我正在為我的學校專案優化我的代碼。我正在嘗試使用 Python 圖形庫繪制網格。當我運行回圈時，它會繼續添加行，但 x1 和 x2 值不會像我需要的那樣恢復到它們的原始值。它在行的最后一個正方形的 (x2, y2) 點擴展下一行。任何有關我如何解決此問題的見解將不勝感激！
import random, graphics
from graphics import *
x1 = 5
x2 = 65
y1 = 5
y2 = 65
def make_square(x1, x2, y1, y2):
location = graphics.Rectangle(graphics.Point(x1, y1), graphics.Point(x2, y2))
location.draw(win)
win = graphics.GraphWin("Minesweeper", 545, 570)
win.setBackground(color_rgb(250, 249, 246))
for i in range(9):
for j in range(9):
make_square(x1, x2, y1, y2)
x1 = x1 60
x2 = x2 60
y1 = y1 60
y2 = y2 60
win.getMouse() # Pause to view result, click on window to close it
win.close() # Close window when done
uj5u.com熱心網友回復：
因此，在開始繪制新行時，您想要重置x1and x2，這是有道理的，因為下一行將從與前一行相同的 x 位置開始。您是否嘗試將您的x1 = 5and添加x2 = 65到外部 for 回圈的開頭，而不是在回圈外定義它們？
這樣看：你y在外回圈之外定義，因為它在行上回圈，你x在內回圈外定義，因為它在列上回圈：
import random, graphics
from graphics import *
def make_square(x1, x2, y1, y2):
location = graphics.Rectangle(graphics.Point(x1, y1), graphics.Point(x2, y2))
location.draw(win)
win = graphics.GraphWin("Minesweeper", 545, 570)
win.setBackground(color_rgb(250, 249, 246))
y1 = 5
y2 = 65
for i in range(9):
x1 = 5
x2 = 65
for j in range(9):
make_square(x1, x2, y1, y2)
x1 = x1 60
x2 = x2 60
y1 = y1 60
y2 = y2 60
win.getMouse() # Pause to view result, click on window to close it
win.close() # Close window when done
