Check if List is Empty

Write a Python program to check if a list is empty or not.

Visual Presentation:

Sample Solution:

Python Code:

# Create an empty list 'l'
l = []

# Check if the list 'l' is empty using the 'not' keyword
if not l:
    # If the list is empty, print the message "List is empty"
    print("List is empty")

Sample Output:

List is empty

Explanation:

In the above exercise -

l = []  -> This line creates an empty list called 'l'.

if not l:
  print("List is empty")

The above code checks if the list 'l' is empty using the not keyword, which checks if a value is False. If 'l' is empty, the condition is true, and the code block inside the if statement will execute.

Therefore, the output of this code will be "List is empty", since the list l is indeed empty and the code inside the if block is executed.
