Python入门篇-pyenv安装及应用
作者：尹正杰
版权声明：原创作品，谢绝转载！否则将追究法律责任。
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 ~]$

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 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

[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

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
jupyter notebook password # enter a password to protect the server
