Panel.cumprod() is used to return a DataFrame or Series of the same size that contains the accumulated product.
Syntax: Panel.cumprod (axis = None, skipna = True, * args, ** kwargs)
Parameters:
axis: The index or the name of the axis. 0 is equivalent to None or `index`.
skipna: Exclude NA / null values. If an entire row / column is NA, the result will be NA.
Returns: Cumprod of DataFrame or Panel
Code # 1:

import pandas as pd
import numpy as np
df1 = pd.DataFrame ({ ` a` : [ `Geeks` , ` For` , `geeks` , ` for` , `real` ],
`b` : [ 11 , 1.025 , 333 , 114.48 , 1333 ]})
data = { ` item1` : df1, `item2` : df1}
panel = pd. Panel.from_dict (data, orient = `minor` )
print (panel [ `b` ])
print ( "" , panel [ `b` ]. cumprod (axis = 0 ))

Output:

# create a panel
panel = pd.Panel.from_dict (data, orient = `minor` )
print (panel [ `b` ])
