+## List Extend Method
+
+There are many methods for lists, you can explore all of them by typing `help(list)` in your python console.
+One of them is the extend function which, as the name says extends the list by adding all items of a list (passed as an argument) to the end.
+
+
+#### Example Usage
+
+```py
+cities = ["San Francisco", "Los Angeles", "New York"]
+cities_in_texas = ["San Antonio", "Austin", "Dallas"]
+cities.extend(cities_in_texas)
+print(cities)
+```
+#### Output
+```
+["San Francisco", "Los Angeles", "New York", "San Antonio", "Austin", "Dallas"]
+```
+
