Python Append to Empty List
In Python, we can create an empty list and then later append items to it, using the Python append() function.
Example:
In this example, we will first create an empty list in Python using the square brackets and then appended the items to it.
Python3
# create an empty lista = []# append items to ita.append(10)a.append(20)a.append(30)print("Values of a:", a)print("Type of a:", type(a))print("Size of a:", len(a)) |
Output:
Values of a: [10, 20, 30] Type of a: <class 'list'> Size of a: 3
Declare an empty List in Python
Lists are just like arrays, declared in other languages. Lists need not be homogeneous always which makes it the most powerful tool in Python. A single list may contain data types like Integers, Strings, as well as Objects. Lists are mutable, and hence, they can be altered even after their creation.
