python数据分析与可视化 import pandas as pd import numpy as np import m

python数据分析与可视化 python数据分析与可视化 import pandas as pd import numpy as np import matplotlib.pyplot as plt # 创建示例数据 data = pd.DataFrame({ 'A': np.random.randn(1000), 'B': np.random.randn(1000), 'C': np.random.randn(1000), }) # 计算每列的平均值 data_mean = data.mean() # 绘制直方图 data['A'].plot(kind='hist', bins=30, color='lightblue', edgecolor='black') # 设置标题和标签 plt.title('Histogram of A') plt.xlabel('Value') plt.ylabel('Frequency') # 显示图形 plt.show() 这段代码首先导入了必要的Python库，并创建了一个包含随机数的DataFram

回答: 这段代码是在Python中导入pandas和numpy库。通过"import pandas as pd"和"import numpy as np"语句，我们可以使用pd和np作为这两个库的别名，以便在后续的代码中更方便地调用它们的功能。 #### 引用[.reference_title] - *1* *3* [Python数据挖掘Pandas](https://blog.csdn.net/ZGL_cyy/article/details/125724975)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v91^insertT0,239^v3^insert_chatgpt"}} ] [.reference_item] - *2* [pandas常用的方法（按功能）](https://blog.csdn.net/qq_43115961/article/details/126775471)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v91^insertT0,239^v3^insert_chatgpt"}} ] [.reference_item] [ .reference_list ]
