Python - Create a new view of the Pandas Index

PythonServer Side ProgrammingProgramming

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...
[ 50 0 0 0 0 0 0 0 10 0 0 0 0 0 0 0 70 0
  0 0 0 0 0 0 110 0 0 0 0 0 0 0 90 0 0 0
  0 0 0 0 50 0 0 0 0 0 0 0 110 0 0 0 0 0
  0 0 90 0 0 0 0 0 0 0 30 0 0 0 0 0 0 0]

View for 0th index...
50

View for 1st index...
