我有一个excel文件,我用pandas读取并转换为数据框。以下是数据帧的示例:
| | salads_count | salads_count | salads_count | carrot_counts | carrot_counts | carrot_counts |
|---------------|--------------|--------------|--------------|---------------|---------------|---------------|
| | 01.2016 | 02.2016 | 03.2016 | 01.2016 | 02.2016 | 03.2016 |
| farm_location | | | | | | |
| sweden | 42 | 41 | 43 | 52 | 51 | 53 |
我用下面的代码设法将其放入一个多索引中,但有些列是重复的(例如,salads_count出现了几次):
arrays = [df.columns.tolist(), df.iloc[0].tolist()]
tuples = list(zip(*arrays))
index = pd.MultiIndex.from_tuples(tuples)
df.columns = index
| | salads_count | | | carrot_counts | | |
|---------------|--------------|---------|---------|---------------|---------|---------|
| | 01.2016 | 02.2016 | 03.2016 | 01.2016 | 02.2016 | 03.2016 |
| farm_location | | | | | | |
| sweden | 42 | 41 | 43 | 52 | 51 | 53 |
| | 01.2016 | | 02.2016 | | | |
|---------------|--------------|--------------|--------------|-------------|---|---|
| | carrot_count | salads_count | carrot_count | salad_count | | |
| farm_location | | | | | | |
| sweden | 52 | 42 | 51 | 41 | | |
