INTRODUCTION

Raspberry  Pi is a mini computer, which features a Broadcom system on chip (SoC) with ARM-compatible Central Processing Unit uses ARM1176JZF-S core. Raspberry Pi requires an Operating system. In the aim of cost reduction, the Raspberry Pi omits any onboard non-volatile memory used to store the bootloaders, Linux Kernels, and file systems as seen in more traditional embedded systems. Rather, an SD/MMC card slot is provided for this purpose. After boot, as per the OS installed, Raspberry Pi will be executed.

Python is one of the popular languages in the world. It is highly used in every environment. Raspberry Pi use Python from both IDE (Integrated Development Environment) and from the terminal. Python comes with simple IDE called IDLE. Both the Python version 2 IDLE and 3 IDLE are available.
