How to insert and remove elements from a list in Python

Lists are mutable, meaning that elements of lists can be changed once they have been assigned to variables. We can change an element in a list, we can delete an entire list, and we can add and remove one element from a list after assigning it to a variable.

Add an element to the list

Adding an element to a list can be done in a number of ways:

  • list.append(): This method adds the element at the end of the list.
a = [25,"vinay",45,217]
a.append("rohit")
print(a)
  • list.extend(): This method adds more than one element to the list.
b = [2,45,101]
b.extend(["sunny","sandeep","shashanka"])
print(b)

insert(index, element): This method adds the element in the list at any index.

c = [2,4,"vik",76]
c.insert(0,"python")
print(c)

Remove an element from the list

Removing an element from a list can be done in a number of ways:

  • list.pop(): This method removes the last element from the list.
d = [12,34,56,78,89,0]
d.pop()
print(d)
  • list.pop(index) If the index is mentioned, it removes the mentioned item from the list.
e = [2,4,'vik',76]
e.pop(2)
print(e)
  • list.clear() This deletes all elements in the list. The list is then called an empty list.

f = [2,4,"data ",45,217,"structure"]
f.clear()
print(f)
