Question

complete the code

1. The instructions to a turtle can be encoded in a string. Complete Asn4_5 as follows:

In main() the user will be prompted to enter instructions to a turtle as follows. The instructions will be entered in a loop that will end when the user enters quit or Quit at the first prompt.

1. The first prompt will ask for a color. If the user enters quit or the user enters Quit the program will exit.
2. The second prompt will ask the user to enter a sequence of commands, separated by commas. Commands may be in uppercase or lowercase and will be in the form of cd*, where c represents a one-character turn, move, or pen command followed by zero or more digits, as described below:
   1. If the command is U or the command is D, it means pick the pen up or put it down; it is not followed by any digits.
   2. If the command is L or the command is R, it will be followed by an integer that determines the number of degrees to turn.
   3. If the command is F or the command is B, it will be followed by an integer that determines the distance to move forward or backward.

After the user enters the command string, main() will split the string into a list of commands. For each command, it will call move_turtle(t, cmd), where t is a turtle and cmd.

Save your Asn4 folder, with the completed programs, by 5 minutes after class time on the due date.

The following shows an interaction in which the user moved the turtle back 100 units, drew a red square, then moved the turtle forward 100 units and drew a green diamond. Note that the user can enter upper or lowercase commands. Also, notice that the command string does not have any spaces.

Please enter a color: red

Enter commands separated by commas: U,B100,D

Please enter a color: red

Enter commands separated by commas: L90,F50,L90,F50,L90,F50,L90,F50

Please enter a color: red

Enter commands separated by commas: U,f100,D

Please enter a color: green

Enter commands separated by commas: L45,f50,L90,F50,L90,F50,L90,F50,R45

Please enter a color: Quit

import turtle

def move_turtle(t, move):
'''
Moves turtle t according to move; t is a turtle;
move is a string where the first character is a command.
If the string is longer than one character, the remaining
characters are digits. Those digits are an integer that
determines either number of degrees to turn or number of
units to move, depending on the command

Answer 1

THE CODE FOR THE ABOVE QUESTION IS:

import turtle

def move_turtle(t, move):
    # coverting to uppercase
    move = move.upper()

    # extracting the command
    c = move[0]
  
    # executing the respective command using if-elif-else
    if c == 'U':
        t.up()                # picking up the turtle's pen
    elif c == 'D':
        t.down()              # putting down the turtle's pen
    elif c == 'L':
        d = int(move[1:])     # extracting the decimal number
        t.left(d)             # moving the turtle left
    elif c == 'R':
        d = int(move[1:])     # extracting the decimal number
        t.right(d)            # moving the turtle right
    elif c == 'F':
        d = int(move[1:])     # extracting the decimal number
        t.forward(d)          # moving the turtle forward
    elif c == 'B':
        d = int(move[1:])     # extracting the decimal number
        t.backward(d)         # moving the turtle backward
    else:
        pass

def main():
    color = ''
    myTurtle = turtle.Turtle() # creating a turtle object
  
    while color != 'quit' or color != 'Quit':
    
        color = input('Please enter a color: ')
        if color == 'quit' or color == 'Quit':
            break
        myTurtle.color(color)   # setting color of the turtle
      
        # taking the commands as input and splittin them by comma
        commands = input('Enter commands separated by commas: ').split(',')
      
        # looping each command and executing it one by one
        for command in commands:
            move_turtle(myTurtle, command)

if __name__ == '__main__':
    main()
