List Operations: A Beginner's Guide | Python Tutorial #6 | Part - 2
In Python, there are several operations that can be performed on lists. Here are a few examples:
Indexing: You can access individual elements of a list by using an index in square brackets. For example, given the list my_list = [1, 2, 3], you can access the first element with my_list[0].
Slicing: You can extract a sub-list from a list by using slicing. For example, given the list my_list = [1, 2, 3, 4, 5], you can get the sub-list [2, 3, 4] by using the slice my_list[1:4].
Concatenation: You can combine two lists into a single list using the + operator. For example, [1, 2] + [3, 4] will produce the list [1, 2, 3, 4].
Repetition: You can create a new list by repeating an existing list using the * operator. For example, [1, 2] * 3 will produce the list [1, 2, 1, 2, 1, 2].
Membership: You can test whether an element is in a list using the in operator. For example, 3 in [1, 2, 3] will return True, while 4 in [1, 2, 3] will return False.
Length: You can get the length of a list using the len() function. For example, len([1, 2, 3]) will return 3.
Modification: You can modify the elements of a list by assigning new values to them. For example, my_list = [1, 2, 3] and then my_list[1] = 4 will change the list to [1, 4, 3]. You can also modify multiple elements at once using slicing.
Deletion: You can delete elements from a list using the del statement. For example, del my_list[1] will remove the second element from my_list. You can also delete a slice of elements using slicing.
