Difference Between pop() and remove() in Python

What is pop()?

• Removes an item by index (lists) or key (dictionaries)
• Returns the removed item
• Raises an error if the index/key does not exist

Example with List:

fruits = ["Apple", "Banana", "Cherry"]
removed_fruit = fruits.pop(1)  # Remove item at index 1
print("Removed fruit:", removed_fruit)
print("Updated list:", fruits)

Output:

Removed fruit: Banana
Updated list: ['Apple', 'Cherry']

Example with Dictionary:

user = {"name": "Nishtha", "age": 25}
removed_age = user.pop("age")
print("Removed age:", removed_age)
print("Updated dictionary:", user)

Output:

Removed age: 25
Updated dictionary: {'name': 'Nishtha'}

What is remove()?

• Removes an item by value (lists only)
• Does NOT return anything
• Raises ValueError if the value is not found
• ❌ Not available for dictionaries

Example:

numbers = [10, 20, 30, 20]
numbers.remove(20)  # Remove first occurrence of 20
print("Updated list:", numbers)

Output:

Updated list: [10, 30, 20]
