在保留两个for循环的条件下，怎么让柱状图正常画出

njw5

import turtle


# Function that draws the turtle
def drawBar(t, height, color):
    # Get turtle t to draw one bar
    # of height

    # Start filling this shape
    t.fillcolor(color)
    t.begin_fill()
    t.left(90)
    t.forward(height)
    t.write(str(height))
    t.right(90)
    t.forward(40)
    t.right(90)
    t.forward(height)
    t.left(90)

    # stop filling the shape
    t.end_fill()

# Driver Code
s_list=[423, 117,1235, 96, 134,789, 354]
for i in range(7):
    count = s_list[i]
    xs = [count]
    clrs = ["green", "red", "yellow", "black",
            "pink", "brown", "blue"]

    maxheight = max(xs)
    numbers = len(xs)
    border = 100

# Set up the window and its
# attributes
    wn = turtle.Screen()
    wn.setworldcoordinates(0 - border, 0 - border,
                           40 * numbers + border,
                           maxheight + border)

    tess = turtle.Turtle()
    tess.pensize(3)

    for x in range(len(xs)):
        drawBar(tess, xs[x],
                clrs[x])

在你的代码中，绘制柱状图的部分有一些问题。首先，你应该使用循环变量 `i` 来获取每个元素的高度和颜色，而不是直接使用列表本身。另外，在绘制每个柱状图时，你应该使用索引 `x` 来获取对应的高度和颜色。

以下是修改后的代码：

1. import turtle
3. # Function that draws the turtle
4. def drawBar(t, height, color):
5.     # Get turtle t to draw one bar
6.     # of height
8.     # Start filling this shape
9.     t.fillcolor(color)
10.     t.begin_fill()
11.     t.left(90)
12.     t.forward(height)
13.     t.write(str(height))
14.     t.right(90)
15.     t.forward(40)
16.     t.right(90)
17.     t.forward(height)
18.     t.left(90)
20.     # stop filling the shape
21.     t.end_fill()
23. # Driver Code
24. s_list = [10, 30, 20, 40, 50, 15, 25]
25. clrs = ["red", "green", "blue", "yellow", "orange", "purple", "pink"]
27. maxheight = max(s_list)
28. numbers = len(s_list)
29. border = 100
31. # Set up the window and its attributes
32. wn = turtle.Screen()
33. wn.setworldcoordinates(0 - border, 0 - border,
34.                        40 * numbers + border,
35.                        maxheight + border)
37. tess = turtle.Turtle()
38. tess.pensize(3)
40. for x in range(len(s_list)):
41.     drawBar(tess, s_list[x], clrs[x])
42.    
43. turtle.done()
