1. Python安装
简述
Python开发的前置条件，按照安装步骤结束后，后期开发主要的应用有以下项：
- python3：运行Python代码的“解释器”，用于Python语言的运行。
- pip3：第三方库安装工具，用户依赖库的安装。
- venv：虚拟环境，用户项目隔离，避免项目间的冲突。
步骤
- 执行命令安装：brew install python。（我用的是mac，如果使用windows的同理，使用对应系统的包资源管理器安装即可）。
- 执行命令检查：python3 --version，出现版本号即为安装成功。执行python3 -c "print('hello, python')"，正确的测试结果如下：
- 后期创建项目时会用到虚拟环境创建，比如：
# 1. 进入你想创建的文件夹（没有就先建）
cd ~/Documents # 先到文稿目录
mkdir myproject # 新建项目文件夹
cd myproject # 进入它
# 2. 现在这里创建虚拟环境
python3 -m venv myenv
# 3. 激活
source myenv/bin/activate
//激活后你的终端提示符会变成 `(myenv) 你的电脑名:myproject$`，这就说明你已经 "在这个房间里" 了。之后就可以在这个虚拟环境中使用pip install 去安装自己的依赖，且不会影响到其他项目
# 4. 退出
deactivate
- 后期创建项目时会用到依赖库的安装，比如：
pip3 install requests # 1. 装网络请求库
python3 -c "import requests; print(requests.__version__)" # 2. 确认能用
python3 my_script.py # 3. 运行你的程序
2. Vsode安装
简述
选择VsCode作为自己的IDE，进行软件项目开发。
步骤
- 在终端输入命令：brew install --cask visual-studio-code，安装vscode，在vscode中的选择安装自己喜好的编码插件，如下：
2.运行初学者的第一行代码：`print("Hello, World!")`
Gitee仓库创建
简述
使用国内的gitee，创建自己的代码仓库。
步骤
- 用于软件项目的代码管理，使用很简单在此不进行赘述，可自行研究学习。
至此编写代码的前置条件均已具备，后续进行代码的编程学习。

1. Python installation
Brief description
The main applications for the development of post-production, in accordance with the prefix conditions for the development of Python, are as follows:
- Python3: "Interpreters" for running the Python code.
- pip3: Third-party library installation tool, user dependent on library installation.
- venv: virtual environment, isolation of user projects and avoidance of conflict between projects.
Steps
- Executing command installation: brew install python. (I'm using mac, if it's the same thing as windows, it's enough using the corresponding system's package resource manager).
- Executing order inspection: python3-version, version number is successful. Execute python3-c "print" with the correct test results as follows:
- post-production projects are created using virtual environments such as:
# 1. Enter the folder you want to create (do not build first)
cd ~/Documents
mkdir myproject# New Item File Jack.
Cd myproject
# 2. Create virtual environments here
python3 -m venv myenv
3. Activate
source myenv/bin/activate
Your terminal hint will become `(myenv) your computer name: Myproject$ ', which means you're already in this room. Then you can use the pip install in this virtual environment to install your dependence without affecting other projects.
# 4. Exit
deactivate
- post-production creates projects that can be used for the installation of dependent libraries, such as:
pip3 install requests #1. Library
# 2. Confirm that it works
Run your program
2. Vsode installation
Brief description
Select VsCode as its own IDE for software project development.
Steps
- Enter commands at the terminal: brew install -- cask visual-studio-code, install vscode, install their preferred encoding plugins in vscode, as follows:
2. Run the first line code for beginners: `print'
Gitee repository creation
Brief description
Create your own code warehouse, using the national gitee.
Steps
- Code management for software projects, which is simple to avoid repetition and can be self-researched.
The pre-conditions for code writing are in place and code programming is followed.
