credit view 操作 pack running reference spa collected win 一.windows下安裝python
1》windows上python後綴是.msi的,下載下來後,直接雙擊運行。會在c盤生成python.exe的文件,把python.exe的文件加入到windows環境變量中:我的電腦---屬性---高級---環境變量--編輯--添加“c:\python27”--確定 C:\Python27 C:\Python27\Scripts

2》在windows下安裝完python後,進入cmd,輸入python,也會進入python命令行
3》windows驗證python及退出
4》windows 退出python exit()
二.linux 下安裝python
1》yum源安裝
安裝pip命令,用pip安裝ipython(pip install python)
[[email protected] ~]# cd soft/
[[email protected] soft]# ls
epel-release-6-8.noarch.rpm
[[email protected] soft]# rpm -ivh epel-release-6-8.noarch.rpm
warning: epel-release-6-8.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEY

[[email protected] soft]# cd /etc/yum.repos.d/
[[email protected] yum.repos.d]# ls //yum目錄下生成epel epel-testing.repo
a bak CentOS-Base.repo epel.repo epel-testing.repo
[[email protected] yum.repos.d]# yum -y install python-pip
[[email protected] yum.repos.d]# pip install ipython //安裝ipython,會通過ipython的官網,下載當前最新的版本進行安裝,註意,linux中python的版本是2.6,當前最新的iptyon的版本是6.0,網站上說明使用於python3,所以,安裝後報錯
[[email protected] yum.repos.d]# pip install ipython==1.2.1 //指定ipython的版本進行安裝,

2》源碼安裝ipython
[[email protected] soft]# ls
51CTO下載-ipython-1.2.1.tar.gz
[[email protected] soft]# tar xf 51CTO下載-ipython-1.2.1.tar.gz
[[email protected] soft]# ls
51CTO下載-ipython-1.2.1.tar.gz redis-3.2.8.tar.gz
ipython-1.2.1 zabbix-2.0.12.tar.gz
mongodb-linux-x86_64-rhel62-3.2.7.tgz
[[email protected] soft]# cd ipython-1.2.1/
[[email protected] ipython-1.2.1]# ls
COPYING.txt examples PKG-INFO scripts setupegg.py setup.py
docs IPython README.rst setupbase.py setupext
[[email protected] ipython-1.2.1]# python setup.py install //python執行setup腳本,就可以用ipython補全了
三.配置不同操作系統的環境變量
1》配置windows 系統環境變量
win10 操作系統環境變量在一下路徑進行添加可執行程序:
我的電腦---屬性---高級---環境變量--編輯--添加
2》linux系統環境變量配置
例如要添加php命令,php安裝在 /usr/local/webserver/php 下。永久有效添加php命令:
[[email protected] ~]# vim /etc/profile //在文件末尾添加如下兩行內容
.........................
........................
#php
export PATH=/usr/local/webserver/php/bin:$PATH
[[email protected] ~]# source /etc/profile //是環境變量生效
四.python 從 "hello world"開始
#/usr/bin/python
#coding=utf-8
#@Time :2017/10/16 8:59
#@Auther :liuzhenchuan
#@File :python 從 hello world 開始.py
a = ‘hell world‘
print a
print ‘###‘*20
name = raw_input(‘please input you name: ‘)
print ‘hell world %s‘ % name
>>> hell world
###############################################
please input you name: liuzhenchuan
hell world liuzhenchuan
