I am having trouble with my program in python I can't figure out how to print the square of my side = s can somebody suggest anything here is my code so far

class Square:

def __init__(self): self.__side = 2 def set_side(self, s): if s <= 0: raise ValueError("Side must be longer than 0") self.__side = s

def get_side(self): return self.__side

def get_area(self): return self.__s**2

def main(): x = Square() x.set_side(20) print(x.get_side()) main()
