尝试平均字典中每个键的值后，无法正确绘制图形

Question

我试图平均出键中的值，并将它们放入列表中。然而，当我试图将这些值放到一个图表中时，它只会给我带来很多错误

import numpy as np
import matplotlib.pyplot as plt

academic = {"Jane": [75, 80, 85, 60],
            "John": [60, 68, 74, 80],
            "Jerome": [81, 63, 77, 50],
            "Jason": [55, 76, 67, 60],
            "Jessica": [62, 45, 68, 55],
            "Joanne": [52, 47, 51, 70]}
for result in academic:
    average = round((academic[result][0]+academic[result][1]+academic[result][2]+academic[result][3])/4)
    academic[result] = average
    y = np.arange(len(academic))
    x = list(academic.values())
    plt.bar(x, y)
    plt.bar(x, y, align='center')
    plt.xticks(x, academic)
    plt.show()

Answer 1

你的缩进是错的，就像斯蒂芬·劳赫说的，但我认为你也把x和y混淆了。把它们换过来对我来说更有意义

import numpy as np
import matplotlib.pyplot as plt

academic = {"Jane": [75, 80, 85, 60],
            "John": [60, 68, 74, 80],
            "Jerome": [81, 63, 77, 50],
            "Jason": [55, 76, 67, 60],
            "Jessica": [62, 45, 68, 55],
            "Joanne": [52, 47, 51, 70]}
for result in academic:
    average = round((academic[result][0]+academic[result][1]+academic[result][2]+academic[result][3])/4)
    academic[result] = average
x = np.arange(len(academic))
y = list(academic.values())
plt.bar(x, y, align='center')
plt.xticks(x, academic)
plt.show()
