1. 308kc m玄机资料，如何学编程？

编程是编定程序的中文简称，就是让计算机代码解决某个问题，对某个计算体系规定一定的运算方式，使计算体系按照该计算方式运行，并最终得到相应结果的过程。编程能提高逻辑思维能力，加强计算能力。

编程语言

Python

Python是一种面向对象有着代码简洁、可读性强特点的解释型计算机程序设计语言。代码简洁是因为它把许多的复杂的操作封装起来，将C语言中麻烦的指针和内存管理对开发者隐藏起来，使得在开发过程中，无须在意这部分的细节。另外Python这门语言强制用户用缩进进行排版，若不好好排版，则代码编译无法通过，或者运行过程会出现错误。

C语言

C语言是一门面向过程的、抽象化的广泛应用于底层开发的通用程序设计语言，能以简易的方式编译和处理低级存储器。C语言既具有高级语言的特点，又具有汇编语言的特点，是仅产生少量机器语言以及不需要任何运行环境支持便能运行的高效率程序设计语言。

是有简洁的语言、具有结构化的控制语句、丰富的数据类型、丰富的运算符、可对物理地址进行直接操作、代码具有较好的可移植性、可生成高质量、目标代码执行效率高的程序。

Java

Java通过面向作为静态对象的编程语言的代表，可以充分的实现面向的对象理论的编程语言，有简单性、功能强大、分布式、健壮性、安全性、平台独立与可移植性、多线程及动态性的特点。

Java支持在网络上应用，Java既支持各种层次的网络连接，又以Socket类支持可靠的流（stream）网络连接，它是分布式语言。所以用户可以产生分布式的客户机和服务器。网络变成软件应用的分布运载工具。Java程序只要编写一次，就可到处运行。

PHP

PHP是一种被广泛应用的开放源代码的多用途脚本语言，它可嵌入到 HTML中，尤其适合 web 开发。

使用 PHP 的最大的好处是它对于初学者来说极其简单，同时也给专业的程序员提供了各种高级的特性，只需几个小时就可以自己写一些简单的脚本。尽管 PHP 的开发是以服务端脚本为目的，但事实上其功能远不局限于此。

GO

Go语言（又称 Golang）是一种静态强类型、编译型语言，是一个开源编程环境，可以轻松构建简单、可靠和高效的软件。Go 语言语法与 C 相近，但功能上有：内存安全，GC（垃圾回收），结构形态及 CSP-style 并发计算。Go 内嵌了关联数组（也称为哈希表（Hashes）或字典（Dictionaries）），就像字符串类型一样。

对比

python和c语言的区别主要体现在：语言类型、内存管理、速度、应用、运行、对象、声明、测试和调试难度、复杂度、学习程度。 测试和调试难度不同：Python相对其他语言而言是非常简单的语言，高度集成，代码量少。Python中的测试和调试更容易；C中测试和调试更难。 学习难度不同：Python：Python程序更易于学习，编写和阅读；C语言：C程序语法比Python更难。

python 跟 java 一样是强类型语言，也就是说它不会根据环境变化自动改变数据类型。python 是动态语言，而 java 是静态语言。也就是说 python 在编程时，永远不用给任何变量指定数据类型，而 java 写程序时必须声明所有变量的数据类型。

python 的模块类似于 java 的 class，不过python模块导入会执行 代码的内容，而 java 不会。python 与 java 的执行方式还是蛮像的，都是将源码编译成 byte code 然后交给相应的虚拟机去执行。

Python的框架数量较少，而PHP中成熟的框架比较多；PHP是面向web的语言，而Python是多用途语言，也可以用于web开发；Python使用非常严格的缩进强制执行，使它比PHP更具可读性。

学习思路

认识编程

编程语言（programming language）又称程序设计语言，是一组用特定语言编写的用于执行特定任务的指令。主要用于开发桌面应用、操作系统、网站、移动应用等。

低级编程语言

它基于二进制数 0 和 1 工作，处理器直接运行低级程序，不需要编译器或解释器，因此用低级语言编写的程序可以运行得非常快。

低级语言进一步分为两部分

机器语言

机器语言也称为机器代码或目标代码，更容易阅读，因为它通常以二进制或十六进制形式（基数 16）形式显示。

它不需要翻译器来转换程序，因为计算机直接理解机器语言程序。

汇编语言

汇编语言是为特定处理器设计的，它以象征性和人类可理解的形式表示一组指令。它使用汇编程序将汇编语言转换为机器语言。

中级编程语言

中级编程语言介于低级编程语言和高级编程语言之间。

它也被称为中间程序语言和伪语言。

中级编程语言的优点是支持高级编程的特性，是一种用户友好的语言，与机器语言和人类语言密切相关。

例如：C、C++

高级编程语言

高级编程语言 (HLL) 旨在开发用户友好的软件程序和网站。

这种编程语言需要编译器或解释器将程序翻译成机器语言（执行程序）。

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

编程实践

学习编程语言的过程简单描述为：过、抄、仿、改、调、看、练、创、悟。

过

基础知识点不求深解，语言什么样的，适用场合、基本语法格式

抄代码

从书上抄、例子中抄、边抄边想边想边回忆语法

模仿改

仿照给出的代码写出自己的代码

勤调试

不断调试验证自己想法，继续思考，再次验证。熟悉调试工具调试方法

看n遍

出错或者遇到问题时，将代码从头到尾看n遍直到快记住，找出问题原因

练

2-5步三遍以上

创新

拿出一个没有写过的根据要求，一步一步写出来，写不出来参考6

悟

主动找到写代码的感觉和成就感，保持下去。

选择大于努力，只有切入一个适合自己的开发方向，才能持续进步。关于开发方向，我有以下两个选择标准。

兴趣

学习编程是一个非常枯燥的过程，内容多，时间长，成本高，即使报名了培训班也学不会，所以，我们首先要选择自己感兴趣的一个开发方向，这样不但能快速学习，以后还能持续进步。学习编程的过程是比较艰苦的，没有兴趣很难硬抗下来，此处的兴趣，是指别人无法撼动的热爱，是工作之余让你放松的事情。如果你只是有过某种想法，别人告诉你这个想法不靠谱，你就放弃了，这顶多是一时的鸡血。

学习方式

费曼学习法

在学完一个东西之后去给别人讲明白，注意是讲给别人听，当你写成文章发表在网上的时候，你自然会去用更通俗的语言，更清晰的逻辑去讲述这个事物背后的逻辑。这个过程是对自己学习的一个检验，也是加深映像整理思路的重要过程。

那么如果你是去记笔记的话，很有可能你会倾向于去照抄，或是不完全照抄，以“提纲”或是“知识点”的形式抄在本子上。说句实话，照抄的笔记真的没用，因为现在搜索引擎的能力已经可以让你把大多数东西快速找到，你为什么还要照抄到笔记本上呢？

从功利的角度考虑，技术文章的写作，别人可以直接访问，也可以逐渐累积你的影响力，一个好的个人技术博客，会给你的简历加分很多，而一个厚厚的笔记本，没有人会管你记了什么。

做好笔记

大多数人没有过目不忘的神技，学了也不一定马上掌握，需要过后花时间慢慢领悟，而且还有忘掉的风险，所以对于重要的知识点都要做好笔记。编程的过程中总会遇到各种各样的问题，比如编程环境的配置，常用的快捷键，编程过程中的错误、异常，软件更新问题等等。面对这些问题都是如何解决的，一定要记录下来，一是增加自己解决问题的经验，而是以防下次出现。

多看官方文档

外文资料互联网是一个更新迭代很快的行业，所有编程语言都会不断的更新新功能和修复旧Bug，网上查的资料很有可能是旧的解决方案，现在已经不适用了。所以最好最快的方法就是查看官方文档。

进入行业圈子

只有进入行业圈子与其他人交流，你才了解最新的行业动态，才知道自己需要更新哪些技能。

动手做项目

学习编程的最终目的就是用所学的做出具有一定功能的项目，而做项目又是最好的学习和巩固知识的方式。如果前期能力不足就先做一些简单的功能模块，一步一步慢慢来，不要一开始就要实现各种酷炫炸天功能，遇到不会的就在网上查， 现在互联网这么发达，获取资源也及其方便。而且开发前也最好在网上查一下有没有已经成型的框架或模板，什么都自己做一是很耗费时间，二是自己技术能力不足还可能留下不少坑。

学习Python

安装编程环境

第一步：访问Python官网，获取最新安装程序。

第二步：运行下载的安装程序，注意勾选“Add Python3.7 to PATH”,然后选择个性化安装，即“Customize installation”。

第三步：确保“pip”被勾选上，之后安装各种库需要用到pip。

第四步：高级选项，需要的可以修改安装目录，通常没有需要修改的，直接点“Install”。

第五步：等待程序自动安装完成。

第六步：出现如下界面，说明安装已完成。

第七步：验证方法，Windows+R 键打开“运行”窗口，输入cmd运行，进入命令提示窗口，再输入python，进入Python的命令模式，输入 print("Hello")，结果输出了 Hello，如下图所示，确定开发环境已安装完成。

运行环境

Hello World!

命令行

在Linux命令行输入：$python

将直接进入python。然后在命令行提示符>>>后面输入：>>>print('Hello World!')

可以看到，随后在屏幕上输出:

Hello World!

print是一个常用函数，其功能就是输出括号中得字符串。

（在Python 2.x中，print还可以是一个关键字，可写成print 'Hello World!'，但这在3.x中行不通 ）

小程序

另一个使用Python的方法，是写一个Python程序。用文本编辑器写一个.py结尾的文件，比如说hello.py

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

退出文本编辑器，然后在命令行输入：$python hello.py

来运行hello.py。可以看到Python随后输出Hello World!

脚本

我们还可以把Python程序hello.py改成一个可执行的脚本，直接执行：#!/usr/bin/env python

print('Hello World!')

需要修改上面程序的权限为可执行：chmod 755 hello.py

然后再命令行中，输入./hello.py

就可以直接运行了。

基本数据类型

变量不声明

Python的变量不需要声明，你可以直接输入：>>>a = 10

那么你的内存里就有了一个变量a， 它的值是10，它的类型是integer (整数)。 在此之前你不需要做什么特别的声明，而数据类型是Python自动决定的。

>>>print(a)

>>>print(type(a))

那么会有如下输出：

10

这里，我们学到一个内置函数type()，用以查询变量的类型。

回收变量名

如果你想让a存储不同的数据，你不需要删除原有变量就可以直接赋值。

>>>a = 1.3

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

会有如下输出

1.3

序列

sequence（序列）是一组有顺序的元素的集合，（严格的说，是对象的集合，但鉴于我们还没有引入“对象”概念，暂时说元素）序列可以包含一个或多个元素，也可以没有任何元素。

我们之前所说的基本数据类型，都可以作为序列的元素。元素还可以是另一个序列，以及我们以后要介绍的其他对象。

序列有两种：tuple（定值表； 也有翻译为元组） 和 list (表)

>>>s1 = (2, 1.3, 'love', 5.6, 9, 12, False) # s1是一个tuple

>>>s2 = [True, 5, 'smile'] # s2是一个list

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

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

tuple和list的主要区别在于，一旦建立，tuple的各个元素不可再变更，而list的各个元素可以再变更。

一个序列作为另一个序列的元素

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

空序列

>>>s4 = []

2. ps修图技巧？

PS一般指Adobe Photoshop，是由Adobe Systems开发和发行的图像处理软件。修图也即修改图片，将图片进行一定的处理，修调，从而达到需要的效果。

了解界面

菜单栏

顶部区域是菜单栏，将Photoshop所有的操作分为九类，除了【帮助】选项，共九项菜单。如编辑、图像、图层、滤镜。

工具属性栏

蓝色部分称为工具属性栏，左侧工具栏中的每个工具选项都对应不同的工具属性(如下图)，所以选择不同的工具或选择不同的对象时出现的选项也不同。

工具栏

红色区域中的竖长条称为工具栏，也称为工具箱。对图像的修饰以及绘图等工具，都从这里调用。几乎每种工具都有相应的键盘快捷键。

浮动面板

PS的的右上方是浮动面板区域。浮动面板是Photoshop中非常重要的辅助工具，它为图形图像处理提供了各种各样的辅助功能。每个浮动面板都可以用鼠标进行拖拽随意放置符合你工作惯性的地方。

标题栏

标题栏显示的是对工作区命名。

状态栏

包含四个部分，分别为：图像显示比例、文件大小、浮动菜单按钮及工具提示栏。

图层工具栏

包含：图层关联、图层样式、蒙版、滤镜、图层组、图层、删除图层，这7大功能。

工作区

Photoshop可以同时打开多幅图像进行制作，图像之间还可以互相传送数据。在打开的图像间可通过菜单【窗口】底行的图像名称切换，也可以快捷键【CTRL+TAB】完成图像切换。

工作区灰色的区域称为工作区，用来显示制作中的图像。Photoshop可以同时打开多幅图像进行制作，图像之间还可以互相传送数据。在打开的图像间可通过菜单【窗口】底行的图像名称切换，也可以快捷键【CTRL+TAB】完成图像切换。

小窍门

具体每一个工具的名称，只要把鼠标移动到该工具上，旁边就会出现工具名称。

修图方法

使用多个图层

在工作中尽可能地使用多个图层，图层的作用，就是为了方便后期更改，否则Photoshop后期的修图和合成很难一次成型，为了让作品更完美，创作过程中会反复修改，因而最好在每一个关键的部分都新建一个图层。

图层透明度的修改，一般都是在图层上方有个透明度，拉下图层上放的透明度滑块就可以修改了，还有更快的方法，就是选择图层，按下键盘数值可以直接修改透明度，按下数值1就是修改10%的透明度，按下数值2就是修改20%的透明度，按下数值3就是修改30%的透明度，以此类推，可以快速改变图层透明度。

多使用蒙版

能想到删除和擦除这两个动作的地方，都可以用蒙版来代替。

删除和擦除是一种有破坏性的编辑，它们对于图层内容的伤害是不可逆的，而蒙版只是暂时隐藏选中的图像部分。好处在于，可以随时地对该部分图像进行继续隐藏或恢复等操作，并且无论操作多少遍，都对原图没有任何的破坏，蒙版是一种无损的编辑方式。

蒙版的使用方式

首先第一步打开素材，点击快速蒙版按钮。

使用画笔工具，大致选中照片中人像。

再次点击快速蒙版，退出快速蒙版模式，按住Ctrl+shift+I键进行反选。

在顶部菜单栏中执行“选择”-“选择并遮住”（老版本PS叫做调整边缘）。

接下来我们把透明度设为100，边缘检测半径设为60，移动边缘设置为15，选中净化颜色数值设置为57。

接下来选中调整边缘画笔工具，涂抹带有背景图层的位置，设置数值和效果。

多利用智能对象和智能滤镜

在对图像进行放大、缩小、扭曲、旋转和变形等操作时，都会有或多或少损失一部分画质，而将普通图层转化为智能对象后，再进行上述操作时，将保留图像一切的原始特性，不会对图像的原始画质造成任何的破坏，因而，智能对象也是一种无损的编辑方式。

右击图层，跳出来的窗口之后，选择“转换为智能对象”。

一些滤镜没有预览功能，只能设置一次参数看一次效果，如果不满意就得从头开始，使用智能滤镜后就可以很方便地修改滤镜的参数，不透明度和混合模式等。

多利用调整图层

当需要对图层的色阶、亮度，曲线和颜色等做出调整时，如果直接在原图上修改，那么后期将很难再进行调整，调整图层是一个独立图层调整，图层是一个独立图层，在这个图层上可以反复进行多次的无损调整，最终效果不满意，还可以直接删除这个调整图层，然后重新添加一个调整图层，就可以继续对原图层进行调整，这个过程对原图层是没有任何影响的。

多使用快捷键

使用快捷键，是最能提升工作效率的操作，这就好比设置的特殊电话号码，按“1”直接就是打给父母，按“2”就是直接打给妻子。

快捷键位置：

点击打开之后，界面如下：

抠图技巧

1、钢笔工具抠图

钢笔工具适用于外形复杂、不连续、色差不大的图，加工精度高、纯手工放大边界点来抠图，先将需要抠图的素材拖到ps中。

选择“钢笔工具”。

接着在需要抠图的地方描点。

将需要抠出来的部分都圈住后点击鼠标右键，选择“建立选区”。

调整羽化半径，根据描点距离图片的距离选择，勾选“消除锯齿”后点击“确定”。

然后建立好选区，可以利用快捷键“Ctrl+C”复制选区的图层。

在一个空白图层利用快捷键“Ctrl+V”粘贴即可完成抠图。

2、魔术棒抠图

魔术棒抠图适用于图像和背景色色差明显，背景单一，图像边界清晰的素材，首先将图片素材利用ps打开

接着点击“魔棒工具”

然后调整容差值为“32”，勾选“连续”和“消除锯齿”

然后利用魔棒工具点击图片的背景区，选择一个区域后点击键盘上的删除键

把背景全部删除后即可完成抠图

3、色彩范围抠图

色彩范围抠图适用于背意景色单一，图像分明、背景无色彩的素材。首先利用Ps打开图片素材

接着点击“选择”选项卡

然后在弹出的选项中选择“色彩范围”

然后用颜色吸管拾取背景色

接着勾选“反相”并点击“确定”

然后会建立一个选区

最后利用快捷键“Ctrl+J”复制一层图层即可完成抠图

4、磁性索套工具抠图

磁性套索抠图适用于图像边界清晰，磁性索套会自动识别并黏附在图像边界上，如果边界模糊处放大了再放置这样就更精确，首先利用ps打开图片素材

然后选择“磁性套索工具”

接着将鼠标移到图像边界处，然后磁性套索工具自动识别并黏附在图像边界上

等磁性套索工具闭合后就将整个图像都选中了

然后利用快捷键“Ctrl+J”复制一层图层即可完成抠图

5、羽化法抠图

羽化法抠图适用于边界清楚的素材，首先利用ps打开图片素材

然后选择“套索工具”

接着利用套索工具将图像选中

然后点击鼠标右键，选择“羽化”

根据套索与图像的距离调整羽化半径，距离较近就调小点，如调整羽化半径为“5”后点击“确定”

然后就将图像抠出来了，但是周围有不需要的部分，可以利用橡皮擦工具擦去

点击选择“橡皮擦工具”

将周围多余的部分擦去即可完成抠图

6、蒙板抠图

蒙板抠图快速并直观适用范围广，首先利用ps打开图片素材

然后利用快捷键“Ctrl+J”复制一层图层

然后选择“图层1”并点击“添加图层蒙版”

接着将前景色调为黑色，背景色调为白色

调好后选择“画笔工具”

调整画笔工具的颜色为黑色，并选择图层蒙版

接着利用画笔工具将背景擦去即可完成抠图，如果不小心将图像擦掉了，可以交换前景色和背景色在擦除即可还原

7、通道抠图

通道抠图适用于色差不大，外形复杂的图形，像毛发及树枝等。首先利用ps打开图片素材

然后利用快捷键“Ctrl+j”复制一层图层

接着点击“通道”

选择并复制一个图像清楚的通道，如“蓝色”

然后点击“图像”选项卡

选择“调整”下的“色阶”

然后调整色阶以增强图像对比度，调整好后点击“确定”

接着选择“快速选择工具”

将图像选中，边界处可以放大在选择

选择好后点击“编辑”选项卡

在弹出来的选项中选择“填充”

将图像填充为背景色即为黑色，点击“确定”

然后选择“图像”选项卡

选择调整下的“反相”将背景设置为白色

接着利用快捷键“Ctrl+J”复制一层图层

接着将图层1和背景的“小眼睛”关闭即可查看抠出来的图像

8、反向抠图

找到图片，点击打开。

点击使用魔棒工具。

点击外部空白区域。

点击右键，点击“选择反向”。

再点击右键，选择通过拷贝（剪切）的图层。

删除背景图层。

如图，抠图完成。

去水印技巧

1、使用仿制图章工具去除

使用仿制图章工具去除文字这是比较常用的方法，具体的操作是，选取仿制图章工具，按住Alt键，在无文字区域点击相似的色彩名图案采样，然后在文字区域拖动鼠标复制以覆盖文字。

要注意的是，采样点即为复制的起始点。选择不同的笔刷直径会影响绘制的范围，而不同的笔刷硬度会影响绘制区域的边缘融合效果。

2、使用修补工具去除文字

如果图片的背景色彩或图案比较一致，使用修补工具就比较方便。

具体操作是：选取修补工具，在公共栏中选择修补项为“源”，关闭“透明”选项。然后用修补工具框选文字，拖动到无文字区域中色彩或图案相似的位置，松开鼠标就完成复制。

修补工具具有自动匹配颜色的功能，复制的效果与周围的色彩较为融合，这是仿制图章工具所不具备的。

3、使用修复画笔工具去除文字

操作的方法与仿制图章工具相似。按住Alt键，在无文字区域点击相似的色彩或图案采样，然后在文字区域拖动鼠标复制以覆盖文字，只是修复画笔工具与修补工具一样，也具有自动匹配颜色的功能，可根据需要进行选用。

4、应用消失点滤镜法

对于一些透视效果较强的画面(如地板)，可以应用“消失点”滤镜进行处理。

操作方法是，框选要处理的文字区域，(防止选区以外的部分也被覆盖)执行菜单命令：滤镜——消失点，进入消失点滤镜编辑界面。

1)选取左边工具栏中的创建面板工具，由地板砖缝交汇处开始，沿着缝隙，依次点四个点，连成一个有透视效果的矩形。然后拖动其边线向右方及下方扩展，令面板完全覆盖文字。

2)选取左边工具栏中的图章工具，按住Alt键点击选取源图像点，待颜色变化后，在文字区域拖动便完成复制。

人像磨皮

首先通过快捷键Ctrl+O键打开一张人物图片，然后通过Ctrl+J键将图片复制一层，在滤镜菜单下找到“Neural Filters...”单击打开。

先开启“皮肤平滑度”按钮，再调整“模糊、平滑度”数值，最后点击确定，以智能对象方式输出。

ps2021新增的平滑度滤镜可以一键识别人物脸部，并进行磨皮，还可以通过智能滤镜进行修改，效果与美颜相机类似。

图片上色技巧

首先我们用ps打开图片。

然后新建一个图层。

将图层混合模式设置为颜色。

接着选择画笔前景色。

然后在图层上使用画笔上色即可。
