## Rename

This function gives one or more columns new names. It returns a DataFrame with the renamed and original columns.

```{python}
from siuba import _, rename, select
from siuba.data import mtcars

small_cars = mtcars[["mpg", "cyl", "hp"]]
```

For example, the code below renames `mpg` to be uppercase, while keeping the other columns of data.

```{python}
small_cars >> rename(MPG = "mpg")
```

It is equivalent to renaming in a select, while also selecting all other columns.

```{python}
small_cars >> select(_.MPG == _.mpg, _.cyl, _.hp)
```
