图书馆座位预约脚本

掌握技术者。需慎独。抢座太耗精力，所以闲来无事，在服务器上搞了预约图书馆座位的脚本。

centOS下升级python版本，详细步骤

!注意我的目录是/usr/local/python3/
1、可利用linux自带下载工具wget下载，如下所示：（
笔者安装的是最小centos系统，所以使用编译命令前，必须安装wget服务，读者如果安装的是界面centos系统，或者使用过编译工具则可跳过安装wget，直接进行下边的编译步骤）
wget http://www.python.org/ftp/python/3.3.0/Python-3.3.0.tgz
2、下载完成后到下载目录下，解压
tar -xzvf Python-3.3.0.tgz
3、进入解压缩后的文件夹
cd Python-3.3.0　　
4、在编译前先在/usr/local建一个文件夹python3（作为python的安装路径，以免覆盖老的版本）
mkdir /usr/local/python3 （此处新建文件夹用mkdir，如果是新建文件则用touch）
　　
5、开始编译安装（
笔者安装的是最小centos系统，所以使用编译命令前，必须安装编译套件gcc，读者如果安装的是界面centos系统，或者使用过编译工具则可跳过安装gcc，直接进行下边的编译步骤）
./configure —prefix=/usr/local/python3
make
make install
6、此时没有覆盖老版本，再将原来/usr/bin/python链接改为别的名字（笔者保留了两个版本的，一个python，一个python3，所以第6步笔者略过，把第7步的链接后名字改为python3，读者可按正常步骤，实现的效果相同）
mv /usr/bin/python /usr/bin/python_old2
　　
7、再建立新版本python的链接
ln -s /usr/local/python3/bin/python3 /usr/bin/python
　　
8、这个时候输入
python -V
　
10、就会显示出python的新版本信息
[idolaoxu@localhost home]# python -V
Python 3.3.0
PS：如果不建立新安装路径python3，而是直接默认安装，则安装后的新python应该会覆盖linux下自带的老版本，也有可能不覆盖，具体看安装过程了，
这个大家可以自己试验下，当然如果还想保留原来的版本，那么这种方法最好不过了。
Install pip3 for python 3.x 要注意其实python3 文件夹-bin目录下已经有一个，pip3，pip3.6了！
过程当中出现python requests环境错误——使得我不得不 /…/pip3 uninstall requests 然后重新 /…/pip3 install requests
