Python - Make new Pandas Index with passed location deleted

Parameters:

• loc ? The location(s) to delete. Can be an integer or array of integers.

Deleting a Single Element

Here's how to delete a single element from a Pandas Index ?

import pandas as pd

# Creating the index
index = pd.Index([15, 25, 35, 45, 55])

# Display the original index
print("Original Pandas Index...")
print(index)

# Delete element at position 2 (3rd element: 35)
new_index = index.delete(2)
print("\nAfter deleting element at position 2...")
print(new_index)

Original Pandas Index...
Index([15, 25, 35, 45, 55], dtype='int64')

After deleting element at position 2...
Index([15, 25, 45, 55], dtype='int64')

Deleting Multiple Elements

You can also delete multiple elements by passing a list of positions ?

import pandas as pd

# Creating the index
index = pd.Index(['A', 'B', 'C', 'D', 'E'])

print("Original Index:")
print(index)

# Delete elements at positions 1 and 3
new_index = index.delete([1, 3])
print("\nAfter deleting positions 1 and 3:")
print(new_index)

Original Index:
Index(['A', 'B', 'C', 'D', 'E'], dtype='object')

After deleting positions 1 and 3:
Index(['A', 'C', 'E'], dtype='object')

Complete Example

Here's a comprehensive example showing various operations with the delete method ?

import pandas as pd

# Creating the index
index = pd.Index([15, 25, 35, 45, 55])

# Display the index
print("Pandas Index...")
print(index)

# Return the number of elements in the Index
print("\nNumber of elements in the index...")
print(index.size)

# Return a tuple of the shape of the underlying data
print("\nA tuple of the shape of underlying data...")
print(index.shape)

# Deleting a single index at 3rd position i.e. index 2
print("\nRemaining Index after deleting an index at location 3rd (index 2)...")
print(index.delete(2))

Pandas Index...
Index([15, 25, 35, 45, 55], dtype='int64')

Number of elements in the index...
5

A tuple of the shape of underlying data...
(5,)

Remaining Index after deleting an index at location 3rd (index 2)...
Index([15, 25, 45, 55], dtype='int64')

Key Points

• The delete() method returns a new Index object
• The original Index remains unchanged
• Positions are zero-indexed (first element is at position 0)
• You can delete single or multiple elements at once

Conclusion

The delete() method provides an easy way to create a new Pandas Index with specific elements removed. It's useful for data cleaning and index manipulation tasks while preserving the original Index structure.
