Plotas su Python

#IT's very important to choose a correct file location:
location=r"C:\Users\Vartotojas\Desktop\EnolaProject\Matematikos idejos\Visual Tools\2 budai paaiskinti skritulio plotui\integral division\frames\intos"

#a .gif file will be saved as plotas.gif"
#It takes about 2 minutes to render 100 frames because part of picture is taken from thre result of .tex compilation
