+## List Append 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 append function which, as the name says appends the argument given list.
+
+#### Example Usage
+
+```py
+words = ["I", "love", "Python"]
+words.append("very much")
+print(words)
+```
+#### Output
+```
+["I", "love", "Python", "very much"]
+```
+ As you might have noticed the element `"very much"` is appended to the list.
+
