How to remove an element from a list by index?

 

To remove an element from a list by its index in Python, you can use the pop() method of the list or use slicing to create a new list without the element at the specified index. Here are two examples:

Using the pop() method:

The pop() method removes and returns the element at the specified index. If you don't need the removed element, you can use pop() without assigning the result to a variable.

python

# Create a list
my_list = [10, 20, 30, 40, 50]

# Remove the element at index 2 (30) and store it in a variable
removed_element = my_list.pop(2)

# Print the modified list and the removed element
print("Modified List:", my_list)
print("Removed Element:", removed_element)

In this example, the element at index 2 (30) is removed, and both the modified list and the removed element are printed.

Using slicing to create a new list:

You can also use slicing to create a new list that excludes the element at the specified index:

python

# Create a list
my_list = [10, 20, 30, 40, 50]

# Remove the element at index 2 (30) using slicing
my_list = my_list[:2] + my_list[3:]

# Print the modified list
print("Modified List:", my_list)

In this example, we create a new list that excludes the element at index 2 (30) using slicing. The modified list is printed without the removed element.

Both methods allow you to remove an element from a list by its index in Python. Choose the method that best suits your needs based on whether you want to keep or discard the removed element.
