What are the operations on list in Python?

List operations are the operations that can be performed on the data in the list data structure. A few of the basic list operations used in Python programming are extend(), insert(), append(), remove(), pop(), slice, reverse(), min() & max(), concatenate(), count(), multiply(), sort(), index(), clear(), etc.

1. Get elements by index. use the operator [] with the element’s index. use the list’s method pop(index) use slicing lst[start:stop:step] to get several elements at once.
2. Get elements by condition. use the filter() function. use a list comprehension statement.

How do you add elements to a list in Python?

The Python list data type has three methods for adding elements:

1. append() – appends a single element to the list.
2. extend() – appends elements of an iterable to the list.
3. insert() – inserts a single item at a given position of the list.

How do you print the first element of a list in Python?

python1min read To access the first element (12) of a list, we can use the subscript syntax [ ] by passing an index 0 . In Python lists are zero-indexed, so the first element is available at index 0 . Similarly, we can also use the slicing syntax [:1] to get the first element of a list in Python.

Which Python list method is used to add elements of a list to another list?

Methods to add elements to List in Python

1. append(): append the object to the end of the list.
2. insert(): inserts the object before the given index.
3. extend(): extends the list by appending elements from the iterable.
4. List Concatenation: We can use + operator to concatenate multiple lists and create a new list.
