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.
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)
This method adds the element in the list at any index.
c = [2,4,"vik",76] c.insert(0,"python") print(c)
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)
