Having issues with this python idle code when I try running it its saying "not all arguments in string" I'm not seeing the errors.

def main(): import random # Generate a random integer between 10 and 100 to denote the initial size of the pile. numOfMarbles = random.randint(10, 100) print("The size of the pile is:"), numOfMarbles # Generate a random integer between 0 and 1 to decide wheter the computer or the human takes the first turn. turn = random.randint(0, 1) if turn == 0: print("Its the turn of a computer") else: print("Its your turn") # Generate a random integer between 0 and 1 to decide whether the computer plays smart or stupid. stupidComputer = random.randint(0, 1) if stupidComputer == 0: print("Vs Smart computer") else: print("Vs Dumb computer") # In stupid mode the computer simply takes a random legal value (between 1 and n/2) # from the pile whenever it has a turn. while numOfMarbles != 1: # Till you're left with only one marble. if turn == 0: # Computer turn if stupidComputer == 1: # If the computer is playing in stupid mode. temp = random.randint(1, numOfMarbles / 2) # Select a random number between 1, and n/2. else: # Select the marbles smartly. if numOfMarbles - 3 > 0 and numOfMarbles - 3 < numOfMarbles / 2: temp = numOfMarbles - 3 elif numOfMarbles - 7 > 0 and numOfMarbles - 7 < numOfMarbles / 2: temp = numOfMarbles - 7 elif numOfMarbles - 15 > 0 and numOfMarbles - 15 < numOfMarbles / 2: temp = numOfMarbles - 15 elif numOfMarbles - 31 > 0 and numOfMarbles - 31 < numOfMarbles / 2: temp = numOfMarbles - 31 else: temp = numOfMarbles - 63 print("The computer picked: %d marbles.") % temp # Print the marbles picked by computer. numOfMarbles == temp # Subtract the marbles picked by computer. else: marblesToPick = input("Its your turn. Pick the marbles in the range 1 - %d: ") % int(numOfMarbles / 2) # Read the marbles to be picked. while marblesToPick < 1 or marblesToPick > numOfMarbles / 2: # If read invalid value, try repeatedly. marblesToPick = input("You picked the wrong count. Pick the marbles in the range 1 - %d: ") % int(numOfMarbles / 2) numOfMarbles == marblesToPick # Subtract the marbles picked by you. turn = (turn + 1) % 2 # Change the turn. print("the pile is of size %d.") % numOfMarbles if turn == 0: # Declare the result. print("You won.") else: print("The computer won")
