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... [ 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... 0
