Python - Create a new view of the Pandas Index

To create a new view of the Pandas Index, use the index.view() method. At first, import the required libraries −

import pandas as pd

Creating Pandas index −

index = pd.Index([50, 10, 70, 110, 90, 50, 110, 90, 30]) 

Display the Pandas index −

print("Pandas Index...\n",index)

Create a new view −

res = index.view('uint8') 

Displaying the new view −

print("\nThe new view...\n",res)

It shares the same underlying values −

print("\nView for 0th index...\n",res[0]) print("\nView for 1st index...\n",res[1])

Example

Following is the code −

import pandas as pd # Creating Pandas index index = pd.Index([50, 10, 70, 110, 90, 50, 110, 90, 30]) # Display the Pandas index print("Pandas Index...\n",index) # Return the number of elements in the Index print("\nNumber of elements in the index...\n",index.size) # Return the dtype of the data print("\nThe dtype object...\n",index.dtype) # Create a new view res = index.view('uint8') # displaying the new view print("\nThe new view...\n",res) # shares the same underlying values print("\nView for 0th index...\n",res[0]) print("\nView for 1st index...\n",res[1])

Output

This will produce the following output −

Pandas Index... Int64Index([50, 10, 70, 110, 90, 50, 110, 90, 30], dtype='int64') Number of elements in the index... 9 The dtype object... int64 The new view...
