Python | Pandas Panel.cumprod ()

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:

# pandas module import

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} 
   
  # create a panel  
   panel   =   pd. Panel.from_dict (data, orient   =   `minor`  ) 
   
   print   (panel [  `b`  ])   
  
   print   (  ""  , panel [  `b`  ]. cumprod (axis   =   0  ))

Output:

Code # 2:

       # pandas module import  
   import   pandas as pd 
   import   numpy as np 
   
   df1   =   pd.DataFrame ({  `a`  : [ ` Geeks`  ,   `For`  ,  ` geeks`  ], 
    `b`  : np.random.randn (  3  )}) 
   
   data   =   { ` item1`  : df1,   `item2`  : df1} 
   
  # create a panel  
   panel   =   pd.Panel.from_dict (data, orient   =   `minor`  ) 
    
   print   (panel [  `b`  ]) 
   
   
   print   (  ""  , panel [ ` b`  ]. cumprod (axis   =   0  ))
