                       Python入门篇-pyenv安装及应用

                                               作者:尹正杰

    一.推荐Python相关书籍

    1>.《Python Cookbook》

    2>.《Learn Python The Hard Way》

    3>.《Google's Python Class》

    4>. 《简明Python教程》

     

    二.Python创始人介绍

     

    1>.荷兰人Guido van Rossum,2005年加入Google,2013年加入Dropbox;

    2>.1989年,创立Python语言,1991年初发布第一个公开发行版本;

    3>.他是英国BBC喜剧《Monty Python's Flying Circus》的忠实粉丝;

    4>.Python哲学(如下图所示,在python解释器中输入“import this”,就可以看到python哲学啦~)

     

    三.Python版本说明

    1>.Python版本

    Python2.x发展到2.7版本
        Python官网对2.x版本进行倒计时的网站:https://pythonclock.org/          
    
    python3.x发展到3.7版本
        Python官网对3.x版本始自2008年,3.5版本发布于2015年(如果你用Python的话建议选择大于或等于3.5级以上版本)
    
    
    不要迷信版本,学会一个版本,好好学会一门语言,其他都不是问题。

    2>.2.x和3.x的区别 

    1>.语句函数化,例如print(100,300),即打印出:“100 300”,但是2.x版本中意思是print语句打印元组,3.x中意思是函数的2个参数。
    
    
    2>.整除,例如“1/2”和“1//2”,3.x版本中“/”为自然除。
    
    
    3>.3.x中raw_input重命名为input,不再使用raw_input。

    4>.round函数,在3.x中i.5的取整变为距离最近的偶数。

    5>.字符串统一使用Unicode。

    6>.异常的捕获,抛出的语法改变。

    四.开发环境-Pyenv安装

    1>.Pyenv概述

    Pyenv是Python多版本管理工具(在也不怕升级python导致yum不可用啦~)
       1>.支持管理Python解释器;
       2>.支持管理Python版本;
       3>.支持管理Python的虚拟环境;
    
    官方网址:https://github.com/pyenv/pyenv

    2>.安装Git工具

    3>.使用pyenv查看当前版本

    [python@node101.yinzhengjie.org.cn ~]$ python -V            #这是我们在Linux操作系统身上使用python命令查看Python版本。是默认CentOS7.6默认安装的版本。
    Python 2.7.5                                  
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv version          #我们使用pyenv命令查看当前Python版本,它告诉我们说是当前版本为系统版本。
    system (set by /home/python/.pyenv/version)
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv versions          #查看当前环境所有的Python版本,因为我们到目前为止除了系统版本外还没有安装任何Python版本!因此我们只能看到系统版本版本哟~想看到其他版本咱们自行安装即可!
    * system (set by /home/python/.pyenv/version)
    [python@node101.yinzhengjie.org.cn ~]$

    4>.在线安装指定python版本(不推荐使用,因为在线安装带宽存在不稳定因素)

    [python@node101.yinzhengjie.org.cn ~]$ pyenv install 3.6.6 -v
    /tmp/python-build.20190510195824.14876 ~

    [python@node101.yinzhengjie.org.cn ~]$ pyenv install 3.6.6 -v        #这样的安装方式较慢,为了提速,可以选用cache方法

    5>.使用缓存方式安装python版本

    [python@node101.yinzhengjie.org.cn ~]$ ll .pyenv/

    六.Pyenv的基本使用

    1>.使用global参数切换Python版本(执行后立刻全局生效,即当前终端和所有当前用户的终端都会生效,不推荐使用!)

    [python@node101.yinzhengjie.org.cn ~]$ pyenv versions
    * system (set by /home/python/.pyenv/version)
      3.6.6
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv global 3.6.6
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv versions
      system
    * 3.6.6 (set by /home/python/.pyenv/version)
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv global 3.6.6
    [python@node101.yinzhengjie.org.cn ~]$ pyenv versions
      system
    * 3.6.6 (set by /home/python/.pyenv/version)
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv global system
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv versions
    * system (set by /home/python/.pyenv/version)
      3.6.6
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv global system

    2>.使用global参数切换Python版本(执行后立刻对当前终端生效,并不影响其他终端,你可以理解为临时性的,下次连接后恢复默认配置,用处不大)

    [python@node101.yinzhengjie.org.cn ~]$ pyenv version
    system (set by /home/python/.python-version)
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv shell 3.6.6
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv version
    3.6.6 (set by PYENV_VERSION environment variable)
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv shell 3.6.6

    3>.使用local参数切换Python版本(执行后立刻对当前目录及其子目录生效,强烈推荐使用,在生产环境使用它是再适合不过啦~)

    [python@node101.yinzhengjie.org.cn ~]$ ll
    total 0
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ mkdir devops/project -pv
    mkdir: created directory ‘devops’
    mkdir: created directory ‘devops/project’
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ cd devops/project/
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ pyenv local 3.6.6
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ pyenv version
    3.6.6 (set by /home/python/devops/project/.python-version)
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ python -V
    Python 3.6.6
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ pyenv local 3.6.6          #我们在当前目录执行Python版本环境
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ ll
    total 0
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ mkdir cmdb
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project]$ cd cmdb/
    [python@node101.yinzhengjie.org.cn ~/devops/project/cmdb]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project/cmdb]$ python -V
    Python 3.6.6
    [python@node101.yinzhengjie.org.cn ~/devops/project/cmdb]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project/cmdb]$ pyenv version
    3.6.6 (set by /home/python/devops/project/.python-version)
    [python@node101.yinzhengjie.org.cn ~/devops/project/cmdb]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project/cmdb]$ 
    [python@node101.yinzhengjie.org.cn ~/devops/project/cmdb]$ pyenv version          #发现使用local参数指定的Python环境及其子目录也是生效的!(需要注意的是,上一级目录和兄弟目录并不生效!)

    4>.更新pyenv版本(更新的目的是为了获得最新Python版本支持)

    [python@node101.yinzhengjie.org.cn ~]$ pyenv update
    Updating /home/python/.pyenv...
    From https://github.com/pyenv/pyenv
     * branch            master     -> FETCH_HEAD

    Already up-to-date.
    [python@node101.yinzhengjie.org.cn ~]$ 
    [python@node101.yinzhengjie.org.cn ~]$ pyenv update

    七.Virtualenv虚拟环境设置(主要应用于多人开发,方便实现包的管理等)

    1>.为什么要使用虚拟环境

       因为刚才使用的Python环境都是一个公共的空间,如果多个项目使用不同Python版本开发,或者使用不同的Python版本部署运行,或者使用同样的版本开发的但不同项目使用了不同版本的库等等。这些问题都会带来冲突,最后的解决办法就是每一个独立运行自己的“独立小环境”中。

    2>. 我们使用在线方式安装一下Python 3.7.1版本(需要注意的是,Python3.7以上版本需要安装“libffi-devel”软件包)

    [python@node101.yinzhengjie.org.cn ~]$ pyenv install 3.7.1 -v
    /tmp/python-build.20190510214733.69816 ~

    The Jupyter HTML Notebook.
    
    This launches a Tornado based HTML Notebook Server that serves up an
    HTML5/Javascript Notebook client.
    
    Subcommands
    -----------
    
    Subcommands are launched as `jupyter-notebook cmd [args]`. For information on
    using subcommand 'cmd', do: `jupyter-notebook cmd -h`.
    
    list
        List currently running notebook servers.
    stop
        Stop currently running notebook server for a given port
    password
        Set a password for the notebook server.
    
    Options
    -------
    
    Arguments that take values are actually convenience aliases to full
    Configurables, whose aliases are listed on the help line. For more information
    on full configurables, see '--help-all'.
    
    --debug
        set log level to logging.DEBUG (maximize logging output)
    --generate-config
        generate default config file
    -y
        Answer yes to any questions instead of prompting.
    --no-browser
        Don't open the notebook in a browser after startup.
    --pylab
        DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
    --no-mathjax
        Disable MathJax
        
        MathJax is the javascript library Jupyter uses to render math/LaTeX. It is
        very large, so you may want to disable it if you have a slow internet
        connection, or for offline use of the notebook.
        
        When disabled, equations etc. will appear as their untransformed TeX source.
    --allow-root
        Allow the notebook to be run from root user.
    --script
        DEPRECATED, IGNORED
    --no-script
        DEPRECATED, IGNORED
    --log-level=<Enum> (Application.log_level)
        Default: 30
        Choices: (0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL')
        Set the log level by value or name.
    --config=<Unicode> (JupyterApp.config_file)
        Default: ''
        Full path of a config file.
    --ip=<Unicode> (NotebookApp.ip)
        Default: 'localhost'
        The IP address the notebook server will listen on.
    --port=<Int> (NotebookApp.port)
        Default: 8888
        The port the notebook server will listen on.
    --port-retries=<Int> (NotebookApp.port_retries)
        Default: 50
        The number of additional ports to try if the specified port is not
        available.
    --transport=<CaselessStrEnum> (KernelManager.transport)
        Default: 'tcp'
        Choices: ['tcp', 'ipc']
    --keyfile=<Unicode> (NotebookApp.keyfile)
        Default: ''
        The full path to a private key file for usage with SSL/TLS.
    --certfile=<Unicode> (NotebookApp.certfile)
        Default: ''
        The full path to an SSL/TLS certificate file.
    --client-ca=<Unicode> (NotebookApp.client_ca)
        Default: ''
        The full path to a certificate authority certificate for SSL/TLS client
        authentication.
    --notebook-dir=<Unicode> (NotebookApp.notebook_dir)
        Default: ''
        The directory to use for notebooks and kernels.
    --browser=<Unicode> (NotebookApp.browser)
        Default: ''
        Specify what command to use to invoke a web browser when opening the
        notebook. If not specified, the default browser will be determined by the
        `webbrowser` standard library module, which allows setting of the BROWSER
        environment variable to override it.
    --pylab=<Unicode> (NotebookApp.pylab)
        Default: 'disabled'
        DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
    
    To see all available configurables, use `--help-all`
    
    Examples
    --------
    
        jupyter notebook                       # start the notebook
        jupyter notebook --certfile=mycert.pem # use SSL/TLS certificate
