To learn python, first learn to deploy its environment, then we will deploy the environment

In Linux, it is installed by default and can be installed by Yum or source if it is not installed.

Yum Installation: yum-y install python

SOURCE Installation:

To download the software first:

wget http://www.python.org/ftp/python/2.6.6/Python-2.6.6.tgz

Tar zxf python-2.6.6.tgz ; CD Python-2.6.6

./configure--prefix=/usr/local/python

Make && make install

To do a soft link:

ln-s/usr/local/python/bin/python/usr/bin/python

Now that Python is installed, let's take a look at how to use it.

python-v can view versions

python can enter the python environment

We can write Python as a script, and call it a Python script.

The suffix of the Python script is. py

We can take a look.

Cat phthon.py

#!/usr/bin/env python

print "Hello World!!!"

This is a simple Python script that outputs "helloworld!"
