    You’ll want an online connection for the following couple of steps. obtain an exceptional Darth Vader picture from the internet, and confirm to put it aside to the home\pi folder the place your Python courses can be found. Take distinctive observe of the filename. After downloading the picture, set up the fim image-viewing software program in your Raspberry Pi: pi@raspberrypi ~ $ sudo apt-get -y set up fim observe ensure you comprise a line on the most sensible of this system to import the os module. while it’s performed, try that fim works from Terminal: pi@raspberrypi ~ $ fim Darth_Vader. jpg notice while fim is working, you want to press Esc (escape) to go out. in the event you go out fim, the monitor will show remnants of the picture. It’s a humorous factor, that you could repair by way of grabbing considered one of your home windows via the identify bar and swiping it round the monitor to erase the picture remnants and go back it to the traditional Raspbian machine visual appeal. within the Guessing video game, since you have to name fim out of your Python application, upload a line to import the os module on the best of this system: import os subsequent, edit the game_over functionality to exhibit the picture. The game_over functionality is named basically whilst the participant guesses incorrectly 5 occasions: def game_over(): print("You misplaced! ") print("Better success subsequent time!
