PyGame in Raspberry using Mouse and Keyboard

I was actually trying to write a simple program which reads the input from keyboard and mouse to Pygame python program. when I searched , found its easy and within a few lines of code in Python we can able to control the movements of an image object in python.

The function image.load can load the image to the screen.
image.get.rect() get the rectangle coordinates of the image position. 

Event 'pg.key.get_pressed' reads the key press events and 'ÍF' clause checks which key has been given as inputs in the below program.

The same mouse click event also capturing inside the while loop which runs till the variable 'running' is true.

Based on the key inputs the rectangle image object position coordinates were changed to make movements to the image.

Looking for how to build Python program games for Raspberry

I am thinking of Python Program games for Raspberry Pi. Searching google a lot for this nowdays. But looks like a bit of logical thinking required for a building games . But still found PYGAME looks easy to build some simple games http://pygame.org/wiki/tutorials
 
Pygame is a set of Python modules designed for writing games. Pygame adds functionality on top of the excellent SDL library. This allows you to create fully featured games and multimedia programs in the python language. Pygame is highly portable and runs on nearly every platform and operating system.
 
Looking to set up a game somehow with my logical skills and that interface with external joystick connected to Raspberry Pi...

Raspberry Pi + Relay Board to turn on 220v bulb from python Web page

To play with 220V , we should be a little careful and need to take all precautions with testers to check to 220v supply. This experiment we need to have Raspberry Pi ( already we have) and Relay Board which actually drive the switch and break the ciruit based on the 7th Pin voltage in GPIO pin.
 
Programs which we are gointo use same the Pyhon program we used to blink the LED from Flask python webpage
 
 
Only difference we used the Raspberry Pi GPIO pins 5v(2nd pin),Ground(6th pin), 7th pin to drive the relay a shown in the pictures.
