Learn Python #6 - Let's List it...

What are Lists?

Lists in Python are the collection of elements of data. What does that mean? Let's check the below examples.

List

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"]
Enter fullscreen mode Exit fullscreen mode

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"]
Enter fullscreen mode Exit fullscreen mode
  • Insert
employee.insert(0, "Efg")
// employee -> ["Efg", "Abc", "Bcd", "Cde"]
Enter fullscreen mode Exit fullscreen mode

The difference between the append and insert methods is that the append add the element at the last position of the list whereas in insert you 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
Enter fullscreen mode Exit fullscreen mode

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]
Enter fullscreen mode Exit fullscreen mode

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"
Enter fullscreen mode Exit fullscreen mode

Find the element by specifying the position and then assign the value.

Conclusion

There are more posts on the way related to the lists...So keep reading.
