## Installation ## Installation
Most *nix based operating systems come with Python installed (usually Python 2, Python 3 in most recent ones). Replacing the system Python is not recommended and may cause problems. However, different versions of Python can be safely installed alongside the system Python.

A function is called when the name of the function is followed by `()`. For the 'Hello, World!' example, the print function is called with a string as an argument for the first parameter. For the rest of the parameters the defaults are used. A function is called when the name of the function is followed by `()`.

## Things you can do with python ## Things you can do with python
As stated python is a general purpose language. You can use it to do anything you like but one of the major uses of python is in machine learning and artificial intelligence. It is also a popular language in web development with some amazing frameworks like [Django](https://www.djangoproject.com/) and [flask](http://flask.pocoo.org/). It is also a popular scripting language. With its easy to read syntax it is becoming one the most popular programming languages growing rapidly in different fields.
