This document uses Python 2.7.13 as an example to demonstrate how to install and configure Python in Windows and Linux.
Go to the Python official website and download an appropriate version. In this example, we download Python 2.7.13.
Double click the Python installer package, and install Python as instructed.
(1) Once Python is installed, restart your computer as instructed.
(2) Right-click on the "Computer" or "My Computer" desktop icon, and select Properties > Advanced system settings > Environment Variables. In System variables, locate Path, or click New to create a variable named as such.
(3) Click Edit > Edit Text, and add ;C:\Python27
(replace it with your own Python installation path) to the end of the “Path”.
(4) Click OK.
Click Start (or shortcut: Win+R) > Run (enter cmd
) > OK (or press Enter), enter the Python command in the pop-up window, and press Enter. If Python version information appears, Python 2.7 has been installed successfully.
Linux’s yum comes with Python, so check the default Python version first.
python -V
If it comes with Python 2.7 or above, ignore the following steps. Otherwise (for example, if it comes with Python 2.6.6), enter the following command:
yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel
wget https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz
tar xf Python-2.7.12.tar.xz
cd Python-2.7.12 //Enter the directory
./configure -prefix=/usr/local
make && make install //Install
make clean
make distclean
mv /usr/bin/python /usr/bin/python2.6.6
ln -s /usr/local/bin/python2.7 /usr/bin/python
python
If the information appears as shown below, Python 2.7 has been installed successfully.
Note:
If permission problems occur, try to add
sudo
to the beginning of your command.
