Python Pandas - Return the integer indices that would sort the index

PythonServer Side ProgrammingProgramming

To return the integer indices that would sort the index, use the index.argsort() method in Pandas. At first, import the required libraries −

import pandas as pd

Creating Pandas index −

index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'], name ='Products')

Display the Pandas index −

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

Return the integer indices that would sort the index −

res = index.argsort()

Example

Following is the code −

import pandas as pd

# Creating Pandas index
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'], name ='Products')

# Display the Pandas index
print("Pandas Index...
",index) # Return the number of elements in the Index print("
Number of elements in the index...
",index.size) # Return the dtype of the data print("
The dtype object...
",index.dtype) res = index.argsort() # Return the integer indices that would sort the index print("
The integer indices to sort the index...
",res) print("
Ordered..
",index[res])

Output

This will produce the following output −

Pandas Index...
Index(['Electronics', 'Accessories', 'Decor', 'Books', 'Toys'], dtype='object', name='Products')

Number of elements in the index...
5

The dtype object...
object

The integer indices to sort the index...
[1 3 2 0 4]

Ordered..
Index(['Accessories', 'Books', 'Decor', 'Electronics', 'Toys'], dtype='object', name='Products')
