There's a good chance that you already have Python on your operating system.
|
|
|
|
If so, you do not need to install or configure anything else to use Python.
|
|
Having said that, I would strongly recommend that you install the tools and
|
|
libraries described in the guides below before you start building Python
|
|
applications for real-world use. In particular, you should always install
|
|
Setuptools, Pip, and Virtualenv — they make it much easier for you to use
|
|
other third-party Python libraries.
|
|
|
|
.. note:: The use of **Python 3** is *highly* preferred over Python 2. Consider upgrading your applications and infrastructure if you find yourself *still* using Python 2 in production today. If you are using Python 3, congratulations — you are indeed a person of excellent taste.
