熊猫重命名列名

Question

I have the following code: buckets = pd.DataFrame(sample.score.unique())

Which produces:

        0
0   0.342
1   0.408
2   0.450
3   0.458
4   0.492
5   0.500

When I try to rename the column with buckets.rename(columns = {'0': 'score'}, inplace = True) the column name 0 is not renamed to score .

How can rename 0 to score ?

Answer 1

就您而言，只需删除列名上的引号

{0: 'scores'}
