A virtual environment is a light-weight, self-contained Python installation. The main motivation for virtual environments is to allow different projects to have control over the versions of installed Python packages, without interfering with other Python projects installed on the same host. A virtual environment consists of a directory containing a symbolic link to (Unix), or a copy of (Windows), an existing Python installation, together with an empty site-packages directory into which Python packages specific to this virtual
environment can be installed. A second motivation for virtual environments is that users can create a virtual environment without needing administrator rights on their system, making it easy for them to install packages locally.

Overview of this book
Experienced programmers want to know how to enhance their craft and we want to
help them start as apprentices with Python. We know that before mastering Python you need to learn the culture and the tools to become a productive member of any Python project. Our goal with this book is to give you a practical and thorough introduction to Python programming, providing you with the insight and technical craftsmanship you need to be a productive member of any Python project. Python is a big language, and it’s not our intention with this book to cover everything there is to know. We just want to make sure that you, as the developer, know the tools, basic idioms and of course the ins and outs of the language, the standard library and other modules to be able to jump into most projects.
