Python Built-in Methods – Python List pop() Method

By on Monday, May 17, 2021

Python List pop() Method

Removes an item at specified index

Usage

The pop() method removes a single list item at specified index and returns it. If no index is specified, pop() method removes and returns the last item in the list.

Syntax

list.pop(index)

Parameter Condition Description
index Optional An index of item you want to remove.
Default value is -1

Return Value

The pop() method returns the value of removed item.

Examples


# Remove 2nd list item
L = ['red', 'green', 'blue']
L.pop(1)
print(L)
# Prints ['red', 'blue']

You can also use negative indexing with pop() method.

# Remove 2nd list item
L = ['red', 'green', 'blue']
L.pop(-2)
print(L)
# Prints ['red', 'blue']

When you remove an item from the list using pop(), it removes it and returns its value.

L = ['red', 'green', 'blue']
x = L.pop(1)

# removed item
print(x)
# Prints green

When you don’t specify the index on pop(), it assumes the parameter to be -1 and removes the last item.

L = ['red', 'green', 'blue']
L.pop()
print(L)
# Prints ['red', 'green']

Two Machine Learning Fields

There are two sides to machine learning:

  • Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
  • Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
