This method is used to reshape long-format data to wide. This is the generalized inverse of DataFrame.pivot.
Syntax : pandas.lreshape(data, groups, dropna=True, label=None)
Arguments :
- data : DataFrame
- groups : dict {new_name : list_of_columns}
- dropna : boolean, default True
Below is the implementation of the above method with an example :
Python3
import numpy
import pandas as pd
data = pd.DataFrame({
'hr1': [514, 573],
'hr2': [545, 526],
'team': ['Red Sox', 'Yankees'],
'year1': [2007, 2007],
'year2': [2008, 2008]
})
print(data)
print(pd.lreshape(data, {'year': ['year1', 'year2'],
'hr': ['hr1', 'hr2']}))
