为了获取已安装库的列表，我在 Jupyter Notebook 中运行以下命令:
!pip list
我得到以下输出:

如何将此结果存储到Pandas Dataframe中？只需复制数据并粘贴到两个列表中即可完成这项工作，但是是否有任何基于代码的替代方案可以实现此目的？简而言之，如何将 pip 命令的结果存储到 Pandas Dataframe 中？
P.S:我提到了here但没有任何帮助。
最佳答案
我们可以使用os模块创建pip列表，然后使用pandas.read_csv和\s+作为分隔符来读取pip列表到数据框中:
import os
import pandas as pd
# create pip list txt
os.system('pip list > pip_list.txt')
# read content into pandas df
df = pd.read_csv('pip_list.txt', sep=r'\s+', skiprows=[1])
# clean up
os.remove('pip_list.txt')
