多行文本无法显示在视图中

Multiple line text unable to show in view

我正在制作一个 python 项目,我需要在屏幕上打印规则。我正在使用 simplegui 模块,这就是我所拥有的。

text = """You will be given a number
    and a number of operations. The number
    on the top is the answer to the problem.
    You must fill the blanks with numbers that
    make the answer. Hit enter when you are 
    done, hit delete to go back."""
canvas.draw_text(text, (150, 250), 30, 'white')

它给了我错误:

ValueError: text may not contain non-printing characters

我该如何修复这个错误?

draw_text()函数不能绘制多线。您必须逐行绘制。

但是……我写了一个绘制多线的函数: draw_text_multi() 您必须导入 simplegui_lib_draw 模块,因为它不是 CodeSkulptor 的功能。

try:
    import simplegui

    import user40_AeChfAkzlcqs3wG as simplegui_lib_draw
except ImportError:
    import SimpleGUICS2Pygame.simpleguics2pygame as simplegui

    import SimpleGUICS2Pygame.simplegui_lib as simplegui_lib_draw

def draw(canvas):
    …
    draw_text_multi(canvas,
                    """line 1
line 2
line 3""", (x, y), size, 'white', 'serif')
    …
