Python: How do I do specifically do the following for my code:

$1.$ Have a GUI asking for the amount of lakes, mountains, AND rivers to be RANDOMLY generated.

$2.$ Lower the 'island' land generating circles $($beach$/$sand$,$ grass$)$ to $0,0$ on the grid $($prevent generating lakes$/$mountains off of land$).$

$3.$ INCREASE the size of the circles $3$ times than it currently already is$,$ to take up more of the grid. AKA, circles widened three times than they already are.

$4.$ Have "rivers" cut through ENTIRE island $($slice in half, not cut half way and begin another cut$).$

$5.$ Make the mountains triangles instead of circles.

Really need help on this. My code so far:
