Remove List Items
What You'll Learn: In this tutorial, you'll discover how to remove items from a list in Python. It's like taking out pieces from a puzzle that you no longer need.
Remove Specified Item
To remove a specific item from the list, use the remove() method.
Example Code:
thislist = ["apple", "banana", "cherry"]
thislist.remove("banana")
print(thislist)
Output: ['apple', 'cherry']
What's Happening Here?
thislist.remove("banana")removes 'banana' from the list.
If there are multiple items with the same value, remove() will remove the first occurrence.
Example Code:
thislist = ["apple", "banana", "cherry", "banana", "kiwi"]
thislist.remove("banana")
print(thislist)
Output: ['apple', 'cherry', 'banana', 'kiwi']
Remove Specified Index
To remove an item at a specific index, use the pop() method.
Example Code:
thislist = ["apple", "banana", "cherry"]
thislist.pop(1)
print(thislist)
Output: ['apple', 'cherry']
What's Happening Here?
thislist.pop(1)removes the second item ('banana').
If you do not specify the index, pop() removes the last item.
Example Code:
thislist = ["apple", "banana", "cherry"]
thislist.pop()
print(thislist)
Output: ['apple', 'banana']
You can also use the del keyword to remove an item at a specific index.
Example Code:
thislist = ["apple", "banana", "cherry"]
del thislist[0]
print(thislist)
Output: ['banana', 'cherry']
The del keyword can also delete the entire list.
Example Code:
thislist = ["apple", "banana", "cherry"]
del thislist
Clear the List
To empty the list but keep the list itself, use the clear() method.
Example Code:
thislist = ["apple", "banana", "cherry"]
thislist.clear()
print(thislist)
Output: []
What's Happening Here?
thislist.clear()empties the list, leaving it with no items.
