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

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 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 ~]$
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 ~]$
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]$ 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]$
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. Updating /home/python/.pyenv/plugins/pyenv-doctor... From https://github.com/pyenv/pyenv-doctor * branch master -> FETCH_HEAD Already up-to-date.

Updating /home/python/.pyenv/plugins/pyenv-virtualenv... From https://github.com/pyenv/pyenv-virtualenv * branch master -> FETCH_HEAD Already up-to-date. Updating /home/python/.pyenv/plugins/pyenv-which-ext... From https://github.com/pyenv/pyenv-which-ext * branch master -> FETCH_HEAD Already up-to-date. [python@node101.yinzhengjie.org.cn ~]$
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 ~ Downloading Python-3.7.1.tar.xz... -> https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz

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.
