Python | Pandas Panel.cumsum()

In Pandas, Panel is a very important container for three-dimensional data. The names for the 3 axes are intended to give some semantic meaning to describing operations involving panel data and, in particular, econometric analysis of panel data.

Panel.cumsum() function is used to returns a DataFrame or Series of the same size containing the cumulative sum.

Syntax: Panel.cumsum(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: Cumsum of DataFrame or Panel

Code #1:




# importing pandas module 
import pandas as pd 
import numpy as np
  
df1 = pd.DataFrame({'a': ['Geeks', 'For', 'neveropen', 'for', 'real'], 
                    'b': [11, 1.025, 333, 114.48, 1333]})
                      
data = {'item1':df1, 'item2':df1}
  
# creating Panel 
panel = pd.Panel.from_dict(data, orient ='minor')
  
print(panel['b'])
  
print("\n", panel['b'].cumsum(axis = 0))


Output:

 

Code #2:




# importing pandas module 
import pandas as pd 
import numpy as np
  
df1 = pd.DataFrame({'a': ['Geeks', 'For', 'neveropen'], 
                    'b': np.random.randn(3)})
                      
data = {'item1':df1, 'item2':df1}
  
# creating Panel 
panel = pd.Panel.from_dict(data, orient ='minor')
  
print(panel['b'])
  
  
print("\n", panel['b'].cumsum(axis = 0))
