Explanation / Answer

import turtle s = turtle.Screen() t = turtle.Turtle() length = None while not length: try: length = float(input('Enter your preferred turtle line length: ')) except ValueError: print('You need to enter a number') width = None while not width: try: width = int(input('Enter your preferred turtle line width: ')) except ValueError: print('You need to enter a positive integer') else: if width < 1: print('You need to enter a positive integer') width = None color = None while not color: color = input('Enter your preferred turtle line color: ') try: t.pencolor(color) except: print('You need to enter a color that I know.') color = None shape = None while not shape: shape = input('Specify whether you want to draw a line, triangle, or square: ') if shape.lower() not in ['line', 'triangle', 'square']: shape = None print('I only draw lines, triangles and squares!') t.pensize(width) if shape == 'line': t.forward(length) elif shape == 'triangle': t.forward(length) t.right(120) t.forward(length) t.right(120) t.forward(length) else: t.forward(length) t.right(90) t.forward(length) t.right(90) t.forward(length) t.right(90) t.forward(length) s.exitonclick()
