python - 如何修复 Python 散点图中的“列表索引超出范围”错误？

Question

你能看看我的代码并告诉我收到“列表索引超出范围”错误的原因吗？

fig, ax = plt.subplots(figsize=(10,5))
view_count = dodo_data['view_count']
like_count = dodo_data['like_count']
colors = ['r', 'k', 'b', 'g']

ax.legend()
ax.set_xlabel('View Count')
ax.set_ylabel('Like Count', rotation=0, labelpad=55)

for i in range(len(view_count)):
    plt.plot(view_count[i], like_count[i], 'o', color=colors[i])

问题出在colors[i]. 您已经习惯于i遍历view_count列的长度。而是尝试使用单独的迭代器来索引colors列表，该列表迭代len列表colors。

我已经尝试使用示例数据，我将在下面发布。希望能帮助到你！！

from pandas import DataFrame

Data = {'view_count':  [1,2,3,4,5],
        'like_count': [6,7,8,9,10],
        }

dodo_data = DataFrame (Data, columns = ['view_count','like_count'])

print(dodo_data)

import matplotlib.pyplot as plt
import random

fig, ax = plt.subplots(figsize=(10,5))
view_count = dodo_data['view_count']
like_count = dodo_data['like_count']
colors = ['r', 'k', 'b', 'g']

ax.legend()
ax.set_xlabel('View Count')
ax.set_ylabel('Like Count', rotation=0, labelpad=55)

for i in range(len(view_count)):
    plt.plot(view_count[i], like_count[i], 'o', color=colors[random.sample(range(len(colors)),1)[0]])
