Python | Pandas Panel.size

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.

In Pandas Panel.size gives the number of rows if Series. Otherwise return the number of rows times number of columns if DataFrame.

Syntax: Panel.size

Parameters: None

Returns: Returns value in int representing the number of elements in this object.

# importing pandas module  
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]}) 
                      
print("df1 is - \n\n", df1)
  
# Create a 5 * 5 dataframe 
df2 = pd.DataFrame(np.random.rand(10, 2), columns =['a', 'b']) 
print("df2 is - \n\n", df2)

Now, let’s create the Panel using dict of df1 and df2, and get the size of that panel.

print("\nSize of panel['b'] is - ", panel['b'].size)
