好吧，我检查了问题Remove index name in pandas，但它不适用于我的情况。
所以我有一个df，我用熊猫melt对其进行了归一化，然后用pivot_table对它进行了归一化。现在，我有了以下df，但是我想删除此索引名称variable。
这是df：
df
variable Site Process cap-lo cap-up depreciation ... inv-cost max-grad min-fraction var-cost wacc

我想删除索引上方的variable。我该怎么办？
它可能不是索引名，而是列名...我只想删除变量。
PS：df.index.name = 'blah'执行以下操作：
df
variable Site Process cap-lo cap-up depreciation ... inv-cost max-grad min-fraction var-cost wacc
blah ...

答案 0 :(得分：0)
您可以使用rename_axis：
df = df.rename_axis(None, axis=1)
# df.columns.name = None
# To remove index label
df = df.rename_axis(None, axis=0)
# df.index.name = None
