Use remove() method to remove elements from the list in Python. Python Lists have various built-in methods to remove items from the list.
list.remove(element)The remove() method removes the first matching element from the list.
Remove element from list Python
Simple example code.
pn = [2, 3, 5, 7, 9, 11]
# remove 9 from the list
pn.remove(9)
print(pn)
# another exmaple
fl = ['Iris', 'Orchids', 'Rose', 'Lavender']
fl.remove('Orchids')
print(fl)
Output:
Remove an item from a list using list comprehension
list1 = [1, 9, 8, 4, 9, 2, 9]
# to remove list element 9
list1 = [ele for ele in list1 if ele != 9]
print(list1)
Output: [1, 8, 4, 2]
Delete an element from a list using the del
list1 = [1, 9, 8, 4, 9, 2, 9]
# Remove list element at 1
del list1[1]
print(list1)
Output: [1, 8, 4, 9, 2, 9]
Delete an element from a List using pop()
We can remove the element at the specified index and get the value of that element.
list1 = [1, 9, 8, 4, 9, 2, 9]
a = list1.pop(1)
print("Item popped :", a)
print("After deleting the item :", list1)
Output:
Item popped: 9
After deleting the item : [1, 8, 4, 9, 2, 9]
The remove() method removes the first occurrence of a specified value. The del statement removes the item at a specified index. The pop() method removes the item at a specified index and returns it. If no index is specified, it removes and returns the last item in the list.
