This will create a horizontal table like this:
| | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| --- | --- | ---- | --- | --- | ------ | --- | ------ | ---- | ---- |
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
@ -122,7 +123,7 @@ This will give us a table like this:
**Note** that we can also get this table layout by transposing the previous table, eg. by writing
```python
df = pd.DataFrame([a,b]).T..rename(columns={ 0 : 'A', 1 : 'B' })
df = pd.DataFrame([a,b]).T.rename(columns={ 0 : 'A', 1 : 'B' })
```
Here `.T` means the operation of transposing the DataFrame, i.e. changing rows and columns, and `rename` operation allows us to rename columns to match the previous example.
