Python - Find indices where elements should be inserted to maintain order in Pandas Index

PythonServer Side ProgrammingProgramming

To Find indices where elements should be inserted to maintain order in Pandas Index, use the index.searchsorted() method.

At first, import the required libraries −

import pandas as pd

Creating Pandas index −

index = pd.Index([10, 20, 30, 40, 50])

Display the Pandas index −

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

Searchsorted: set the value to insert and get the exact index position where it should be placed −

print("\nThe exact positions where the element should be placed?...\n",index.searchsorted(45))

Example

Following is the code −

import pandas as pd

# Creating Pandas index
index = pd.Index([10, 20, 30, 40, 50])

# 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)

# searchsorted
# set the value to insert and get the exact index position where it should be placed
print("\nThe exact positions where the element should be placed?...\n",index.searchsorted(45))

Output

This will produce the following output −

Pandas Index...
Int64Index([10, 20, 30, 40, 50], dtype='int64')

Number of elements in the index...
5

The exact positions where the element should be placed?...
4
