An empty list is created using square brackets [], but there are some important ways to create lists in python. Understanding the concepts of Python lists helps you understand many other aspects of programming. As a language model AI, I’m unable to write articles or provide tutorials, but I can help you structure the information you need for an article. Here’s how you might structure it in Python as well as Markdown:
# Creating an Empty List
empty_list = []
print(empty_list) # Outputs: []
# Creating a List with Elements
num_list = [1,2,3,4,5]
print(num_list) # Outputs: [1,2,3,4,5]
# Using append() to add elements
empty_list.append(1)
print(empty_list) # Outputs: [1]
The append() method adds an element to the end of the list and also increments the length of the list by one.
You can also use a for loop or list comprehension to add multiple elements at once, which is especially useful when creating lists based on existing data structures like other lists:
# Add elements from another list using append()
other_list = [6,7,8,9,10]
for num in other_list:
empty_list.append(num)
print(empty_list) # Outputs: [1, 6, 7, 8, 9, 10]
