What are Lists?
Lists in Python are the collection of elements of data. What does that mean? Let's check the below examples.
Let us look at an example
- Example 1:
Let's say we have a list of employees with their name as the list items
employees = ["Abc", "Bcd"]
In the above item, you can add a new item, remove an item, append an item, and furthermore.
Add an item
There are two ways in which we can add a new item to the list.
- Append
employee.append("Cde")
// employee -> ["Abc", "Bcd", "Cde"]
- Insert
employee.insert(0, "Efg")
// employee -> ["Efg", "Abc", "Bcd", "Cde"]
The difference between the
appendandinsertmethods is that theappendadd the element at the last position of the list whereas ininsertyou can specify at what position you want to add the element.
Get the length of the list
employee = ["Efg", "Abc", "Bcd", "Cde"]
len(employee) -> 4
len is useful that helps in getting the length of a list.
Reference a list item by its position
employee = ["Efg", "Abc", "Bcd", "Cde"]
employee[2]
In the [] you need to specify a position of an element that you need a reference to.
Changing an item in the list
employee = ["Efg", "Abc", "Bcd", "Cde"]
employee[1] = "Nitin"
Find the element by specifying the position and then assign the value.
