# Reshaping
|
|
|
|
Reshaping transforms the structure of a DataFrame without changing its data. `pivot()` and `pivot_table()` convert long-format data to wide format. `melt()` does the reverse, converting wide to long. `stack()` and `unstack()` move index levels to columns or vice versa. Reshaping is often needed to prepare data for specific visualizations or models.
