Question

Your (turtle) program in python must include: Create four Red turtles and four Blue turtles using one or more lists. • Start each of the Red turtles at a different random location on the left side of the screen within the range of the square formed by (-100, 100) and (0, -100) and each of the Blue turtles at a random location on the right side of the screen within the range of the square formed by (0, 100) and (100, -100). • Each of the red and blue turtles should move randomly. • Draw a boundary for the game as a circle with a 300 unit radius. You will use an invisible turtle to do this. It does not count as one of the turtles on either team. • If a turtle hits the border the turtle should have its color changed to black and should jump back to the center of the screen (0, 0) and continue moving. • All the turtles will move the same speed. • The turtles should continue moving until 1000 time units have elapsed.

Code:

import random
import pandas as pd
import math

blue_turtle = [['blue1', 0, 0, 'blue'], ['blue2', 0, 0, 'blue'], ['blue3', 0, 0, 'blue'], ['blue4', 0, 0, 'blue']]
red_turtle = [['red1', 0, 0, 'red'], ['red2', 0, 0, 'red'], ['red3', 0, 0, 'red'], ['red4', 0, 0, 'red']]
red_data = pd.DataFrame(red_turtle, columns= ['RTurt','X', 'Y', 'Color']) # Red Turtles dataframe
blue_data = pd.DataFrame(blue_turtle, columns= ['BTurt','X', 'Y', 'Color']) # Blue Turtles dataframe

# Initial coordinate generator for blue turtles
for k in blue_data['BTurt']:
  blue_data.loc[blue_data['BTurt'] == k, 'X'] = random.choices(range(0,100))
  blue_data.loc[blue_data['BTurt'] == k, 'Y'] = random.choices(range(-100,0))

# Initial coordinate generator for red turtles

  red_data.loc[red_data['RTurt'] == m, 'Y'] = random.choices(range(0,100))

print(red_data)
print(blue_data)
