pivot是一个很棒的功能，但会导致一个数据框包含一些我不需要的额外信息:如何在下面实现?我不需要"bar"或"foo"，并且我想使df更加简洁.谢谢.
pivot is a great function but results in a dataframe with a few extra info that I don't need: How can I achieve below? I do not need "bar" or "foo", and I want to make the df more concise. Thanks.
推荐答案
将index和columns名称设置为None:
df.index.name = None df.columns.name = None或使用 rename_axis :
df = df.rename_axis(None).df.rename_axis(None, axis=1)
