口，輸入cmd運行,，進入命令提示窗口,，再輸入python，進入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,。

運行環(huán)境

Hello World!

命令行

在Linux命令行輸入：$python

將直接進入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是一個常用函數(shù),，其功能就是輸出括號中得字符串。

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

小程序

另一個使用Python的方法,，是寫一個Python程序,。用文本編輯器寫一個.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自動決定的。

>>>print(a)

>>>print(type(a))

那么會有如下輸出：

10

這里,，我們學到一個內(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存儲不同的數(shù)據(jù),，你不需要刪除原有變量就可以直接賦值,。

>>>a = 1.3

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

會有如下輸出

1.3

序列

sequence（序列）是一組有順序的元素的集合,，（嚴格的說,，是對象的集合，但鑒于我們還沒有引入“對象”概念,，暫時說元素）序列可以包含一個或多個元素,，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序列，以及我們以后要介紹的其他對象,。

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tuple

>>>s2 = [True, 5, 'smile'] # s2是一個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的各個元素不可再變更,，而list的各個元素可以再變更。

一個序列作為另一個序列的元素

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

空序列

>>>s4 = []
