Question

我有一个要从Linux sosreport 获取的文件，我想制作一个饼图，问题是将文件转换为CSV时，它不包含逗号并创建它作为1列。

文件如下：

将meminfo文件转换为CSV文件，如下所示：

df.to_csv('meminfo.csv', header=False, index=False)

并且我也在尝试命名列，但我不能。

对不起，但我是数据可视化领域的新手

通过使用python引擎，您可以将分隔符定义为正则表达式。添加更多字段来处理标题，索引和数据类型，这应该可以为您提供所需的信息

>>> df=pd.read_csv("test.txt", engine="python", sep=r":?\s+", index_col=0,
... names=["field", "value", "unit"],
... dtype={"field":str, "value":int, "unit":str})
>>> 
>>> df
                       value  unit
field
