Python 乌龟颜色

Question

嘿，我必须在 python 中编写一个程序，该程序需要用户输入行数、列数、正方形边长和三种颜色。然后程序必须根据行数和列数制作一个网格，并以交替的棋盘格图案填充方块。我已将其编码到填充颜色的程度，我想知道是否有人可以帮助我。这是我目前所拥有的：

from turtle import *
t = Turtle()
screen = t.getscreen()

rows = screen.numinput('Number of rows',
                       'How many rows shall there be?', 5, 1, 10)
columns = screen.numinput('Number of columns',
                          'How many columns shall there be?', 5, 1, 10)
side_length = screen.numinput('Length of square side',
                              'How long shall the square sides be?', 30, 10, 50)
first_color = screen.textinput('First color',
                               'What shall the first color be?')
second_color = screen.textinput('Second color',
                                'What shall the second color be?')
third_color = screen.textinput('Third color',
                               'What shall the third color be?')

square_color = ''


def draw_square():
    t.begin_fill()
    t.pendown()
    t.forward(side_length)
    t.left(90)
    t.forward(side_length)
    t.left(90)
    t.forward(side_length)
    t.left(90)
    t.forward(side_length)
    t.color(square_color)
    t.end_fill()
    t.penup()
    t.color('black')
    t.left(90)
    t.forward(side_length)



def draw_board():
    n = 1
    for i in range(int(columns)):
        draw_square()
    for x in range(int(rows - 1)):
        t.goto(0,side_length * n)
            for i in range(int(columns)):
            draw_square()
        n += 1
for i in range(int(columns)):
    for x in range(int(rows)):
        if x + i % 3 == 0:
            square_color = first_color
        elif x + i % 3 == 1:
            square_color = second_color
        elif x + i % 3 == 2:
            square_color = third_color
draw_board()
done()

您拥有所需的所有代码，实际上太多了。你只是没有正确组装它。您需要将您的程序视为一个故事，并以正确的事件顺序讲述该故事，使该故事有意义。以下是我对您的代码进行的修改，以更好地排列顺序以及一些样式调整和代码清理：

from turtle import Turtle, Screen

def draw_square(turtle, length, color):
    turtle.color(color)
    turtle.pendown()

    turtle.begin_fill()
    for _ in range(4):
        turtle.forward(length)
        turtle.left(90)
    turtle.end_fill()

    turtle.penup()
    turtle.forward(length)

def draw_board(turtle, length, colors):
    n = 0

    for row in range(int(rows)):
        turtle.goto(0, length * n)
        for column in range(int(columns)):
            square_color = colors[(column + row) % len(colors)]
            draw_square(turtle, length, square_color)
        n += 1

screen = Screen()

rows = screen.numinput('Number of rows', 'How many rows shall there be?', 5, 1, 10)
columns = screen.numinput('Number of columns', 'How many columns shall there be?', 5, 1, 10)
side_length = screen.numinput('Length of side', 'How long shall the square sides be?', 30, 10, 50)

first_color = screen.textinput('First color', 'What shall the first color be?')
second_color = screen.textinput('Second color', 'What shall the second color be?')
third_color = screen.textinput('Third color', 'What shall the third color be?')

colors = [first_color, second_color, third_color]

turtle = Turtle()
turtle.penup()

draw_board(turtle, side_length, colors)

turtle.hideturtle()

screen.exitonclick()
