Github 使用git将项目上传到github（最简单方法）

2021-03-16T07:41:45+00:00

首先你需要一个github账号，所有还没有的话先去注册吧！https://github.com/我们使用git需要先安装git工具，这里给出下载地址，下载后一路直接安装即可：https://git-for-windows.github.io/1.进入Github首页，点击New repository新建一个项目2.填写相应信息后点击create即可 Repository name: 仓库名称Description(可选): 仓库描述介绍Public, Private : 仓库权限（公开共享，私有或指定合作者）Initialize this repository with a README: 添加一个README.mdgitignore: 不需要进行版本管理的仓库类型，对应生成文件.gitignorelicense: 证书类型，对应生成文件LICENSE3.点击Clone or dowload会出现一个地址，copy这个地址备用。4.接下来就到本地操作了，首先右键你的项目，如果你之前安装git成功的话，右键会出现两个新选项，分别为Git Gui Here,Git Bash Here,这里我们选择Git Bash Here，进入如下界面，Test_Bluetooth即为我的项目名。5.接下来输入如下代码（关键步骤），把github上面的仓库克隆到本地git clone https://github.com/CKTim/BlueTooth.git（https://github.com/CKTim/BlueTooth.git替换成你之前复制的地址） 6.这个步骤以后你的本地项目文件夹下面就会多出个文件夹，该文件夹名即为你github上面的项目名，如图我多出了个Test文件夹，我们把本地项目文件夹下的所有文件（除了新多出的那个文件夹不用），其余都复制到那个新多出的文件夹下，7.接着继续输入命令 cd Test，进入Test文件夹8.接下来依次输入以下代码即可完成其他剩余操作：git add . （注：别忘记后面的.，此操作是把Test文件夹下面的文件都添加进来）git commit -m "提交信息" （注：“提交信息”里面换成你需要，如“first commit”）git push -u origin master （注：此操作目的是把本地仓库push到github上面，此步骤需要你输入帐号和密码）

True >spam.endswith('Hello') False10.join()和split()的使用方法join()使列表通过某一个字符分开变为字符串例子：spam = ['my', 'name', 'is', 'Eric'] k =' '.join(spam) print(k)输出的结果为my name is Ericsplit()使字符串通过某一字符分开变为列表例子：spam = 'my name is Eric' j =spam.split() print(j)输出的结果为['my', 'name', 'is', 'Eric']10.rjust()&ljust()¢er()对齐的使用spam = 'my name is Eric' k = spam.rjust(30) print('输出k的值（右对齐30个字符）：', k) j = spam.ljust(30) print('输出j的值（左对齐30个字符）：', j) i = spam.center(30) print('输出i的值（居中对齐30个字符）：',i) k = spam.rjust(30, '#') print('输出k的值（右对齐30个字符）：', k) j = spam.ljust(30, '*') print('输出j的值（左对齐30个字符）：', j) i = spam.center(30, '-') print('输出i的值（居中对齐30个字符）：',i)11.strip()&rstrip()&lstrip()去除空格使用spam = ' Hello World!
