Python | Pandas Panel.size

NumPy | Python Methods and Functions

In Pandas, Panel.size will output the number of rows if Series. Otherwise, returns the number of rows multiplied by the number of columns if the DataFrame.

Syntax: Panel.size

Parameters: None

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

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 ]}) 

 

print ( " df1 is - " , df1)

 
# Create a 5 * 5 data frame

df2 = pd.DataF rame (np.random.rand ( 10 , 2 ), columns = [ `a` , ` b` ]) 

print ( "df2 is -" , df2)

Now let`s create a Panel using dict for df1 and df2 and get the size of this panel.

data = { `item1` : df1, ` item2` : df2} 

 
# create a panel

panel = pd.Panel.from_dict (data , orient = `minor`

print ( "panel [` b`] is - " , panel [ `b` ], ``

 

 

print ( "Size of panel [` b`] is - " , panel [ ` b` ]. size) 

 Output:

Code # 2:

# 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` ) < / code>

 

print ( "panel [` b`] is - " , panel [ `b` ], ` `

 

print ( "Size of panel [` b`] is - " , panel [ ` b` ]. size) 

Output:

Code # 3:

# pandas module import

import pandas as pd 

import numpy as np 

 

df1 = pd.DataFrame ({ `a` : [ `Geeks` , ` For` , `geeks` , ` real` ] , 

`b` : [ - 11 , + 1.025 , - 114.48 , 1333 ]}) 

  

df2 = pd.DataFrame ({ `a` : [ ` I` , `am` , `dataframe` , `two` ], 

  `b` : [ 100 , 100 , 100 , 100 ]}) 

 

data = { `ite m1` : df1, `item2` : df2}

 
# create a panel

panel = pd.Panel.from_dict (data, orient = ` minor`

print ( "panel [` b`] is - " , panel [ `b` ]) 

  

print ( "Size of panel [ `b`] is -" , panel [ `b` ] .size)
