					<description><![CDATA[PEMDAS 这个简称来辅助记忆，它的意思是“括号（Parentheses）、指数（Exponents）、乘（Multiplication）、除（Division）、加（Addition）、减（Subtraction)“，这也是 Python 里的运算优先级。一个常见的错误是人们以为 PEMDAS 是一个绝对次序，需要依次进行，其实乘除是一级，从左到右，然后加减是一级，从左到右，所以你可以把 PEMDAS 写成 PE (M&#38;D) (A&#38;S）。]]></description>

					<description><![CDATA[0. 依赖安装 yum -y update yum install epel-release yum install sqlite-devel yum install -y zlib-devel.x86_64 yum install -y openssl-devel.x86_64 1. 升级Python 系统默认安装的Python是2.6.6的，我们需要升级到Python2.7，用wget命令从官方下载源文件，然后解压进行编译 wget http://www.python.org/ftp/python/2.7.10/Python-2.7.10.tar.xz unxz Python-2.7.10.tar.xz tar -vxf Python-2.7.10.tar 执行完以上命令会解压得到Python-2.7.10这个文件夹，进入该目录并执行以下命令进行配置 ./configure --enable-shared --enable-loadable-sqlite-extensions --with-zlib 其中--enable-loadable-sqlite-extensions是sqlite的扩展，如果需要使用的话则带上这个选项。 之后执行 vi ./Modules/Setup 找到#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz去掉注释并保存，然后进行编译和安装 make &#38;&#38; make install 安装好Python2.7之后我们需要先把Python2.6备份起来，然后再对yum的配置进行修改，如果不进行这一步操作的话，执行yum命令将会提示你Python的版本不对。 执行以下命令，对Python2.6进行备份，然后为Python2.7创建软链接 mv /usr/bin/python /usr/bin/python2.6.6 ln -s /usr/local/bin/python2.7 [&#8230;]]]></description>
